Speed test 2013 iMac vs 2019 iMac

- Опубликовано: 26 авг 2024
- Just bought a new Apple iMac for our kitchen computer. It's about $1800 CDN, a 3.6 GHz quad-core Intel i3 processor, and retina screen.
The problem? It feels just as slow as our old iMac ... a 2013 iMac 2.7 GHz quad-core Intel i5. And that sucks, frankly.
When you buy a new computer after 6 years, you expect that the new one will FEEL FAST. But it didn't.
So I did a side-to-side comparison of real-world tasks ... booting up, logging in, starting a web browser, opening email, and so on.
Here are the results ...
Absolutely love my 2013, I strapped a Samsung T5 to the stand and installed Catalina on it. Mine boots in 27, seconds and the comp just runs beautiful now. Must do IMO
Just got the mid-range 2019 4k iMac. I'm about to do the same with my 500gb Samsung SSD. I've read everywhere that it massively speeds up the computer. Good post. I'm also moving from a 2014 MacBook Air so I'm expecting an upgrade regardless.
Is it even possible to have an os on an external drive?
can you explain this little bit more? how to strap to the stand?
Nick 94 can you please tell me how to strap it to the stand and the late 2013 iMac doesn’t have usbc
Italia311 can you please tell me how to do it
I bought a 2013 iMac a year ago in mint condition and I'm extremely happy with it. It is an i5 and has 16 GB of RAM and a 1 TB hard drive, which is plenty for me. It's extremely responsive, runs very smoothly, and it does everything that I want and need it to.
Do u game on it
@@yourmummy6582 No, I'm not a gamer.
what os
could u game on it @@jrwheeler81
@@jrwheeler81can this be used as a monitor only and how’s the screen quality? Is it as good as retina?
i was about to order a new imac cause my 2013 was taking as long as yours to boot up but i installed a 2TB NVMe SSD and now it works great. i also upgraded my ram to 32 GBs
Thank u for this comment
They are really cheap 409 on amazon and im really looking foward to getting one ! This comment is like sent byt an angel because i want the absolute beat for my imac. Does the boot up time significantly decrease? Or does the upgrade speed up processing of open tabs etc?
IMACs are AMAZING. I am still on a 2013 with SSD and it is still awesome.
Is it still good I have ordered one today
@@jjranson6761 I'm considering buying one, what are you thoughts about this iMac?
@@janm9774 it is quite good I use photoshop on it and sometimes it can be a little slow but a lot of the time it is good
@Christian Burris me too i have monterey on the IMac and it run perfekt
I have a similar tale to tell. I too have a 2013 iMac. It was the top one of the 3 different versions. It came with an i7, a fusion drive comprising of a 128Gb blade SSD & 3TB HD. Upon getting it I added another 16Gb of RAM to the 8Gb it came with. I have been very happy with this machine. Eventually the 3TB HD failed so I switched to booting it from an external thunderbolt 1 SSD. So I’m used to a bit quicker disk access. Fast forward to 2021 and Apple silicon is putting an end to BOOTCAMP so I splurge on what will be the last Intel iMac 27. Again I went for the top model. I added a 1TB SSD & maxed out the GPU. Cost about the same number of dollars as the last one. So actually cheaper in real terms. I’ve also upped the RAM to 32GB of 3rd party memory. After all this, in terms of everyday use, there is no difference in user experience. The boot time is effectively the same. Big Sur if anything feels more sluggish than Catalina. It’s all a bit underwhelming really. So I feel for you man. All these benchmarks count for nothing if you don’t improve the user experience. Im surprised I don’t see more disappointed upgraders maybe everyone waited for Apple Silicon?
i have a 2013 late imac. the one you have, so yeah 1TB hard drive 2,7GHz 4-core i5 and intel iris pro 5200 and its still heating.
Wow I can’t imagine having a spinning hard drive now. Even fusion drives are not great. My iMac with SSD boots up in about 12-15 seconds and is ready to open programs up right away with no lag
Me neither. I installed SSDs in my 2011 MacBook Pro and 2012 iMac.
My 2015 MacBook Pro already had an SSD, as well as my 2020 ASUS laptop.
The issue are the slow 5400 rpm drives. My family has 2 iMacs (2011 i5 with 8gb of ram and a 1tb hdd and a 2017 with an i5, 8gb of ram and a 1tb hdd) and the new one actually runs slower because of OS X Catalina. Which slowed it down to a crawl. Because the 2011s came with a 7200 rpm hdd, my iMac which cost a 6th of the price boots and runs faster.
I own a late 2013 imac and it works pretty good with el captain and 3.4ghz proc and I5; thanks for this video
My iMac 2013 i5 boots up in 15 seconds with a T5 1TB SSD hooked via USB. Got it for $120 from Office Depot. Best and easiest upgrade I've ever done. I won't upgrade until the new M1 30" come out.
How do you install t5 sdd?
still the 2013 imac runs faster than many 2020 office Pcs
I read your article online. Does this also affect video editing speeds and other demanding applications?
Kinda old video, but used imacs are crazily cheap. You can get some high end models of 2012 for 500$ which cost a fortune back then and are still better than the entry models of nowdays.
Startup speeds are varied mostly by storage types. Since it is an HDD, that will cause a super slow start up. Fusion drives will make it slightly faster but ssd will cause startups to be at least 4 times faster. So the main difference will be seen on a metal test
i have a 2017 iMac with HDD, wil i be able to upgrade it with SSD
@@nitinbhat you can but they are a pain to go through. They also have a pre-installed heat sync attached to it. So you may want to have a professional install it for you. Due to the labor being risky
@@liammasias7029 ok, thank you for the clarification :-)
@@nitinbhatyou can use external drive
@@BillyBawbCEC yup, I did the same around 6 months back, it feels like a new computer now, super fast at least from how it was earlier with the HDD. Wish I knew this earlier, I used the iMac for almost 6 years with the HDD and it was a painfully slow system.
Was there any chance Spotlight was indexing the full hard drive and thereby made it slower?
In all honesty, you didn't really need a new computer, well not to justify an i3 $1,800 machine. The 2014 model you have is still quite a good machine. What I would have done is take it somewhere qualified (unless you feel confident doing it yourself) where they can remove the screen and install an SSD. This is exactly why apple gets a bad wrap. I recommend at least exchanging, and buying one with no spinning drive at all. If cost is an issue, Costco sells (at least where I live) 27" fusion models for around $1,800 with pretty good specs.
we returned the new iMac :-)
FYI I got one with a Fusion drive and am having the exact same issue where it is as slow as my 2011 (& didn't realize until too long to return!). So Fusion drive just as bad.
Hello, I have an Imac 27 late2009. HDD 7200, 12GB ram, 60s for logging.
6 year newer machine yeah but tech that runs both computers is basically the same
My 2004 and 2012 iMacs restarted in 45 seconds. My 2019 takes about 4 minutes. I returned it for one with better specifications and it is still 4 minutes to reboot. Also freezes after software updates and must be shut down and restarted with the power button. I can’t believe no body talks about how bad these things became after Steve Jobs died. I’m not so confident my 2019 iMac will last over ten years like my other two did working perfectly the entire time. I’m curious how the M1 iMacs perform.
You have a kindred soul here, SJ. That makes just the 2 of us. I’ve been preaching to deaf ears about the demise of Apple since Steve Jobs passed for years now. Tim Cook? Please. I was just taught how great Apple was by a new friend who was an Apple Genius in mid-2010. I dumped my Dell laptop immediately and bought a refurbished 2009 27” iMac in November 2010. What happens? Jobs dies October 2011. Damn it! Then what do we get? Timmy! Damn it!
I sold that iMac in late 2014 to upgrade to a late 2013 27” iMac i7 (which I still use). Tried to future proof for a long time.
A-scared to buy anything newer with Apple’s continued loss of class, reputation and leadership in the marketplace. GiddyUp…
Thank! I am glad that I read it before I was just about to upgrade my later 2012 imac to a 2019 imac. Even if we can use an external SDD to improve old imac, what about the compatibility with new Mac OS?
2014 is the oldest you can go in the iMac to update to Big Sur.
Both the i3-8100B and the i5-4570R are very comparable, including 65 watts TDP. The move to DDR4 should have brought some improvement -- if the motherboard exploited it. This was also that period where Intel was "sparing" on thread count, in both instances. Sometimes the move to i7 makes a lot of difference.
Go get a SSD for the 2013 imac and return the new 2019 imac. It feels much more better
Tony thanks bro I’m tryna to use Adobe in that
The i3 cpu is a bottleneck though.
@@kalijasin No it really isn't. You'd be surprised how good the new i3s are.
My software runs a lot better on my 2019. I have a few older Macs and boot up time is about the same unless you get a SSD.
I don't think I've ever seen iMacs take this long to boot. My 2013 one does it in probably 10-20 seconds. I am guessing this has to do with the hard drive.
I hired a technician to upgrade my iMac from 8GB to 16GB and had an internal 1TB Samsung SSD installed. My iMac boots up fast but it operates slow or crashes sometimes when I use Adobe Photoshop or Illustrator. One Adobe rep said it's the Intel Iris Pro 1538MB causing the issue and I will need to upgrade to a new iMac. Is there a way to get around this without needing to buy a new Mac?
Wow the trick with the external SSD works! My iMac 2013 8GB RAM was sluggish and even slower after the Catalina update. It took about 3 minutes to boot and about 5 minutes to start up programs like Photoshop or InDesign. With a Carbon Copy of my HD to an external Samsung T5 the systems is faster than it ever was: booting in seconds, Photoshop an InDesign in seconds.
Does time machine work with the T5? Mine stalled
@@mariephotography6251 yeah, I cloned my OSX on that T5 disk and booted from that disk and everything runs very fast now
Patrick Hochstenbach I did too, but when I try to do a time machine backup to another external drive, it just freezes
@@mariephotography6251 in my setup I have the OSX on the T5 , the internal disk of the Mac is just there (I don't use it anymore but also don't delete it) and I also have another external drive on which I put time
machine backups. I don't know exactly why is doesn't work for you ..:-/
Patrick Hochstenbach yeah, I didn’t clone mine; I did a fresh install and migrated everything over..
Damn that takes ages to boot up..
God that boot sequence!😳
Its 2020 and i have fan accounts and like making edit but my asus is slow so this video has rlly bosted me to get a 2013 imac tysm
I don’t have a desktop so I don’t know what to compare except my iPhone
So frustrated with my 2019. My husband refuses to use it because it has been so slow since the day we got it.
I finally got fed up and called Apple. They wasted a week of my time bouncing me from person to person, running diagnostics, admitting it is very slow, but saying things look fine.
Eventually someone told me that the spinning drive can’t handle OS newer than 10!!!
After over a decade of being an Apple person, I’m disgusted they released this and won’t admit their mistake. Absolute waste of money.
Word of advice add an ssd lol.
That is ... kinda the point of the video :-)
Whats an ssd
They want a fortune for it though.
God Slayer Solid State Drive. A faster hard drive than what’s in it.
How do you do that
Damn that is painfully slow. My 2017 2TB fusion drive (has 128gb nvme) 5K imac takes 31 seconds to boot up. It’s getting upgraded soon to a 1TB nvme soon.
Guess makes me glad I waited for the new m1 to come out. I was going to buy a last gen in 2020.
how that boot in 106sec it is slow because my old MacBook 2008 boot fast and i have on it mac os catalina
The Safari test wasn't done properly. You seem to have Safari and iTunes as Startup items on the old iMac. Both apps are active and already opened before the test. You can tell that by the black dot under the icons in the dock. Otherwise you maybe forgot to quit the apps last time before you turned the iMac off. Mac OS remembers that and starts the apps again next time you turn the computer on. You should use other processor intensive apps and tasks also for the test.
In the end the results were pretty expected with these simple tests. Although the new iMac has a faster quad-core i3 with 6 MB cache, base speed of 3.6 GHz and faster memory and bus speed it will appear only slightly faster in simple apps lika Mail and Safari that stress the processor only for short moments. In such moments your old iMac with quad-core i5 with 4 MB cache and base speed of 2.7 GHz boosts up to 3.2 GHz and make the new iMac appear only slightly faster. The old iMac can't though sustain the boost speed and under heavy load when all the cores are needed may go back down to base speed to not overheat. The new iMac on the other hand can continue to work with the higher base speed and get heavy tasks done faster. That's why you should for example do some video or audio encoding to really compare the two iMacs.
If you had tested the GPU you had noticed a big difference too. Radeon Pro 555X is much faster than Intel Iris Pro 5200, 2-4 times faster. So if you are a casual gamer or use other apps that take advantage of the GPU you notice a big difference. Otherwise you didn't really need a new iMac for just web browsing and mailing. Your old iMac can still handle that. You should also wait for the next iMac upgrade comin soon, with AMD Navi GPUs. I myself am still using my 21.5" iMac 2011 with Radeon 6750M 512 MB for both gaming and other stuff, but mine has a 7200 rpm HDD. :)
Nope, no startup items
Bc of the 5400 RPM hard drive that they also used in the 2013 version
You can literally see that safari and iTunes have a black dot underneath them from the second the 2013 logs on….and you can see they don’t do the little bouncing effect when you click on them on the 2013 iMac AND it says safari in the top left corner and not finder…those apps were already open at startup…test is inaccurate
My Dog step on a bee.
Found a used 27'' iMac from late 2013 for 500 bucks. Do you reckon it's a good deal?
Specs:
3,2 GHz Quad-Core Intel i5
8 GB 1600 MHz DDR3
NVIDIA GeForce GTX 675MX 1 GB
1 TB hdd
Cool be. Especially if you add a solid--state drive for the operating system
Just purchased for $510: late 2013 iMac 27” 3.5ghz, , 1tb hdd, 16gb ram, and (MOST importantly) the GTX 780m 4gb gpu - this gpu scored higher Unigine Heaven benchmarks than all MacBooks up to the 2019 15” (560x), and surprisingly even beat out the 2015 5k 27” iMac (m395x). For another ~$150, upgraded to 32gb ram and 1tb NVMe ssd, while holding the 1tb hdd as a secondary internal drive. Cannot stress how much of a difference the gpu with 4gb ram makes. 4K video editing and Fortnite run BUTTERY 🧈 smooth! Altogether, for ~$650!
@@WinningTime328 nice!
Jean Lee where did you get it from?
Not a good deal!
I remember my 2009 Imac when pressing start button loading up and being on the desktop within 30secs my 2013 imac i can go make a cup of tea and read the paper before it loads. Even windows on bootcamp loads far quicker
In a remarkable turn of events, machines in 2019 are slow when using 5400rpm hard disks. Get both machines SSD's, forget fusion drives.
Safari test was unfair, since the program was not fully closed/had the 'open' dot on the 2013 model.
Hi, can I play Sims 4 in iMac 2013? Thanks!
Do you guys still reccomend me today to buy a imac 2013? In 2021. I dont have a lot money but i want so hard a imac :((
I don't. I think you will be better served saving up for an M1 iMac
I've got a 2010 base level mac and it boots up in 52 seconds!
Did you upgrade it to ssd?
LOL
I’ve just put an ssd and ram upgrade in my 2009 27” imac and it boots in 24 seconds now, apps load much quicker and i’ve forgotten what the beach ball looks like!
I highly suggest, buying a refurbished Mac, waiting a while, saving up a bit more, and getting an i7 instead of an i3. I would never consider an i3.
I purchased a 2013 27" with an i7, 32 GB of RAM, and a 3TB fusion drive (recently updated to a 2 TB SSD) a year ago for $750.00. and it constantly run likes a *dream* the specs matter much more then the year.
Still happy with it? One year later?
Does it run on the newest version?
What's the max ram possible for upgrading?
my iMac late 2013 21.5 with a samsung evo ssd boots in 14 seconds ...
Nikos is it an external drive or have you taken apart you computer and added it can you please tell me as I would like to do the same
Ya when I bought my iMac 27 i7 I had to return it and sent for SSD storage, night and day difference, never tried the Fusion drive, how is it?
I think it's a good option to get speed but also quite a bit of cheap storage
fusion drives adapts over time ..had one in a MacBook late 2012 and it got faster overtime but not right away..
Can anyone answer me. Does imac 2013 support obs studio?
Does the 2013 come with iphoto preinstalled or is it on a disc?
pre-installed, and will update to Photos
@@johnkoetsier Thank you!
Mine has become very slow after installing the new updates .. takes 2’minutes to load
Babu B India you really should install an SSD in it then. It will basically be as fast as a 2019 iMac (if you have the 2013 iMac).
Swapping the HDD with the SSD makes it SO FAST. It is compatible with Catalina, which will get security updates for at least 2 years. 2 years extra life? Awesome! I just did it literally today. It was taking my computer 10 whole minutes to load (I think the drive was failing). It takes maybe 1 or 2 hours tops. Ifixit has a guide and there’s also one on RUclips
He pal. im about to purchase a used 2013 iMac. How can i get the SSD you talk about? Can i physically buy it in store ? Hopig for your response. Im new to this thing tho. Thank you.
i just tested the same on my new 2019 mac and they did not take anywhere near that long.
good to hear! could be a different set-up, I guess.
best macos for imac 21,5 late 2013?
Mac os sierra
My 2013 is a shredder booting off the Samsung T7. 30 second boot.
Hard drive read/write speeds are what’s important here. A regular ol’ spinny hard drive (which is in both of your iMac) will be slow in any Mac regardless of how new the Mac is.
If you went for an iMac with a Fusion Drive or a full-blown SSD you’d see the speed increase throughout macOS by a couple times, like you want.
Also the 2019 iMac is a much better Mac all around comparing to your 2013 iMac.
You can attempt to replace the internal hard drive for an SSD or an nVME SSD. There’s plenty of videos here on RUclips on exactly how to do this. Or you can bring it in to a 3rd party repairer to swap out the drive.
what storage drives do the two imacs have?
Both standard built-in SSDs
Newer is better and you will see difference when playing games, editing video or doing anythin that needs processing/graphic power. Also, take into account that newer has much better screen resolution.
I am still using my late 2013 iMac and I am satisfied of it as it is.
when it comes to performing task both feel super irritating
The rotational HD just kills the Apple experience :(
Agree. I've been on laptops for years and going back to old-style disk drives is just awful

FYI, I translate and QC a lot of subtitle files and sometimes when translating/QCing variety shows (usually span between 60-90 minutes with like 2000 lines on average, done on a cloud software), my current device tends to lag a lot. My current asus vivobook has 4gb RAM and 128GB SSD. So that's why I've been eyeing used imac. Thanks!
Sorry but.. What is new??
test with ssd please
g king next time!
Ouch I still can't believe Apple still uses mechanical drives hybrid or otherwise. Just timed my 13" 2012 MBP to boot into the OS using a 6-year-old Crucial M500 SSD; 27 seconds. Get rid of the 2019 iMac and install an SSD such as a Samsung 860 Evo and be done with it. Or if you insist on new iMac, get a basic 256GB SSD config, and use a NAS at home with 8TB HDDs configured in raid1 for redundancy.
yes but i needed completely to downgrade my mac because after High Sierra update in MOJAVE the Cuda Driver of my Imac14,2(late2013) 27" Geforce GT 755m does not work anymore... and thats a shame for apple !
Ssd makes a big different
Hard drives are hard drives no matter when they are from. An SSD from 2013 is going to be much faster than a hard drive from 2021. The problem with iMacs is the pre 2015 models have limited ram built in. 2015 on with the ram ports available to upgrade means the memory needed for newer update versions is there. Anything pre 2015 is left with the older ios systems, not supported...and almost useless. 2013 with 500 gb SSd...but 8 gb ram = El Capitan...no system update support...trouble trouble trouble. About the only option is an external ram option. I don't know why anyone would even want a hard drive anymore. Used Imacs with SSD several years old are a bargain and will give years of reliable, much faster service than comparable new hard drive units.
i just bought late 2013 imac 21 inch. The mac os is mojave. Should i upgrade to Catalina?
Yes.....
If you have an SSD yes. If you don’t, get one, and then upgrade. Be sure to back up files on the cloud :)
They seem the same
1800 bucks for a i3....
but Jobs said that they don't ship junk!!
My 2012 hp aio takes only 20 sec to boot lol and that too having an hdd
Hmmm just by looking I can’t see any difference in the design still shocking there is no SSD
There"s an SSD option.
Hard drives shouldn’t even be options anymore
Fusion drives suck. I bought a perfect condition used 2013 27" iMac with the 3.5Ghz i7 and 16gb RAM (factory original). I removed the 3TB fusion drive and installed a 1TB SSD and it makes a HUUUGE difference. I'll never need more storage so 1TB is plenty. I'm debating whether to update my RAM to 32GB or buy the latest iMac, but not if the new one has a Fusion drive.
You need to reformat your drives.They are never that slow. 15 to 19 seconds at most. Trust me there was an update issue that incorrectly reformatted your drives on both machines. You can find the repair instructions online at apple.
i3 intel cpus are really low-end cpus. They are only good for use on like a chrome-book or lightweight linux distro machine.
Lol he has a piece of tape on the camera
It’s about the HD. get fusion or better still SSD. Even on the old one you can have an external SSD booting OS. makes a hell of a difference.
2013 imac is better than 2014,15,16,17,18,19,20 how is that possible all it needed was an upgrade to 5k
is a dual i5 core better than a quad i3 core?
I boot my 2013 iMac from an external SSD. Boots in 20 seconds.
You can’t compare an old iMac with 4 profiles with a newer one with one two profiles. It makes a huge difference
What do you mean with profiles?
I have a iMac 2017 32 gb ram and 1tb fusion and boots much faster than yours does. Love my fision drive on my iMac.
you are actually comparing a 2019 i3 to a 2012 i5 and wondering why they run a out the same?? only a 2019 i5 should have been noticeably faster really, and an i7 even more so...
I guess you have zero knowledge about HW.
I had lenovo laptop and is more faster than my imac 2013 hdd, I'm gonna put ssd I think, because it takes many time to do every thing.
Is this a joke ,fancied getting an old iMac , don't think I will bother now .An old 486 pc is faster to boot and open stuff .Must be even worse when multi tasking
you need a ssd
3:50, the winner is not the iMac 2013, because the safari app was already opened.
My 2009 Mac mini with 1.8 duo core and 2 giga ram opens way faster wtf?
I just swapped the HDD with an SSD and the 2013 iMac is blazing fast. It’s even on Catalina. SSD is the most important thing - NEVER EVER get a computer that’s based on an HDD.
I bet you’ve already done what you’re gonna do, but tbh, if you have a budget for a new one, I’d just replace the 2019 one with a new one with an SSD. Sure, the 2013 will get 2 more years of life (Catalina is the last OS it’s gonna get and it’ll get security patches for 2 more years) with an SSD, but a 2019 with an SSD can get like 10.
All you need is mac memory cards to boost you speed up, I went from 8GB to 24Gb and I can now browse the net with multiple browsers and no beach ball.
Der aus dem Jahr 2013 hat eine 5400rpm hdd und der 2020 eine NVME M SSD oder nur eine normale ssd kein Wunder das der 2020 schneller startet
Both are slower than win
Wtf 90sec
My potato celereon is more way faster
Celeron! Been a while since I've heard that :-)
Unfair
Damn! My 27" late 2012 model is faster than both of these. It has the standard hdd in it, but i have upgraded the ram to 32gb, so that's probably why. Mad how new models are not a lot faster than older models.
Hello friend, can you please help me? I dont have a big budget but i really want to have a imac. Do you reccomend me to buy a imac 2012/2013? Today in 2021? Is that worth the money or is it a big risk? I only want to use it for daily things like microsoft word and pinterest and google and youtube stuff like that.

Sorry- But I do not think your non-scientific test is worth much. Its not Apples to Apples (pun-intended) You should have run Geekbench. (I've only owned Macs since 1985, so I guess I don't know much about Macs)
Yis mush U-no the rules
So it’s a con
This testing is a joke! A traditional HDD has an "Average Statistical Life is ABOUT 5 Years". Apple's predilection is to also use SATA 2 / 5400 RPM drives in their computers, which are DOG SLOW to start off with. Just running your test like this proves NOTHING. I guarantee you with a NEW SATA3/7200 HDD or SSD, the 2019 will be much faster than the 2013 for computational workloads and should in general be in loading apps in general, but you might be talking 1-2 secs loading difference. I have seen this LOOOOONG macOS load time, and its a failing HDD, due to "Lifespan" and likely has read/write errors. Run DriveDx on both of them to compare Apples to Apples on the HDD's and see their health status. I repeat and replace drives and RAM on 2013 to 2019 iMac all the time, and your testing is very much unbalanced in it's presentation.
