For a little over a year, ATI's Radeon X800 series GPUs have powered the company's high-end AGP offerings. Over that time, however, ATI has introduced a number of new graphics products, including the Radeon X850 XT PE that boasts dynamic clock gating and higher clock speeds than previous Platinum Editions, and the Radeon X800 XL built with 0.11-micron fabrication technology. For months, these new graphics cards were limited to PCI Express, but AGP versions of each have recently become available. ATI has also bolstered its AGP lineup with the addition of an All-in-Wonder Radeon X800 XT. Together, these cards breathe new life into a graphics interface that's been largely ignored for the last six months, but are they any good? Let's have a look.
