Xbox 360 – Official specifications

0

Small preview imageAt numerous occations unofficial specifications have appeared for Microsoft’s console Xbox 360 but now that the console has finally arrived we can publish the real specifications that are in no way to be ashamed of. The most is correct compared to earlier speculations. IBM supplies the processor(s) and ATI the grpahics. Speakign the graphic circuit it’s a specially designed version of ATI’s R520-circuit that will be available to PCs soon. Compared to today’s grpahic circuits Xbox 360 is superior with 48 combined pixel and vertex piplines (ATI X850 XT has 16 pixel pipelines and 6 vertex pipelines). Even if the circuits doesn’t use the pipelines the same way the circuit in Xbox 360 is without a doubt faster than anything available today. Especially when it comes to applying antialiasing that seems to be a crucial component of the games to Xbox 360.
