Under the hood, the Xbox 360 is a formidable piece of hardware. In addition to an IBM PowerPC-based CPU running at 3.2GHz and half a gigabyte of RAM, the 360 sports a customized ATI graphics processor capable of advanced antialiasing and shader effects. What that technical jargon means, in practice, is that new Xbox will have the processing power to deliver true 720p and 1080i wide-screen HDTV images for all of its games (by contrast, most games for the original Xbox maxed out at a DVD-level 480p)..
