ATI claim Xbox 360 has edge over PS3
One of ATI's leading graphical chip designers Richard Huddy has claimed in a new interview that despite better specifications on paper, the PS3 will be beaten graphically by the Xbox 360 in the upcoming next-gen console war. ATI's Xenos hardware used in the new Xbox is 50mhz slower on paper than NVIDIA's RSX engine used in the Playstation 3, however Huddy claimed that the 'unified shader architecture' of his creation would ultimately give Microsoft's machine the edge.
"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 stated in the interview with a technology site. "Rather than separate pixel and vertex pipelines, we've created a single unified pipeline that can do both."
"Providing developers throw instructions at our architecture in the right way, Xenos can run at 100 per cent efficiency all the time, rather than having some pipeline instructions waiting for others," the expert explained. "For comparison, most high-end PC chips run at 50-60% typical efficiency. The super cool point is that 'in the right way' just means 'give us plenty of work to do'. The hardware manages itself."
NVIDIA would counter this lofty claim by stating they do not believe that unified shaders are the way to top-notch graphical performance, and the differing technological ideologies looks certain therefore to be tested. To this argument, Huddy countered: "This time around, they don't have the architecture and we do, so they have to knock it and say it isn't worthwhile," he argued. "But in the future, they'll market themselves out of this corner, claiming that they've cracked how to do it best. But RSX isn't unified, and this is why I think PS3 will almost certainly be slower and less powerful."
This statement is a bold one, given that most experts, including developers, are currently claiming that the PS3 is likely to be the more powerful, though until specifications are finalised and games tested, it seems the answer remains tantalisingly ambiguous. This despite Sony's extra six months and loftier claims on paper. More soon.
