7850 vs 5870

post #1 of 9
Thread Starter 
What type of performance increase would i get from going from a 5870 at 900/1300 to a 7850 at 1200~ core?

Its around 10-25% better depending on the benchmark:

I'd say a 7850 with 1200 core should be a good 30-40% faster @ 1080p than a 5870@900 core.

HD 7850 at 1.2 Ghz matches a GTX 580. HD 5870 performance in the latest DX11 games will be far lesser than HD 7850 (1.2 Ghz) . the tesselation and compute performance of HD 7850 is much better compared to HD 5870.

BF3 1920 X 1200 4X AA

HD 5870 - 35.1
HD 7850 (1 Ghz) - 45.4
HD 7850 (1.245 Ghz) - 50.2
GTX 580 - 51.7

Crysis 2 1920 x 1200 DX 11 Ultra 4 AA high res textures

HD 5870 -32 fps
HD 7850 (1 Ghz) - 45 fps
HD 7850 (1.12 Gh) - 49 fps
GTX 580 - 49 fps

In the latest DX11 games the performance improvement is 40 - 50% at the highest settings.
