godhandiscen said:Yes, but now consider that the Xenos is a GPU with performance in between the HD2900 and the HD3500, and it is actually a feat of optimization.
I always thought Xenos had 8800 gt level of perfomance. You've to remember that there's no PC OS layers there. don't know if it really matters though.
Also they've multithreaded the engine and offloaded physics to CPU. 360 has quite a capable CPU.
