Intel Arc A770: Performance Comparison of PCIE 3.0 vs PCIE 4.0 - Is PCIE4 really necessary?

- Welcome back to another video people ;) this time we will be testing if PCIE4 does give any performance boost on Intel Arc A770...
A few words about PCIE3 and PCIE4... PCIe is the primary interface used to connect the graphics card to the motherboard. PCIe 3.0 was introduced in 2010 and offered a bandwidth of 8GT/s per lane. PCIe 4.0 was released in 2017 and increased the bandwidth to 16GT/s per lane. This means that PCIe 4.0 has twice the bandwidth of PCIe 3.0, making it a potential game-changer for graphics card performance.
But does it really?!
To test the performance difference of PCIE3 and PCIE4 on the Intel Arc A770 graphics card, I ran two specific benchmark tests and a game.
The results of the benchmark tests were as expected... On PCIe 3.0, the Intel Arc A770 delivered excellent gaming performance, with smooth frame time in Returnal with high-quality graphics. However, when I switched to PCIe 4.0, the performance only increased by a 1-2% so replacing your AMD lets say PCIE3 board with a PCIE4 won't actually be a good idea in my opinion and same goes for intel (new boards have PCIE4 anyways).
Save the money and use it to upgrade something else ;)

PCIE3 Score (better)?: gcdnb.pbrd.co/...
TEST BENCH SPECS:
GPU: Intel Arc A770 Limited Edition 16GB
CPU: AMD Ryzen 5950x - REBAR ON
RAM: 2x16 3600CL16 @ 3800CL16
MB: x570 Gigabyte Aorus Extreme
this is exactly what I was looking for. so many channels only testing on the latest hardware not thinking of the normal population.
Next video should also be helpful ;)
There's even "modern" hardware that's still 3.0, like a Ryzen 5 5500 for example that came out in 2022 and only supports 3.0 (although it still supports RE-BAR
Although there's also older hardware that supports 4.0 like the Ryzen 3000 series from 2019 (dunno if they support RE-BAR tho, edit: yep Ryzen 3000 does as well)
So AV1 recording via Intel Arc Control Panel got better? Next video will be recorded with OBS and I might do a performance comparison again this time also with A380 as 2nd GPU recording?
Yes! But very interesting would be also how to encrease the fps in Handbrake when encoding h265 or AV1
just putting it out there for anyone wondering.
i have a PCIe Gen 4 motherboard, paired with a Gen 3 riser cable (because of older gen GPU), but now i paired with the Arc A770.
Stability on every startup is vague to say the least, i have to fiddle at least 30 min to get a display output and/or completely reset BIOS and force set PCIe setting to Gen 3 because of this riser.
im getting a Gen 4 riser cable to see if the problem finally goes away and give me more stability and less headache.
I got a PCIE4 riser on a PCIE4 MB and have to set it to PCIE3 since it doesnt work. Must be something else then with the riser as I have it set at 3 and it works fine. On pcie4 I dont get any display output.
Very interesting. Im using an A770 LE for quite a while now with pcie3, combined with an i5 10600 non k on 1440p and im very very happy with it. Actually i have much less issues with the Intel card than i had with the previous ones driver. So far so good and comparing prices when i got it and even now...i dont see anything here that has a better price / performance and is 1440p capable
If Intel keeps updating the drivers we'll have a very future proof card thanks to its 16gb, unlike Nvidia charging 400 bucks for a card with 8gb
im running the same setup but i have the k sku and its all on water and im pushing the gpu to 2750ish and its the 16gb version and the cpu is running at 5.1ghz and the drivers just keep getting better.
@@MegaLoquendo2000 Tbf Nvidia has really good support for games and really good drivers, but they're charging thousands of dollars for a card with the same potential. The drivers keep getting better with Intels card and I can play all the titles at high settings with my A770 LE 16GB. But my CPU is bottle necking a bit I think (9600K @ 5Ghz).I previously had 1070 8GB which wasn't a bad card.
Honestly despite my system having a outdated xeon w 2135 I still think even with pcie 3.0 and no resizable bar these cards can still work great and by the looks of it the main advantages is gonna be with drivers in the future.
I will make a video once I come back to MOD rebar into older systems (it just works). You need it to get the optimal experience with better frametimes. Tested on 7700k system and 4690k.
@@graphicarc Dang I hope so that would be great.
@@graphicarc 4th gen Intel test? Wow I'm interested in that too. It would open the door to so many potential customers that Intel might have ignored on their initial launch of the product saying only 10th gen with ReBar can use the Arc GPU
How is ARC performance impacted when limited to just 8 or 4 PCIE 4.0 lanes? I'm deciding between the Ryzen 7600 CPU and the 8600g CPU. The only reason the 8600g is in the running is to use the integrated RDNA 4 GPU for VR apps the ARC won't run, and it doesn't have a full 16 lane PCIE bus for dedicated GPUs.
this is really good too know i have a 4.0 board but a 3.0 cpu, then i can first buy the gpu and anytime later a better cpu :)
thanks for the video
btw. nice accent :)
Cool vid man
yes
I have ARC A750 running on 10700k. I keep getting errors about the driver only working on 11th gen or newer but it has been working great. I have resizable bar on my motherboard so it appears that it wants PCI 4.0. Anyway, no problems and never any errors or glitches. Super happy with my card.
Huh interesting.. did you ddu when installing new drivers? Rebar works with pcie3? Not much of a difference between the two anyways to be wasting more money on cpu upgrade. 10700k is a beast especially when OC ;)
@@graphicarc Yes.. Z490 board supports resizable bar.
Can you make a video that clearly establishes the cpu overhead that the arc cards require? When using a midrange cpu like the 3600 with an arc a750 the performance tanks sometimes in cpu intensive scenes. Mind you, the cpu is not being used 100% so it's not a bottleneck for sure but some kind of driver overhead issue
I actually do have one 3600x here and I will do a test but I do not have A750 (yet). Just waiting for one motherboard to come as I need to fix one B350 Strix and will use that for recording.
for what game? generally, the a750 will be the limiting factor and not the 3600.
@@user-wq9mw2xz3j some games explicitly hate zen2 architecture and run on it like on Intel 4th gen i7
I'm torn between gtx 1080ti and arc a750, They are the same price in my market and a750 is new unused
What do you recommend 🌹
While 1080ti will give you better performance and drivers are more optimized... It will also use more W, might not work on newer games (Alan wake 2 (got fixed tho)). Be prepared to also open it up and replace thermal pads and paste. I would probably go for an A750 ... If you got rebar support etc.
@@graphicarc I have an R5 5600 and B450 steel legend, Motherboard have the rebar option but it support pci gen 3, Will there be a problem?
can you give me a GPU that is close in performance to the A750? To know what performance I will get from it
Thank you so much bro🌹🌹
RX 6600 might be the other option? With pcie3 you will lose only a few frames "if". Might not be as good in AI generation as A750 though.
@@graphicarc
Rx 6600 It has the same price as the Arc A750 Do they have the same performance?
Should be around the same performance as A750?
I think I'm gonna buy the A770 for AV1 and quicksync and sell my 1080ti, its been a good 7yrs
1080ti still trustworthy ;) but yeah no AV1 support which is really good eapecially if you stream and upload speed isnt where you want it to be
Nice 👍
Graphic, i have a mobo Asus A520M and ryzen 5 5500. That config can support a arc 750 or 770 or dont? I dont now about rebar, newbie in conifguration. Whats about u said that config and the arcs or better think use a nvidia or amd? Thanks
It dupports intel arc just fine afaik :) update bios and check if it supports 4g decoding and rebar.
В будущем будет ли приемущество в сторону pci 4.0 для a770?
There is already some benefit if 2-3 fps can be called that. Not sure what future will bring tho.
I'm thinking of buying a750. So should I go for b450 (pcie gen 3) or spend some more money on b550 (pcie gen 4). I really want to spend as low as possible so that I can spend more on something else.
I would rather pay 20-30$ more for b550 then b450? Unless you can find a 20-30$ used deal on it..
@@graphicarc I found the 'Gigabyte B550M Aorus Elite AMD Micro ATX Motherboard (China Version)' for 120 usd. I'm thinking to go for this one paired with a750 and a r5 5600
Is the latest driver 4146 "Dead Space Remake" still unplayable?
ua-cam.com/users/shortsKbOyz9W3aUU - sums it up :)
I have i3 9100f and h310 motherboard which have pcie 3 and have re size bar in bois. Should I buy this graphics card or go for nvidia
Not much difference from PCIE3 to PCIE4 so up to you, which gpu you want to get? Mot sure how a770 plays with 9100f tho.
@@graphicarc I am looking for Arc A750 which is much cheaper than rtx 3060-12gb
My cpu is 5600g,should i go for arc a750?
If for 1080p then yes, otherwise try to grab A770 16gb if you going with intel and 1440p.
@@graphicarc ok thanks man ❤️
I have Ryzen 5 5600G cpu. Should I go for arc a770 or rx 7600 gpu? My psu is Corsair CV550w.
7600 is 8GB so if you are gaming at 1080p ... Go for it :) higher resolutions might have a problem in the future.
@@graphicarc another question. Can I use arc a770 with a Corsair cv550w psu?
I have 9100f which is a 9th gen CPU. I don't think my MoBo has fast access memory/ resizible bar.
9th gen should be compatible well depends on the MB.
I got the r7 5700x and 32gb ram, somehow I messed up the installation of intels driver on the A750! I can get bios and windows loading up, then when windows is on, writing the password wont come up, I resized bar and put that 4g on, somehow it only shows a complete black screen!
Have you fixed this? If not try to boot into safemode with internet and ddu the driver?
@@graphicarc yes, its the simplest of ways to do it!while the pc is on, you simply pull out the hdmi from the gpu, then put it back on!1½ seconds later the picture is on!didnt know the gpu only works with igpu intel cpus or the expensive 7xxx series from amd to render in premiere pro!
Brother is 11400f good for Arc A750 oc version ??
Go for it ;) should be perfectly fine
have the same specs, everything works perfeclty, go for it.
Got Gen3. but don't have Rebar on me MB. so i will not get ARC yet.
Having SAM (bar) is the thing that you really need yeah.. I personally also wouldn't get this GPU if you don't have this option.
Resizable Bar can be activated almost on every UEFI motherboard.
To add it look for "ReBarUEFI" and you're gonna need to patch your UEFI.
@@graphicarc It's not in the bios. so no can't use it 😞
@@hombrepepega3472 Well not on mine. it can not. because it does not have it. and it's a UEFI MB.
it doesn't need pcie 4.0 but it DOES need rebar
True. Been happy on my 12600k with pcie4 riser that has to be set to PCIE3.
spiderman remasterd is the right test subject - At least 8GB VRAM on Very High & CPU intensive game (RAM bandwith, PCIE bandwith). Does your MB allow PCIE2 or x8 to further limit PCIE bus? 😁 rx7600, 4060ti cards with PCIE x8 have severe FPS drop when using PCIE3 instead of PCIE4 🤣 and RT on = stuttering, because additional need of more than 2,3GB of VRAM
I have mine in a PCI-E Gen 5 slot on my asrock motherboard. I also, have 2 pci-e gen 4 slots as well. 😁
