The Radeon X1900 XT in its turn only differed from its elder brother in having somewhat lower frequencies: 625/725 (1450) MHz as opposed to 650/750 (1500) MHz. Such a small difference couldn’t have a big effect on the performance in games as our tests proved (for details see our article called The Fast and Furious: ATI Radeon X1900 XTX Review). In most cases there was a negligible difference between a Radeon X1900 XTX and a Radeon X1900 XT or even none at all, although the latter came at an officially recommended price of $549, i.e. $100 cheaper than the flagship model!
