ethomaz, you posted a benchmark of the desktop 7850 GPU. Doesn't this rumor base the GPU off of the M (mobile series) GPU? That would make a big difference in the benchmarks you posted. Very big difference.

What difference?

HD 7970M (Mobile): 1280SPs @ 850Mhz
HD 7850 (desktop): 1024SPs @ 860Mhz
Orbis (PS4K): 1152SPs @ 800Mhz

The PS4K GPU is more inline with the desktop version than the mobile one... the Mobile is stronger in graphcis power so because that the Eurogame said the Orbis GPU is 10% less powerful than a HD 7970M.

For comparison the HD 7850 is the best choice.

I suppose that is a decent comparison. However, that is assuming a 2GB of dedicated GDDR5 VRAM. That only leaves 2GB for the rest of the PS3 of which .5-1GB is reserved for the OS. Granted, GDDR5 is faster than DDR3, but you have to wonder if the lower quantity will affect anything or if developers will have issues porting between the differences of the Wii U, PS4, and NextBox.

Wii U - 2GB total RAM (DDR3? can't find it anywhere) - 1GB reserved for OS

PS4 - 4GB total RAM GDDR5 - 0.5GB/1GB reserved for OS

NextBox - 8GB total RAM DDR3 - 2GB/3GB reserved for OS

Wii U to PS4/NextBox will again be difficult and show a huge difference. PS4 to NextBox will be interesting working with half the RAM at higher speeds or if being able to store more in combincation with EDRAM will be better in the end.
