* ATI: Xbox360 "Easily" as fast as PS3

Xbox/Xbox Games
The war of words goes strong - Xbox365 has word on ATI defending their graphics chip, saying it's "easily" as fast as the one in the PS3.

Numbers - the public loves them. Bigger equals better. It's one of the reasons Xbox 360 is called Xbox 360 rather than Xbox 2. Stack an Xbox 2 next to a PS3 on a shop shelf, and which is you average punter going to think is better? And this is similarly the case with Xbox 360 and PS3 graphical core speeds, reckons ATi - but we shouldn't allow ourselves to be blinded by what's written down on paper.
Xbox 360's Xenos graphical core runs at 500Mhz. PS3's nVidia-developed RSX graphical core runs at 550Mhz. However, ATi's Richard Huddy, whose job is talking to developers about the company's technology, says that the Xbox 360's unique graphical architecture quite capably makes up for the apparent shortfall between the two core speeds

"That mere 10% clock speed that RSX has on Xenos is easily countered by the unified shader architecture that we've implemented," is the word from Huddy in an interview with website Bit-tech.net.

Dipping further into technical details, Huddy says that "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."
Of course, the specs are pointless unless you've got a disparity like the PS2 and Xbox - and Sony looks to be closing that gap, though they're making some basic mistakes like not including a hard drive as standard equipment. It's really going to come down to the games.
