Pure computation is above and beyond in efficiency compared to what a driver can provide, imho.
The way I postulate it(sorry, I'm limited to the bounds of my imagination) the console's computational baseline will be above pc hardware's threshold at all times, overcoming the bottlenecks outright.
Sure a 7850 might have decent compute performance but even so depending on what type of calculations are been made the GTX 670 usually falls somewhere in between the 7850-7950 (meaning equal or better).
You also need to remember that compute performance does not equal better graphics. In terms of rendering power (shaders, raster operations ect.) the GTX 670 is far superior to a 7850. Its a better graphics
Sometimes GPU performance is measured in shader arithmetic flops (floating point operations).
The 7850 does 1.76 TFLOPS while the GTX 670 does 2,46 TFLOPS
But this is a pretty useless number on its own as there are many other factors that impact final real world performance. Things like memory bandwidth, ROP (Raster operations) ect.
Also the consoles have quite weak CPU's when compared to modern quad cores so depending on what type of game is being made some of the 7850 potential rendering power has to be used for compute stuff (AI, physics ect.) and this will further hamper the consoles graphical prowess.Edited by Bit_reaper - 7/4/13 at 12:55pm
