AMD Polaris architecture – GCN 4.0

Looks like increasing clockspeed by 150MHz increases the 3dmark 11 score by 200 points. A 1266MHz RX480 gets 18060 score so overclocking to 1400MHz should get it past 20000. Nice.:p

And 20,000 ish is pretty much stock 980ti - titan x territory i believe.

Weird that my OC 290X actually gets a higher score than your Fury Pro.

If the 480 is Fury level at stock speed then surely overclocking should get it to FuryX level. :eek:

The AoTS results make the 480 appear to be slower but the 3dmark 11 score indicates its around Fury Pro level. Maybe the DX11 improvements have indeed made a difference.

You are running an i7 4790K and he is running i5 3570K. Does CPU make a big difference in this benchmark?

OK I will.

I've looked at the fps in the detailed results section for all the cards. The 390 fps is almost the same as the 480 but the 480 beats the overclocked 290x in gpu test 4. The Fury also has by far the fastest gpu test1 but the slowest test4. Why can't anything be simple!

Btw how did you get such a high gpu score? Is it a 390x?

Nope, its an MSI R9 390 at stock (1040/1500). The relatively high score from my card compared to the likes of the Furys is leading me to believe this old test is becoming CPU bound.

SMT does help the scores a bit.

Is it possible if fs123 could reduce the clockspeeds on his Core i7 4790K to match the Core i7 4770 AMD used??

It says 4.7GHZ in his 3DMark11 run.

The Core i7 4770 runs at between 3.4GHZ to 3.9GHZ:

Ok I disabled turbo with Realtemp so the cpu only runs at 4GHz.

The results :

i7 4790K@4GHz
290X OC to 1171MHz/1450MHz : gfx score = 18205.........physics score = 10264

290X stock (1030MHz/1250MHz) : gfx score = 16343.........physics score = 11568

(i7 4770 @ 3.8GHz)
RX480 stock (1266MHz/2000MHz) : gfx score = 18060......physics score = 9109

Looks like the cpu clockspeed didnt make any difference above 4GHz.

Well it can't be that cpu bound because I actually got a higher score at 4ghz on the cpu.

Wow, that's odd! You can't make this sort of stuff up! Your CPU score dropped and pretty much matches mine though.

I guess we'll have to find a "leak" of a more modern benchmark to clear this up, this only gives us a very rough idea of how the new card performs. Would be nice if it is near Fury performance though.

Nice work, though I'm not sure what to conclude anymore! Definitely GPU bound the whole time there. Perhaps the RX 480 does match a highly clocked 290X or Fury then.

Well if the 3dmark 11 score of 18060 is legit then the 480 is on par with a Fury Pro/nano. My stock 290x only gets 16300 so it's definitely faster than that.

We need another Fury score with an i7 processor to get a better idea but the 480 is definitely looking good in DX11 at least.:D

Maybe I had something running in the background. Either way the 480 doesn't look too far behind and It beat the 290x at stock by quite a long way.

Looking at all of the test results 3d mark 11 doesn't seem cpu dependant. A 150mhz oc on the 290x increased the gpu score by over 10%..So im not surprised his score is equal to a stock Fury.

The 1171MHz overclock on my 290X was only for benching since it gets pretty toasty at that speed. I normally only run at 1100MHz. The 480 looks like a bargain and should run a lot cooler. I hope AMD announce the 480X soon.

I get a graphics score of 18360 with a msi 390 at 1080 core clock.

That would put the rx480 at under £200, £70 cheaper with more or less the same performance.

Not bad.
