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
1.84 TFLOPS Single Precision compute power

7850 is 16 CUs but with bigger clock (860Mhz in reference models) catches somewhat.

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....


 I think it can't be really compared, its really different from a 7850 in terms of architecture. 

Its like if 7870 and 7850 made a child the 7860. And the 7860 has some 7790 genes in it. The child is a 7860 but its clockspeed genes are kind of weak. So it becomes a 7855 unless Sony decides to increase the clockspeeds.
