PC graphic technology has come a pretty long way since 2004 when the Xenos GPU for Xbox 360 (released in 2005) was completed by ATI.
GPU floating point performances
Xbox 360's Xenos GPU:
240 GFLOPS
mainstream PC graphics of 2008
1000 GFLOPS (1 TFLOP) via 4850 (one RV770)
top-end PC graphics of 2008:
4800 GFLOPS (4.8 TFLOPS) via Crossfire 4870X2 (four RV770s)
So in 2008 you could get anywhere from 4 to 20 times the graphics performance of
Xbox 360 in PC. This is only regarding GPUs, not the CPU side of things.
With the upcoming DX11 generation of AMD GPUs, performance should roughly double across the board, from mainstream to highest-end. So we're looking at 8 to 40 times Xbox 360 graphics performance.
Nevermind what may or may not happen with the refreshed Xbox 360 next year, there's not enough to guess on, performance wise. Maybe it'll only be a RAM increase and no upgrade to the GPU.
Regardless, I hope that the true next-gen Xbox3 in 2012 or so, has the kind of performance you'd get from four RV870 DX11 class GPUs, in a $299 ~ $399 box that developers can target their games toward. That would be a huge leap from Xbox 360, bigger than the leap from the original Xbox to Xbox 360.
