ATI’s Effort Better than the RSX? | PS3Blog.net
As the launch of the next generation of consoles approaches, much is being said about which system is better. While the PS3 architecture isn’t quite locked down yet, it is known that it has a 550MHz RSX graphics chip by nVidia. The Xbox 360 has 500MHz part by ATI. Not much of a difference, but what difference there is is more than made up by the ATI’s architecture:
Richard is adamant that the extra graphics speed on paper is more than made up for by the differing architecture of the Xenos. “That mere 10% clock speed that RSX has on Xenos is easily countered by the unified shader architecture that we’ve implemented.
“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% efficiency all the time, rather than having some pipeline instructions waiting for others. 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.”
