Ok to the question wether its 7850 or 7970m in the PS4, its neither. 7850 is 16 CUs 7970m is 20 CUs PS4 is 18 CUs. Its also going to have an improved architecture (8 ACEs) Its more like the 7790 with more CUs/ROPs/TMUs. |
PS4:
18 Compute Units (1152 Stream Processors)
800Mhz
32 ROPs
72 TMU (speculated or is it confirmed now?)
1.84 TFLOPS Single Precision compute power
7850 is 16 CUs but with bigger clock (860Mhz in reference models) it compensates it mostly.
So the easiest to compare it would be 7850, not reference ones with bigger clocks (900+) are faster.
Going down to 7790 makes problems with everything needing to be better.... not a good point of reference.
And 7870 is too far in lead to catch it. However IF Sony raised clocks behind everybody backs on their APU :) like they made that with that "4GB? It's 8GB now. " switch :)
7870
20 Compute Units (1280 Stream Processors)
1000Mhz Engine Clock
32 ROP Units
80 Texture Units
2.56 TFLOPS Single Precision compute power
