The cut-down (18 or 20 EUs active) 7870 in the PS4's semicustom 'APU' is roughly comparable to a 750ti. Total system power for the PS4 is a hair under 140W, so a TDP of just under 100W for the 'APU' is probably about right.The rub is that the PS4 (and XB1) dies are massive volume parts, and are not suitable for use as a general x86 CPU (too many custom bits). A 'generic' APU variant would be a big die, with a much smaller market, so would not come cheap.
