I think its safe to assume we will get the latest features on the next gen consoles. DX11.1, tesselation, FXAA should be a no brainer. So in that regard, we will be on par with PCs. Also, the GPU in next gen consoles should have much much better GFLOPS per Watt performance than a GTX 480. We may see 80% of 480 performance power with a ~80 Watt TDP GPU. GTX 480 was a power hungry beast and had something like a 300 Watt TDP lol... I think the closest GPU available on the market today that is ready for consoles is the AMD 7770. Of course, next year will bring the new set of GPU's which will be even more efficient so we may see 7850 like performance under a 100 watt TDP. |
Sony probably won't get DX11.1 features, it's Win8 exclusive.
I'm not convinced perf/watt will be much better, because it will be 28nm at best compared to 40nm (so at best 50% savings, more like 30-40%). Even 80W power use would be unacceptable, because the PS3 at launch was hot/loud/bulky and only consumed 130W under load including CPU and storage. Also there will not be mid-cycle die shrinks or not as many because 22nm is basically end of the line for everyone except Intel.
The next set of GPUs will not be more efficient, since they are also on 28nm and the architecture for both is pretty close to optimal/general-purpose right now.
