I really liked how you got into the Thunderbolt details. I have run an eGpu with an old i5 4 core laptop and now a i5 12500H laptop. The sweet spot for me seemed to be an RX 3070, and a 3080 was only marginally better, but I can see how a 4090 would be substantially better as it has sooo much more power. What I have done recently is move from a big eGPU box to a GPD G1 (a little portable RX 7600M XT 8Gb card and Dock), and this does very well and fits in my bag. I have run an USB/NVME with this also and get 10Gbps speeds out of that, and also plug the network in. SO, basically a TB dock and eGPU. It also has Oculink so potential for a full 4 lanes of PCIe if you get a laptop with such a connector or add one yourself.
@@MrOB099 Not silent when gaming for sure, but not really loud either. I would say it is not louder than a gaming laptop when you are playing. Even then the sound is more like an air rushing rather than annoying fan whine and you can put the box further away. It also does well with cooling too. I kept the 100w bios and I understand if you do switch to the 120w bios the noise goes up and you get maybe only 8% more performance. The actual negatives I would say (aside from price) are AMD support that seems to leave the mobile GPUs out of special features, though that may be in part due to the "hybrid" nature of the setup iGPU+eGPU. However, I use something called Lossless Scaling (available on steam) to get upscaling and frame generation (great software that works with all GPUs).
What laptop series brand do you have? Since you mention 12 gen intel series? I have 11 gen intel i5 everything above 10 gen intel is pretty future proof imo
Just some info, the PCIE lane depends on what thunderbolt controller being used in the host device. For example, I'm using huawei matebook x pro which using JHL6240 thunderbolt 3 controller, it only has 2 pcie lanes physically. But on some other laptop, like lenovo ThinkPad T480, it uses JHL6540 thunderbolt 3 controller which has 4 pcie lanes.
I’m very happy with my RTX4070 Super eGPU. I have it connected to a 12th generation DELL XPS through Thunderbolt 4, and it works great. When I want to game, I connect it to my 28-inch 4K BenQ monitor. When I want to work, I disconnect it, saving energy. I don’t know, for me, it’s amazing. I don’t need a desktop tower having such an interesting setup
@xavierrodriguez-sr8cv It's great, I haven't run into any cpu bottlenecks, and I don't have any issues with heat. At 30 watts, it won't much go over 75c under load. It's a nice little setup with my 1440p monitor. If you really want to there are ways to push the TDP up to like 60watts plus. ETA prime has a video doing this, the single core performance has a huge increase.
@gabealberro6081 Just went with a razor core x for simplicity. You could probably a lot better for cheaper. It works great and all but I don't know that it's worth the price.
This is quite in depth. I love how you _had_ to prove that the SSDs cause negligible performance degregation. Armchair commenters completely forgot that as much as possible things are loaded into memory than read from disks. Yeah your game loading time would take a probable hit but the effect to FPS should be negligible.
Incredibly informative. Thank you! Laptops with dGPU's are pretty much useless because of the poor battery life. Being able to plug an eGPU and not needing to invest on a desktop will be really nice. One device(and port) to rule them all.
Informative video, can clearly see that 4090 is heavily bottlenecked by the thunderbolt connection. There are oculink adaptor that uses the laptop nvme ssd (pcie x4) slot for external gpu connection and oculink supported pcie connector for gpu which gives a much higher bandwitdth compare to TB. In theory it should improves the bottleneck situation significantly but it is a much more DIY-ish solution.
Hopefully Thunderbolt 5 will eliminate or drastically reduce these limitations and we will start seeing a lot more people using external GPUs. Thunderbolt 5 promises double the current PCI throughput, or 64 GB/s for external graphics cards.
First of all, thank you for the video, I feel me so honored to be subscribed to this channel due to the above-average quality, especially because it is educational and very informative! I want to ask you something, I have a laptop with an i7 10875H and an RTX2070, do you think an EGPU with an RTX4060 would give me a gain in performance? Thanks for the video and if you can answer me! (sorry for my bad English)
The only other considerations which would be interesting and perhaps prudent, (especially given this day and age of all things AI,) is better understanding the impact which would might persist or be hindered when utilizing an eGPU arrangement with uthose higher end 4,000 series (4070 and up) GPUs; which now also include onboard TPUs ("tensor processing units") for the purpose of localized GPT and AI (LLM & Generative) checkpoint file "training" and local "iterations".
idk why one would want this, but okay. i have a desktop with a 5800x3d and a rtx 4080, but every time i sit to use my laptop with its i7 10750k and rtx 2070, i cannot help but be impressed to this day with how well the damn thing performs. it was my first ever high end laptop, and from its longevity while retaining its awesomeness, i'd say the best purchase yet, even though it was expensive. thing's a joy to use 3 years later even coming from my much more powerful desktop.
I won't deny that i'm confused, mainly about how choose a good egpu for my mini-pc, i got lost about the thunderbolts, the Watts and how my setup can match or not with the graphic card's bottleneck :\
For the mini PC consider using m.2. eGPU. It works way better in terms of bandwidth and it's cheaper. Also, I have some other eGPU videos, maybe it will help you
On MSI Afterburner there is a monitoring option for BUS Usage. You have to monitor it. And yes, frame time are so horrible, and it would be better 60fps straight line, than 120fps zigzag.
this is why i got a mini pc with oculink + 4070 instead, since i'm not interested in 4k gaming (yet), just 1440p. oculiink goes up to 63gbps on PCIE4x4 so it's pretty much native.
Around 4th minute, I think there's a misunderstanding about how the GPU / CPU percentage is expressed in Afterburner for example. If it indicates that GPU is being used at 99%, that means that the workload of that particular game or application is being 99% handled by the GPU (as it should when things run properly). Therefore Afterburner can indicate 99% GPU for a workload that requires 320 watts or 450 watts, since it is not related to the full GPU cores being necessarily in use.
Yes, except that when using that same GPU in a PC, the power consumption/GPU load is usually predictable. In the case of eGPUs, it's always close to 100%, so I had to point this out so that other viewers don't get confused and think the video card is running at 100% of its capabilities. At least it's some kind of orientation :)
Great video! Do you think that eGPU could be a good option for 3D offline rendering (like using Blender)? If I understood correctly the bottlenecks affect mainly real time rendering, but for offline purposes, the rendering power of the GPU should be exploited entirely. Maybe it could create some issues during the preview, but not during the rendering, am I wrong?
thanks for informing me in this video, by the way do u know any good m.2 to usb c adapters that are high quality and arent sketch? it would be greatif u know some
I guess that I can't cover all the benchmarks, but I tried my best. Check my latest video with eGPU vs GPU, I tested Twinmotion and Adobe Premiere Pro there
Great video, glad i discovered this video. Can you please do a comparison of Image generation using eGPU vs iGPU and puting the gpu in your PC that you might build next. You can use the Automatic1111 as it's easy to setup. Using egpu for this machine learning or generative task would be a great use case as there is no video output like games. it would be like mining as mining only needed 4x pcie.
@@trysometech52 i think my previous comment was deleted, just automatic1111 in dgpu and egpu see time it takes to generate, so use free to use upscaling model and try to upscale to 8k and see the time it took in both gpu. also try open GPT model.
I can seem to find the information about the difference between using the TH3P4G3 Thunderbolt 60w vs the 85w. I wanna run RTX 4070 ti with external SSD. Which should i get? Does it make a difference? Why are there 2 different wattage rating? Thanks
How's you performance recording vs not recording ❓🤔 Also do you think there's any way to increase the bandwidth even a little from like 24 gbps to 28 or something
Performance is not affected at all, maybe ~1% sometimes. I think the only way to increase bandwidth is to wait for Thunderbolt 5, haven't heard of any other ways to do it :D
so theoretically, this would be closer to a desktops performance with a lower end gpu, if this is the case, I'd like to see what a 3080 or maybe 4070 can do in the enclosure.
im also using TH3P4G3 with amd cpu 6800u and nvidia gpu rtx 3070ti i saw your aida64 result and its only getting 2700MB/s on my device i got 3000MB/s, i guess its the cpu or cable that limit the bandwidth?
Hey, could you also please share your Memory Write numbers? The thing is, this is not my result, I used it from another guy's video since I already returned my laptop to the store and couldn't do my own test. But this result matched what I found on the internet about eGPU, so I used it.
@@trysometech52 sure, i just uploaded a short video, i tested it using cudaz heres the rounded numbers Host to Device: 2700MB/s Device to Host: 3000MB/s
Does the chip have the thunderbolt controller built into the SOC, or is the controller on a separate chip: the chipset? If the latter is the case it nukes performance.
The latter, TB4 controller on Raptor Lake Hs, not integrated. This review is flawed. "As this is based on Intel's desktop silicon and PCH, what you won't find here is integrated Thunderbolt 4 support. Instead, OEMs will need to add that via discrete TB4 controllers," - AnandTech
I was thinking about getting eGPU because my laptop only lacks a stronger GPU (my current GPU is GTX 1650 ddr6). I wish there was a way to change the GPU, but unfortunately laptops don't work like that.
So, I didnt really get an answer... How do graphics cards scale on the eGPU bandwidth? Why didn't we see performance of desktop vs GPU and then with multiple different GPU's? additionally, how do we account for the bottleneck being a difference in bandwidth allocation vs the CPU's performance? If a RTX 4090 with this CPU and this version of thunderbolt gives me X% of performance relative to a desktop setup, do we see a reduction in relative performance when using RTX 4080, 4070?
You'll find most of the answers in my latest video. But still I don't have that many GPUs to give you answer in percent or something like that. And anyway it's more depending on the game you play, more CPU demanding = more performance loss.
Thanks for the video! Question, is thunderbolt 4? Thinking for legion go since i got a gpd g1 and having issues with z1 extreme thats on the legion go.
Sorry but I didn't get your question. And the gpd g1 has Oculink, don't you wanna go for GPD handheld to use that port? It's way better then USB4 on Legion Go
@trysometech52 my bad didn't catch that part! Thanks for the video. Plan on doing a video of how to set it up, power supply advice etc? That'd be awesome.
How to set it up you can find here - ruclips.net/video/EOsGqAeyCtA/видео.html As for the PSU - depends on power consumption of your GPU + ~150W. And don't get cheapest one like I did there for the testing :D
I looked for information on the Internet but did not find it, please answer: can I use the HDMI 2.1 instead of thunderbolt 4 for egpu, where the bandwidth is 48?!
Why does it cost me as much as a new computer to buy a eGPU setup? I might as well get a new DIY computer instead of getting a upgraded GPU via external GPU.
hi i want to ask, is it okay if i use egpu for 3d rendering ? i got my dell precision 5560 i9 11th gen laptop, but wanna use external gpu such as rtx 3080 ti for my 3d rendering (sketchup/ lumion / enscape)
I'm considering buying an Egpu for playing games on my 4K 60hz TV (obviously DLSS ON). My laptop has more or less the same specs of yours (i7-12700h, 64gb DDR5, integrated 3050Ti 45watt tdp) Would you recommend it? Looking for a 3070, will it be sufficient?
That could be a good setup, but before that you better check my latest video, where I compared PC performance to eGPU, so you will know what to expect from it
Wait, so if I get a RTX 3060 or 4060 there should be no thunderbolt bottlenecking right? Since, the RTX 3060 has a bandwidth of 15GB/S and RTX 4060 has a bandwidth of 17GB/S and thunderbolt can support up to 22GB/S. So, from what I understood only high-end GPUs have higher bandwidth than the 22GB/S are bottlenecked. Am I wrong? does the 15GBPS and 17GBPS bandwidth on the GPU mean something else?
Hey, where you got that information from? 3060 or 4060 using regular PCI-E lines, which has way more bandwidth speed. I am pretty sure that bottleneck will be anyway. I got some benchmarks for future video, it will cover all your questions
@@alanzowo7710 from where did you get those numbers 15GBPS and 17GBPS bandwidth? , if it's right i thick gpu will work well, i think if we used external monitor will be batter
thanks for vedio , cna you please try it in external monitor ? i thinck it will be batter because output will not pass back to internal monitor , do you thick that ?
Привет, а есть ли это видео на русском? А то не понятно, стоит ли для тандарболт 4 покупать внешку или нет. Или у вас тандарболт просто порезаный. И пробовали ли вы подключать через этот тандарболт монитор 4к 120Hz?
Does this mean, that there's no need for a high end laptop will an 12core laptop with USB4 be perfect? I'm considering downsizing my setup...moving from a full desktop tower to either a cheap laptop or a MINI PC with USB4 features.
Most likely yes, but CPU bottleneck is still real, so it should be balanced build anyway. p.s. I'm sure you'll benefit from such a transition, especially with a mini PC. There are a lot of trade-offs in this approach. I did it before and after that switched back to desktop PC again
@@trysometech52 True, I was thinking about mini PC as a backup PC too I have a Blackview N94 crappy 4core 4thread CPU barely plays games but great as a HTPC
@@trysometech52 Thunderbolt uses USB PowerDelivery. So, if your power source does not meet the power required for your device, it will refuse to charge. For example, i was testing a Lenovo Dock via Thunderbolt with a 90W power adapter, but my HP tablet refused to charge because a pop up with a message saying that the USB source do not have sufficient power. Tested again but with a brick of 135W, and the charging is working fine. Maybe if you deactivate your discrete GPU via BIOS settings and let only the integrated graphics works, your aero laptop will charge with Thunderbolt because, it will require less power to the PowerDelivery controller.
@@dylancalamateo6062 hmm, but at the same time It was charging form another 65W charger as far as I remember. Can't double check that now, since I don't have that laptop. Anyway, thanks for the info!
Привет! Модель написана примерно в начале видео 0:46 Касательно thinkpad, тут всё зависит от целей использования и видеокарты, к которой ты его подключишь. Короче просто так не ответить) Но в целом справится с нетребовательными играми
@@trysometech52 Спасибо за ответ. Просто к примеру если у меня thinkpad t14s есть и подключить к нему к примеру также egpu только GeForce 1660 можно ли будет поиграть в игры из видео к примеру на не высоких настройках? Насколько видеокарта будет реализовывать свой потенциал при использовании egpu? Или нужно брать более мощную видеокарту чтоб что-то можно было поиграть с использованием ноутбука и egpu? Просто переживаю что видеокарта на таком слабом железе не реализует весь свой потенциал ? И ещё вопрос есть ли смысл попробовать подключить MacBook Pro на intel процессоре или лучше не стоит пробовать так как мак сам по себе не очень для игр?
Однозначного ответа нет, не хочу просто обнадёжить тебя пустыми обещаниями) Но чем менее процессорозависимая игра - тем лучше она будет работать и "раскрывать" eGPU. И как ты уже видео по другому видео, вне зависимости от видеокарты будет теряться часть производительности. Так что 1660 вполне может стать хорошей парой для твоего ноута, если ты не планируешь играть в игры как Battlefield 2042) Про мак не знаю, лично не пользовался. Но если там мощнее проц и поставить на него винду, то скорее всего лучше себя проявит
if you use an egpu with an external monitor, is there more latency than if you had a discrete graphics card and were using either the laptops screen or an external monitor?
I just got a similar laptop with 13705H + 4050 80W TGP, so I guess I only get egpu if the price isn't to bad because its seem there's no guanrantee it may be good?
The biggest difference is that m.2 is not hot-swapable, while thunderbolt is. And honestly the performance gains are nice over thunderbolt 3 and 4, but not 5, so I'm just waiting to buy a laptop and egpu dock over Tb5 to get fast speeds without having to reboot.
@@_reZ will it be a big difference in performance ? I have a egpu dock all setup but it’s through m.2 and I thought of using a m.2 to thunderbolt adapter and I just need to know difference in performance realy
I plan to make a video with a detailed comparison as I often get questions like this :) But you'll get a way better performance through m.2. (if it's PCIe 4.0) and a little bit better if it's PCIe 3.0
@@trysometech52 I see, but I feel like connecting it to a m.2 slot kind of defeats the point of having an egpu as It’s basically a pc at this point, I’ve decided to purchase a thunder bolt 4 ssd enclosure so that I can have much more flexibility on my egpu :)
Can a VGA with an internal Nvidia GPU such as an RTX 4060 use an Nvidia GPU too? I have used Adt Link NVME, using a GTX 1650 laptop, I can't use an RTX 4060 GPU, I have to use an AMD RX6600 VGA
Can I hook up an egpu to a USB 4 40 gbps port even if it does not say that it is thunderbolt 3 compatible? I plan to use the x870e carbon wifi motherboard together with a gigabyte 3070 gaming box. I want to have a 5th (and possible 6th) screen working, and I use an AMD cpu with no integrated graphics and I do not want to use the second PCIE slot on the motherboard, because then the lanes get shared over the two slots (bifurication) to x8 / x8. So, I thought, let me use an egpu for the 5th screen and not gimp my soon rtx 5090 on the first PCIE slot. Will this work?
Interesting question. Yes it will work, but man, you need a monitors with a Daisy chain so hard. I think that could be easier solution instead of eGPU. Also, what CPU do you currently have? Btw, it's PCIe 5.0, so I can just guess that if 5090 will be also on 5.0, there will be enough bandwidth even with 8 lines, but that's just a guess
For people who use vsync and caps fps at 60 or 90 etc, this would be plenty bandwidth for gaming, i use a older 4k tv and it is vsync 60fps and its great for gaming, because the low 60fps keeps my 4080 at lower usage and cooler meaning the fans dont have to run all the time. i could easily run my gpu externally if i had the thunderbolt connection, but sadly amd dont have it. I could use oculink and might make my own enclosure one day.
Hello i have i7 1360p 16gb ram samsung galaxy book. Will aorus gtx 1070 gaming box go good with that? Also tell me other compatible options to avoid bottleneck

Hi I want to buy Lenovo legion slim 5 (13700H, 4060) and I only use it for architecture design and rendering (using Revit and Twinmotion). and for heavy architecture scenes 8Gb of vram on 4060 is not enough. I want to help me what external gpu should I get. and is it worth it. and how much performance I gain relative to my dedicated 4060 gpu. thanks for awesome videos
Hi, thanks man! I'm not sure if I can help you with good advice as I've never used the programs you mentioned. The more CPU dependent the computation is, the more performance you will lose by using an eGPU, as I tried to explain in the video
I would say get a GPU with the vram you need. Also take a look at eGPU for productivity tests as you still have the PCIe limit here and it would depend how much those programs offload to the GPU and how much they interact. Performance wise I don't think you would see a massive gain over the laptop 4060 (assuming it is a high wattage version) unless you stepped up to 4080/90, here is certainly room. Do you want to drop the money for a 4090 desktop card or maybe look at a 4090 laptop with 16Gb vram?

Thanks for your work, it's very useful. I hope our dream of a sleek laptop that simply docks into a gaming rig will become true soon :)
It depends on what you consider sleek, but laptops with OCuLink ports, such as some Thinkpads, already offer closer to desktop performace with eGPUs.

You can manually creata a fan curve on the Aero so it won't make noise while browsing and set the fan to 50% while gaming.
What was the conclusion? Is the external GPU recommended or not in this video?
Excellent video. Thunderbolt 5 seems promising.
Great video. Excellent explanation👍
If you decide to do a revisit, I'd recommend to check if turning off Afterburner and RTSS will help in games with low performance/stutters.
Basically, eGPUs will remain bottlenecked until we get mainstream Thunderbolt 5 support
On MSI Afterburner there is a monitoring option for BUS Usage. You have to monitor it. And yes, frame time are so horrible, and it would be better 60fps straight line, than 120fps zigzag.
I wish I had known about that monitoring option before. But I can't agree about frame time with you. Most of the time it was pretty good and stable
This frame time becuse of the bug in Afterburner. It don't support external GPU.
this is why i got a mini pc with oculink + 4070 instead, since i'm not interested in 4k gaming (yet), just 1440p.
oculiink goes up to 63gbps on PCIE4x4 so it's pretty much native.
N1 That is the Future for a lot of PCs i think. Litte plus PC.
Around 4th minute, I think there's a misunderstanding about how the GPU / CPU percentage is expressed in Afterburner for example. If it indicates that GPU is being used at 99%, that means that the workload of that particular game or application is being 99% handled by the GPU (as it should when things run properly). Therefore Afterburner can indicate 99% GPU for a workload that requires 320 watts or 450 watts, since it is not related to the full GPU cores being necessarily in use.
Yes, except that when using that same GPU in a PC, the power consumption/GPU load is usually predictable. In the case of eGPUs, it's always close to 100%, so I had to point this out so that other viewers don't get confused and think the video card is running at 100% of its capabilities. At least it's some kind of orientation :)
It's time for Thunderbolt 5 video, waiting for it.
They don't exist yet, so we'll wait together
Great video!
Do you think that eGPU could be a good option for 3D offline rendering (like using Blender)? If I understood correctly the bottlenecks affect mainly real time rendering, but for offline purposes, the rendering power of the GPU should be exploited entirely. Maybe it could create some issues during the preview, but not during the rendering, am I wrong?
Which graphics card should you get? Use a Legion Go and want to get a 4070 super.
Zadrova! Super vidic! Only one question. Is there a reason as to why that the 1% and the 0.1% are showing 0/1 FPS ?
Hey, thanks! Just a wrong settings for the MSI Afterburner, now I know how to avoid that
thanks for informing me in this video, by the way do u know any good m.2 to usb c adapters that are high quality and arent sketch? it would be greatif u know some
I wish you had done a couple of creator benchmarks, Blender, for example. But thanks.
I guess that I can't cover all the benchmarks, but I tried my best. Check my latest video with eGPU vs GPU, I tested Twinmotion and Adobe Premiere Pro there
Great video, glad i discovered this video. Can you please do a comparison of Image generation using eGPU vs iGPU and puting the gpu in your PC that you might build next. You can use the Automatic1111 as it's easy to setup. Using egpu for this machine learning or generative task would be a great use case as there is no video output like games. it would be like mining as mining only needed 4x pcie.
Hey, thanks :)
If it's not CPU intensive, it should work fine. And I can run this test for you, but maybe next month. I'm just not ready for that yet
@@trysometech52i'd be interested too
Hey, is there any specific settings or cases that I should use for generating images?
@@trysometech52 i think my previous comment was deleted, just automatic1111 in dgpu and egpu see time it takes to generate, so use free to use upscaling model and try to upscale to 8k and see the time it took in both gpu. also try open GPT model.
@mutantCybernetics @lufenmartofilia5804
As I promised, new video is there with the benchmarks you asked for
Interesting that you can use the laptop display as in the past you could only output to and external monitor I think.
I can seem to find the information about the difference between using the TH3P4G3 Thunderbolt 60w vs the 85w. I wanna run RTX 4070 ti with external SSD. Which should i get? Does it make a difference? Why are there 2 different wattage rating? Thanks
I don't know, not sure that there is some additional difference between them. It's better to ask the AliExpress seller about it
im so glad my notebook has 5800H CPU , so i can do this now too. I hope it can work fine with my rtx 4070 ti , thunderbolt 4 .
Not sure about that, you need support of USB4, and AMD support it starting from 6xxx generation
How's you performance recording vs not recording ❓🤔
Also do you think there's any way to increase the bandwidth even a little from like 24 gbps to 28 or something
Performance is not affected at all, maybe ~1% sometimes.
I think the only way to increase bandwidth is to wait for Thunderbolt 5, haven't heard of any other ways to do it :D
so theoretically, this would be closer to a desktops performance with a lower end gpu, if this is the case, I'd like to see what a 3080 or maybe 4070 can do in the enclosure.
Not exactly, check my other GPU vs eGPU video, I tested RTX 2060 there
I have a Lenovo AIO i7 13th gen with 32 GB ram, Intel UHD graphics , thunderbolt 3 ports . Which eGPU should i use ?
im also using TH3P4G3 with amd cpu 6800u and nvidia gpu rtx 3070ti
i saw your aida64 result and its only getting 2700MB/s
on my device i got 3000MB/s,
i guess its the cpu or cable that limit the bandwidth?
Hey, could you also please share your Memory Write numbers?
The thing is, this is not my result, I used it from another guy's video since I already returned my laptop to the store and couldn't do my own test. But this result matched what I found on the internet about eGPU, so I used it.
@@trysometech52 sure, i just uploaded a short video, i tested it using cudaz

Question, how to up scale in legion go ? And what best setting for legion go for external monitor or internal from your experience
Does the chip have the thunderbolt controller built into the SOC, or is the controller on a separate chip: the chipset? If the latter is the case it nukes performance.
The latter, TB4 controller on Raptor Lake Hs, not integrated. This review is flawed. "As this is based on Intel's desktop silicon and PCH, what you won't find here is integrated Thunderbolt 4 support. Instead, OEMs will need to add that via discrete TB4 controllers," - AnandTech
BRILLIANT THANYOU
I was thinking about getting eGPU because my laptop only lacks a stronger GPU (my current GPU is GTX 1650 ddr6). I wish there was a way to change the GPU, but unfortunately laptops don't work like that.
So, I didnt really get an answer... How do graphics cards scale on the eGPU bandwidth? Why didn't we see performance of desktop vs GPU and then with multiple different GPU's? additionally, how do we account for the bottleneck being a difference in bandwidth allocation vs the CPU's performance?
If a RTX 4090 with this CPU and this version of thunderbolt gives me X% of performance relative to a desktop setup, do we see a reduction in relative performance when using RTX 4080, 4070?
You'll find most of the answers in my latest video.
But still I don't have that many GPUs to give you answer in percent or something like that. And anyway it's more depending on the game you play, more CPU demanding = more performance loss.
Thanks for the video! Question, is thunderbolt 4? Thinking for legion go since i got a gpd g1 and having issues with z1 extreme thats on the legion go.
Sorry but I didn't get your question. And the gpd g1 has Oculink, don't you wanna go for GPD handheld to use that port? It's way better then USB4 on Legion Go
@trysometech52 I'm sorry. I was talking about the egpu dock that you were using in your video. The aliexpress one. It's thunderbolt 4 yes?
Like I said in this video, every eGPU dock is Thunderbolt 3. But they are TB4 compatible and got same bandwidth speed
@trysometech52 my bad didn't catch that part! Thanks for the video. Plan on doing a video of how to set it up, power supply advice etc? That'd be awesome.
How to set it up you can find here - ruclips.net/video/EOsGqAeyCtA/видео.html
As for the PSU - depends on power consumption of your GPU + ~150W. And don't get cheapest one like I did there for the testing :D
Why didn't you show us the GPU bus consumption as long of the GPU data overlay of the Riva turner?
At the time of the video, I didn't know I could do that.
I looked for information on the Internet but did not find it, please answer:
can I use the HDMI 2.1 instead of thunderbolt 4 for egpu, where the bandwidth is 48?!
Because that is not possible. HDMI is for video/audio signal, and Thunderbolt is for data/image signal.
could u tell me what's an optimal graphics card for i9-13900h (TDP 45W) to avoid the bottleneck?
Personally, I would recommend a 3080 12gb or 4070. Both future proof, one uses slightly less power, the other goes for cheaper on eBay.
I connected a 4070 egpu to i7 intel iris xe laptop (with thunderbolt 3) but get 40 fps on cyberpunk 2077, any advice for better performance?
Wait just 40 fps?
Probably should cap it to 4k 60 vsync. when connected too external display. lower the gpu utilization down by 15% too reduce stutter.
Why does it cost me as much as a new computer to buy a eGPU setup? I might as well get a new DIY computer instead of getting a upgraded GPU via external GPU.
hi i want to ask, is it okay if i use egpu for 3d rendering ? i got my dell precision 5560 i9 11th gen laptop, but wanna use external gpu such as rtx 3080 ti for my 3d rendering (sketchup/ lumion / enscape)
Hello, which edition of RTX4090, did you use ? Thank you.
Hey, it was Inno3D GeForce RTX 4090 iChill X3 24G
I'm considering buying an Egpu for playing games on my 4K 60hz TV (obviously DLSS ON).
My laptop has more or less the same specs of yours (i7-12700h, 64gb DDR5, integrated 3050Ti 45watt tdp)
Would you recommend it?
Looking for a 3070, will it be sufficient?
That could be a good setup, but before that you better check my latest video, where I compared PC performance to eGPU, so you will know what to expect from it
Hello, can I ask what eGPU you used. I have found many don't support higher end graphics cards due to under powered power supplies.
hey, you can find a link in the description

Wait, so if I get a RTX 3060 or 4060 there should be no thunderbolt bottlenecking right? Since, the RTX 3060 has a bandwidth of 15GB/S and RTX 4060 has a bandwidth of 17GB/S and thunderbolt can support up to 22GB/S. So, from what I understood only high-end GPUs have higher bandwidth than the 22GB/S are bottlenecked.
Am I wrong? does the 15GBPS and 17GBPS bandwidth on the GPU mean something else?
I'm just really confused about this right now since I can't really find many videos about this so pls help.
Hey, where you got that information from? 3060 or 4060 using regular PCI-E lines, which has way more bandwidth speed. I am pretty sure that bottleneck will be anyway. I got some benchmarks for future video, it will cover all your questions

bro, Thanks 👍
Was there any difference in performance using the laptop screen vs. an external screen?
Yes, there will be a better performance on external monitor and reason was explained in the video
Does this mean, that there's no need for a high end laptop will an 12core laptop with USB4 be perfect? I'm considering downsizing my setup...moving from a full desktop tower to either a cheap laptop or a MINI PC with USB4 features.
Most likely yes, but CPU bottleneck is still real, so it should be balanced build anyway.
p.s. I'm sure you'll benefit from such a transition, especially with a mini PC. There are a lot of trade-offs in this approach. I did it before and after that switched back to desktop PC again

you couldnt charge your laptop via tb port on aero because of the rtx 4050, im guessing your lenovo is onboard graphics?
Yes, that's correct. Can you please explain to me how GPU/iGPU related to the charging?
@@trysometech52 Thunderbolt uses USB PowerDelivery. So, if your power source does not meet the power required for your device, it will refuse to charge. For example, i was testing a Lenovo Dock via Thunderbolt with a 90W power adapter, but my HP tablet refused to charge because a pop up with a message saying that the USB source do not have sufficient power. Tested again but with a brick of 135W, and the charging is working fine. Maybe if you deactivate your discrete GPU via BIOS settings and let only the integrated graphics works, your aero laptop will charge with Thunderbolt because, it will require less power to the PowerDelivery controller.
@@dylancalamateo6062 hmm, but at the same time It was charging form another 65W charger as far as I remember. Can't double check that now, since I don't have that laptop. Anyway, thanks for the info!
Привет а что за модель ноутбука была у тебя кроме thinkpad ? И насколько thinkpad t14 хорош для egpu? Или он совсем слабый для этих целей?
Привет! Модель написана примерно в начале видео 0:46
Касательно thinkpad, тут всё зависит от целей использования и видеокарты, к которой ты его подключишь. Короче просто так не ответить) Но в целом справится с нетребовательными играми
@@trysometech52 Спасибо за ответ. Просто к примеру если у меня thinkpad t14s есть и подключить к нему к примеру также egpu только GeForce 1660 можно ли будет поиграть в игры из видео к примеру на не высоких настройках? Насколько видеокарта будет реализовывать свой потенциал при использовании egpu? Или нужно брать более мощную видеокарту чтоб что-то можно было поиграть с использованием ноутбука и egpu? Просто переживаю что видеокарта на таком слабом железе не реализует весь свой потенциал ?
И ещё вопрос есть ли смысл попробовать подключить MacBook Pro на intel процессоре или лучше не стоит пробовать так как мак сам по себе не очень для игр?
Однозначного ответа нет, не хочу просто обнадёжить тебя пустыми обещаниями) Но чем менее процессорозависимая игра - тем лучше она будет работать и "раскрывать" eGPU. И как ты уже видео по другому видео, вне зависимости от видеокарты будет теряться часть производительности. Так что 1660 вполне может стать хорошей парой для твоего ноута, если ты не планируешь играть в игры как Battlefield 2042)
Про мак не знаю, лично не пользовался. Но если там мощнее проц и поставить на него винду, то скорее всего лучше себя проявит
but can you connect 2x usb c on your external EGPU ?
I'm planning to trade in my i3 lga 1200 for any i7 thunderbolt laptop. Would tb4/pcie/oculink be needed for least bottleneck on a 3080?
if you use an egpu with an external monitor, is there more latency than if you had a discrete graphics card and were using either the laptops screen or an external monitor?
No, it doesn't affect latency

Does this dock power on and power of with the notbeook or would it be running constantly even if no host is connected.
It turns off once you unplug the Thunderbolt cable

Are you sure there isnt a ram bottleneck? I see it at almost 15gb used in every game and you only have 16gb

How about the MacBook Pro m4 has a thunderbolt 5?
Unfortunately M-based Macbooks won't work with eGPU
Is m.2 or thunderbolt better in ur opinion? Idk which one to choose
The biggest difference is that m.2 is not hot-swapable, while thunderbolt is.

So, I thought, let me use an egpu for the 5th screen and not gimp my soon rtx 5090 on the first PCIE slot. Will this work?
Interesting question. Yes it will work, but man, you need a monitors with a Daisy chain so hard. I think that could be easier solution instead of eGPU. Also, what CPU do you currently have?
Btw, it's PCIe 5.0, so I can just guess that if 5090 will be also on 5.0, there will be enough bandwidth even with 8 lines, but that's just a guess

Hi, thanks man! I'm not sure if I can help you with good advice as I've never used the programs you mentioned. The more CPU dependent the computation is, the more performance you will lose by using an eGPU, as I tried to explain in the video
I would say get a GPU with the vram you need. Also take a look at eGPU for productivity tests as you still have the PCIe limit here and it would depend how much those programs offload to the GPU and how much they interact.
Performance wise I don't think you would see a massive gain over the laptop 4060 (assuming it is a high wattage version) unless you stepped up to 4080/90, here is certainly room. Do you want to drop the money for a 4090 desktop card or maybe look at a 4090 laptop with 16Gb vram?
