Let see how Kepler mid range offering does. Cap verde pro (ie 8 compute units) is the GPU offering the highest perf per watts now.Yeah, Kepler would be the better console GPU for sure it seems. Pretty odd how Sony jumped ship at exactly the wrong time. Prior to Kepler AMD was the markedly superior choice imo.
A major point of Kepler is less compute focus more gaming focus, which obviously suits consoles to a tee.
I dont think MS would go with Nvidia. You never know though, would be wild.
And Sony seems to go for APU so Nvidia is out of the picture.
