Radeon RX 480 vs Geforce GTX 970: CPU Scaling

[Sweepr]

Most reviews used CPUs that are more expensive than the VGA itself and might not reflect what Radeon RX 480's target audience actually owns. Pure PC tested AMD/NVIDIA CPU scaling with Core i3, i5 and i7.

Seems like the old 2500k can handle it fine...

Different games (expect RotTR which runs great on all CPUs), and we all know Core i5 does well so nothing new.

Considering 47.59% gamers are still on dual-cores according to Steam Survey, which includes Core i3 and slower Pentium/Celeron CPUs, it's a shame more reviewers didn't test this new mainstream card with <$200 processors.

$200 card... looks good to me. The RX 480 AIB cards will perform much better as well, will most likely surpass the 970 and cost much less.

Looks like AMD still has more cpu overhead, at least in Dx 11 games. 480 gets soundly trounced by the 970 with an i3.

Well my post brought more testing results, which I thought was the point of the thread. Or is this just another thread for you bash to AMD in?

Computerbase testing is the best out there right now, purepc.pl has always been Nvidia biased, their tests always have AMD a few % slower than other sites, not to mention the settings they use are near unplayable.

Here is a guy running it @ 1300 under 100watts using a 7870k APU:

XFX RX480 8GB 1300/8500mhz
7870k 4.5 GHZ APU
2400mhz 16gb ares RAM
Corsair CS650M
Asus A88XM-E mobo
240GB Team EVO SSD
2TB 7200rpm HDD

He said he'd post some game results but even the APU doesn't appear to be holding him back so far.

It would get worse with Pentium/Celeron and older Core i3. People with these CPUs need to have that in mind.

I'm waiting for game results then, because only a few hours before reviews you told this card was at 45-50° C under load and never throttled, and we all know how that turned out.

Also, 4.5 GHz 2M/4C A10-7870K is one the fastest AMD APUs, so it should fare better than many dual-cores people are using.

Nice results and on an APU too! :thumbsup: I'll be picking up a 480 when the AIB boards come out.

Looking at your sig I doubt you'd even have the horsepower for the 970. I can see why your concerned. I'd suggest a full build before you consider a gpu upgrade.

That was my 2006 rig. Time to update sig.

GPU-Z defaults to a low sensor refresh rate of 2.5 seconds, which may not be good for measuring power use and voltages on video cards that are "peaky"?

 

[SPBHM]

it's a shame the 970 have the memory issues/limitations because it would be a great card for the used market, specially for people with slower CPUs, the Crysis 3 result is a huge win for the 970.

Sorry for only posting results that I had seen? How many false leaks did you post about?


Computerbase was able to undervolt their card and get it to be faster, cooler and no throttling.

https://www.computerbase.de/2016-06...el_potenzial_fuer_undervoltage_bei_der_rx_480

Also, unlike the $100 "premium" 1080 FE cooler (https://www.computerbase.de/2016-05/geforce-gtx-1080-test/6/) the 480 didn't throttle after 20 minutes: https://www.computerbase.de/2016-06/radeon-rx-480-test/5/

The maximum achievable 1,886 MHz, the GeForce GTX 1080 Founders Edition are more of a theoretical value: In games you never see this clock. There, the highest ever measured frequency was during the tests 1,835 MHz, but was also the clock after a few seconds history. In demanding titles 1.785 MHz has finally placed as the highest, realistic clock out.

The 480 is only ever throttling due to power draw being set too high, not thermals like the 1080 FE.

Also, 4.5 GHz 2M/4C A10-7870K is one the fastest AMD APUs, so it should fare better than many dual-cores people are using.

So now APUs are faster than i3s? Guess people should recommend them over Intel for budget builds then.

I thought we were trying to look at CPU scaling here, but it seems like you've already made your mind up since you attack me every time I post information.

Did he post false leaks or just data that does not fit your agenda?

No, he created a thread where the only purpose to was bash a company and a product, control the content of the posts, and basically flame an entire forum. That's all. Real winner of a thread we have here. Such great posts... But that's OK with you right?

 

[nurturedhate]

Please mods just lock garbage flame threads like this and properly deal with the OP in some more permanent manner. Would go a long way to making this place more respected.

Yes, I thought it was a useful post. It is a known fact that previous generation AMD cards perform worse with low end cpus than comparable nVidia cards. Seems like useful information that the new generation performs similarly. I dont see any "bashing", just a presentation of documented data.

I disagree!, nothing wrong with the thread contents, only some posters' expectations.

 

[IEC]

Well, if you want to focus on a single metric might as well focus on VRAM, speculation about future driver support, and lack of DX12 performance as well.

But I suppose that would be antithetical to the obvious editorial bias of the OP.

Personal attacks will not be tolerated.

[Jaydip]

So people are asking to lock threads when it doesn't fit your agenda? I wonder how many of these new guys are actually getting free stuffs from AMD, maybe durvelle(or w/e his forum name was) created quite a few accounts or maybe even evo.

 

[vissarix]

How could you defend a just released 14nm gpu which is slower and more power hungry then an 2 yrs old gtx970 on 28nm??

The hype train derailed guys, its over...no need to get angry...there is no gtx980 performance at 100w as some of you speculated

 

[Rvenger]

All I see is people whining about a benchmark not going in their favor? I am not locking this due to this being info you don't "agree with". Ignore it and move to a different thread if you don't feel it is appropriate.

Please stay on topic. Topic is CPU scaling. 480 appears to do fine in old ones and will do much better in DX12 / Vulkan games which are all future AAA ones.
