My Pi 5 8GB has bad silicon so cant be overclocked by even a Hz without issues. Happy with the default speed though. Love the channel. You converted me to KDE and that ice tower.
You had me going there for a second, until I realized I was looking at a PI0 on fire.
I got chance to test out a handful of Pi5s - both 4GB and 8GB and only a very few of them get overclocked beyond 2.8GHz, and more than half don't overclock at all!
That being said, I noticed one at 2.7GHz performed real tasks like faster than a 3Ghz overclocked including GPU rendering.
I would say take your expectation of performance with a grain of salt!
It's nice that the Raspberry Pi Foundation have recognised that you can overclock your RPI5 but owning one you can actually overclock would be nice lol
Thank you my friend! This was quite useful.
Many thanks. Very interesting results.
Another great video from you, thank you very much!
Is it possible that you can also test the Argon NEO 5 M.2 NVMe PCIE Case for the Raspberry Pi 5?
Great video, I’m just confused why so many think overclocking improves emulation when it has little to no effect because emulation is software based and not hardware related. This is like playing snes on a 1998 pc vs playing it on a 2024 pc the results won’t change when it’s software based.
You can consider an emulator to be a "software middle man" that translates one CPU instruction set to another - so just by doing that it is adding load to the native CPU that wouldn't be there running a native program.
In theory, the more CPU power (and RAM) that you have, the faster that emulator can work but there is a limit after which it can go no faster, so overclocking becomes pointless. The older the emulated machine is, the sooner that limit will be reached so what you're seeing on the SNES is entirely expected - so quite possibly a machine from 1998 might well run as well as one from 2024, if you just run native resolutions and don't bring in "enhancements" like upscaling or different video modes.
On the other hand, overclocking may mean a more recent PlayStation 2 or Wii game runs better.
For the record, I don't overclock because that indicates bad engineering - overclocking will always reduce the hardware life because that's what using it beyond its specification does, plus too many people are obsessed with playing "Top Trumps" against each other with their computers and bragging on Reddit about who has the highest FPS, most Ryzen cores or most generous parents donating kidneys to buy their little gamer cherub the latest overpriced and proprietary NVIDIA graphics card each Christmas so they can play "Cybersplatt 4044" or "Starfailed".
Ultimately, the best judge of how well a computing system works is the user - as you yourself have rightly noted with your SNES emulation comment.
Love the video! Please do a review of the new 24.04 LTS from Joshua's on the Orange Pis
I installed on my orange 5 plus and it is working like a charm but only server edition - not desktop one - desktop crashes all the time
Big fan sir ☺️👍
Thanks Lee for this video. I wondered if the difference in speed between the the 4 and 8 gig model is that the voltage requirements on the 8 gig memory chip is higher so it might not be receiving the necessary voltage to let it run a full speed? Well just a thought!
Have a great day!
I've got 2 Pi5s both 4GB one ocs to 3.0 and the other 2.9. I'm glad I didn't get an 8GB. I had the choice.
Just chiming in on my experience with overclocking to 3.0Ghz..Confirmed working ONLY IF YOU over-volt to 5v5A with this pi power supply that i have.. ;) I used the official raspberry-pi USB-C (of course) power supply that only gives 5V-3A ..As many of you already know all of this... but to those who don't.. change the over-volt parameter to 5 NOTHING less or it will not boot... I am using my 960GB Kingston SSD i took apart and used it for the OS.. works!!!! PERFECTLY! ....for me anyways.. that's just me though. ;)
I haven't tried it yet because a lack of free time but I ordered two of the copper water blocks & I am wanting to use my router to mill the flat bottom so the copper only touches the the components that heat up. I'll need to make jigs & do it by hand since I do not have a CnC. Going to need to make at least two jigs because all of the components aren't the same height. *Can the Pi5 be Delidded?* Not to gain the 10-20% cooling but to make everything the same height.
The speed difference is the ram type. There is a different brand ram between 4 and 8 gig and it looks as if the 4 g version is faster in ram tests
nice video post.
I am looking for a board to place inside my car. I want to use realtime object detection to recognise whenever a certain type of car is passing by in front of my car. And I want the board to notify me by 4g/lte sms( no wifi connection so i have to add a gsm/lte/4g module
I am looking at 2 boards:
1. Raspberry pi 5 8Gb with Google Coral USB Accelerator
2. Google Coral Dev Board 4Gb
Which one is the better option?
❤
I use the brass standoffs as feet on my caseless Pi's ... just screw standoffs into standoffs.
I read in a really detailed write up by someone else who discovered this discrepancy that its most likely due to the the 8GB model using a memory chip with higher latency than the 4GB chip; they’re not made by the same manufacturers. (I believe ones Samsung and ones Hynix? Could be misremembering though)
I linked the GitHub, loads more tests there
Interesting about the Pi 4 scores.
Pi 4 scores? No, it was a Pi 5 with 4GB memory against a Pi5 with 8GB.
@@hammockdweller He did try a Pi4 overclock for comparison. It score well.
@@Uniblab8 In this video?
Is the RAM also being cooled on the rpi5 4GB model? Maybe that's what is allowing it to achieve a 10% higher multithread score(same 2.8GHz clock) in geekbench?
he said he is not cooling anything apart the soc, the heatsink you see is just for cpu afik
The temperatures were too low for thermal throttling to occur
@@betag24cn The blow down approach of the original cooling fan might provide secondary cooling to the board and other chips, including RAM. The heat pipe cooler only cools the soc; as the airflow is too far above the board to provide secondary cooling. It's why the early wick away coolers(water cooling or heatpipe) by third parties for GPU's, added an extra fan to blow air at the GPU VRM's after they realised it overheated when the secondary cooling was removed.
@@longdang2681 this heatsink pushes air sideways, not top to bottom, it cant create airflow down there that matters, that only pccurs when it aims down and it has more surface and strength, like a pc cpu cooler fan
@@leepspvideo Maybe for the soc but RAM chips starts to overheat once you start hitting 60+C. Otherwise I can't see how a fixed identically clocked processor can yield results that are 10% apart. It's well known that geekbench are sensitive to RAM speeds. What are your ideas on why an identically clocked 4GB is 10% faster than the 8GB version?
edit: Even the single thread score is 3% faster on the 4GB board, which suggests that the performance difference might be outside of the soc.
Overclocked to same limits and fails using a program. Any tips. If I can’t over lock and use a program how does that help me?
Some Pi’s will Overclock reliably, others won’t at all
Did I won the silicon lottery? with my Rpi5 4GB Geekbench 6 scores were:
Pi 5 4GB
3.0 973 2010
They're just numbers and completely meaningless because ultimately how well a computing system works is decided by the user as to how it feels and how snappy it is.
Playing "Top Trumps" with your computer system, trying to brag about having bigger numbers than everyone else is just for poseurs on social media.
There's a major issue I'm wondering if you've encountered before. It's with the RPi5 8gb running stock RPiOS, fully updated. The problem is with disconnecting peripherals, like USB and microSD. If I insert a USB (brand new SanDisk 3.0, supported) and then use rpi-imager to burn an iso for my x86, it says it's finished and can be removed, but then if I remove it I get an error message saying it wasn't removed properly. Similar thing with a microSD I use as file storage. It plugs in and detects just fine, but when I click the eject button on the toolbar it gives and error and says could not eject. In both cases, lsblk says the device is not mounted, yet still get the error messages. Thanks.
I haven’t experienced this, try asking on the forums
@leepspvideo You're right, that's definitely a forum type question. I appreciate your response

Does it matter if I get the 4gb ram version for a Raspberry Pi AI Kit ?
It’s not something I have used
You never tried increasing the voltage ⚡
...and just a FYI most over clockers use a static fan(s) RPM, just pick a speed where the fan volume is bearable, or if going for max performance set it to maximum RPM
I used over_voltage_delta to increase voltage

That's not a fair comparison (between 8GB and 4GB boards) as the cooling is completely different. Both the fact that the cooler is different and that the NVME drive is in a completely different layout (which will affect the thermal properties of the whole system).
Still very interesting though.
Both didn’t get that hot, neither board would have thermal throttled
I can not overclock my pi atal wonder why
many months ago people complained, it seems it is related to broadcom itself, the company who manufactures the soc
people said they had quality issues
the thing is that nowhere i have seen pi promises overclocking capabilities, so might be broadcom, migth be your power supply but in the end, as long as it works fine at 2.4ghz, should be fine
a shame yoi cant overclock but improvements are not tjat big, so
Its an official pi 5 power supply
@@caleking5876 I tested a hand full of Pi5s and I can say that only few of them can be overclocked and even fewer of them actually get to 3Ghz. So its all your luck
...and to think for about £50 (far less than the cost of even a Pi 5 4GB), you can pick up a used SFF PC with a 3rd or 4th generation Core i5 or i7 CPU in it with at least 4GB RAM, fully cooled and cased, maybe even with a hard disk included that's already clocked at at least 3 GHz.
Much as I love the Raspberry Pi as a concept (I have them all several times over along with Orange / Banana / Nano / Atomic Pi's), this is why it has completely lost direction in pandering to those people that insist it has to be a desktop replacement - when it can't compete in price with used desktop PCs because of the myriads of lemmings flocking to upgrade to Windows 11 and having to dump their old hardware cheap on your favourite auction sites.
It should have stayed as a cheap hobbyist device that sits on electronic workbenches and on school desks providing a cheap programming platform for kids, at £35 it was just the right price and it had a purpose to exist back then - but it's too expensive for what it is now.
Depends what you’re trying to do. I mean overclocking them is pointless, but if you want an SBC that’s going to run some application for a decade, sip power and give you no grief they’re great - though yet to be convinced by the 5, more time needed. Also you can still buy the 3B for its old price, and avoid dongle life. Options are good, I get the device for the application .
I’ve got direct access to UARTS, GPIO, SPI, I2C, I can time sync with PPS, if you use the Pi for what it’s designed for they’re brilliant, built so many small commercial and hobbyist projects around them, all of them would be dongle mania and impossible to integrate into a PCB with a wintel
box.
@@edc1569 I can't argue with anything you've said, points well made.
I would argue that there's already a wide range of devices for electronics projects anyway (and that's a good thing, of course) whether it Pi Pico, Arduino, ESP32 or ESP8266, as well as early Pi's, all of which sip less power than the Pi 5 does.
Again, my criticism isn't of the Pi as a concept but the direction it has been going in in recent years - I don't think a Pi 5 is value for money at all now, it has priced itself out of the "hobbyist workbench" environment now.
