Back in March, we explored ATI and NVIDIA's strategies for tackling the new PCI Express graphics standard. At the time, ATI touted the benefits of a native approach to PCI Express that eschewed bridge chips like NVIDIA's High-Speed Interconnect (HSI). ATI's native PCI-E implementation was certainly an elegant solution, but at the time the company didn't have much to say about specific PCI Express graphics products. Now, more than two months later, ATI is unveiling a family of PCI-E offerings that includes Radeon X800, X600, and X300 series graphics products. Those familiar with next-generation graphics will no doubt recognize the Radeon X800, but the X600 and X300 are new, sort of. Join me as I uncover what's new, what's not, and what's missing from ATI's PCI Express graphics lineup.
