Unified architecture gives Xbox 360 the graphical edge, so says ATI. PS3 may be faster on paper, but the Xbox's standards are easy to meet for grand scale games.

An ATI developer went into detail about the Xenos chipset used in the 360 and how well it went up against NVIDIA's RSX for the PS3.

Although the RSX is more powerful in terms of raw specifications - it runs at a higher clock speed for a start, 550Mhz rather than the 500Mhz speed of the Xenos part the unified shader architecture used by ATI will give Xbox 360 the graphical edge, which Nvidia has downplayed the importance of and has publicly stated that it doesn't believe that this is the best path to improved graphics performance.

"That mere 10 per cent clock speed that RSX has on Xenos is easily countered by the unified shader architecture that we've implemented," he claimed. "Rather than separate pixel and vertex pipelines, we've created a single unified pipeline that can do both."
