GameSpy's "We Got Next", Part One

The first installment of GameSpy's "We Got Next" feature is online, providing quite a few details on the hardware we'll be seeing in Microsoft's next Xbox console. Check out these video specs:
Xenon's GPU is a generation beyond the ATI X800. Its clock speed is 500 MHz and it supports Shader 3.0. Developers are currently working with an alpha 2 GPU. Beta GPU units are expected by May and the final GPU is slated for a summer release. The final GPU will be more powerful than anything on the market today; in game terms, it would handle a game like Half-Life 2 with ease.
