According to the GPU hierarchy chart, it's around a HD 4670 - which will run just about every game on medium settings at 1280x720.The real miracle is how they manage to make it look so good with so little of a frame buffer - 512MB ram is shared between the CPU and GPU.[/citation]
Ya, but the RSX is a crippled 7800GTX 512 but then with only a 256mb buffer. On the hierarchy charts, the 7800GTX is actually just one tier below the 4650 DDR3, which is a bit slower than than the 4670 (I think it's 625 core vs 750?) I'm guessing that the RSX is about as powerful as a 4650 DDR2 and the Xenos gpu is about as powerful as the 4670 or 4650 DDR2. One thing that I am curios about though is this: How did ATI squeeze SO MUCH performance out of Xenos' 48 shaders?
