sorry, should have been clearer with what i said.

For Siege of Shanghai, compare the DirectX benchmarks at 3840x2160 vs. 1280x720.
FPS at 1280x720 is around 65fps
At the much much higher resolution of 3840x2160, FPS reduced by just 25% to around 48fps.

3840x2160 is 9 times as many pixels as at 1280x720, yet the fps drop is so less.

You dont know cpu bottleneck on lower res? Look the difference on 720p d3d vs 720p mantle.

@sugarhell and
@SgtBilko below,
yep, i got it...thanks to both of u

yes, i was aware of the CPU being a factor at lower resolutions.
EDIT: just that i expected a more drastic fall in the fps

Low Res = CPU Bound

High Res = GPU Bound

Most simple way i can put it, I'm assuming they ran these tests with one card otherwise the performance at high res would be greater.

So after looking at all the posted benchmarks it looks like crossfire benefits more then a single GPU which is interesting.

what i see since i bought my 290X early december.

I HAD MANTLE FRAMERATES IN BF4 back then. over 100 fps

only to drop every patch and driverrelease.


NOW MANTE WILL GIVE THAT SAME FRAMERATE BACK.


who are you trying too fool AMD ????
