ATI today announced the release of the X1900 range of videocards, which features a whopping 48 pixel shaders (vs 16 for the X1800) and other improvements including a larger on-chip buffer for better high-res performance. It certainly isn't cheap, at $649 for the high end Radeon X1900 XTX, and $549 for the Radeon X1900 XT. Reviews of the XTX and XT can be found at Tech Report, HardOCP, Guru3D, Beyond3D, PC Perspective, Hexus and Digit-Life. From HardOCP's article

It is quite clear that the X1800 XT is slower than the GeForce 7800 GTX 512 and the 7800 GTX 512 provides a better gaming experience. With the new Radeon X1900 XT and XTX, the performance these cards provide is now equal to that of the 7800 GTX 512 in most games. F.E.A.R. really is the only game in which the X1900 XT and XTX dominated the 7800 GTX 512. The X1900 XT is really what the X1800 XT should have been; it has just now come up to par with the 7800 GTX 512. If the rumors are true about the specifications for NVIDIA's GeForce 7 series refresh product -- we may see the X1900 XT and XTX getting trounced in the latest games by NVIDIA's next release. Competition is good, that is for sure, and it benefits the consumer greatly.
