On September 14, ATI will set loose its new flagship card. The Radeon X1950 XTX can purportedly outperform its nearest competitor, the GeForce 7950 GX2, in “extreme high definition” resolutions using only half the processors. It can be run individually, or paired with another x1950 XTX in Crossfire mode to deliver even more performance.
From what I gather, the X1950 XTX uses dual-GPUs and GDDR4 with a data rate of 2Ghz. Unfortunately the press release mainly uses lots of hortatory language, provides little firm technical data. It does, however, state that the Radeon X1950 XTX will retail for $449 and that it will be available soon in select Dell machines.
