ATI Radeon X1900XTX - Performance and overclocking

We've taken a closer look at ATI's new flagship. Radeon X1900 XTX has spent some time in our test lab and except for our regular tests we did some overclocking with both air and water.

Here we go again. The video card market is bubbling and the manufacturers are playing a multinational chess game with pieces in the form of video cards, paper launches and media hypes. Half a year ago, it appeared that everything wasn’t right with ATI’s R520 video circuit. Because of an irritable transistor failure, ATI was trapped on the playing field and nVidia got a 4 month performance advantage. When the R520 finally hit the market in November, nVidia had saved its best circuits for what would become the 7800GTX512, and also the fastest video card on the market. But nVidia’s shrewd moves were over and now it was ATI’s turn. ATI had in parallel with the R520 also developed a circuit codenamed R580. With a more mature 90nm-manufacturing process and multiple enhancements to the core, it was now time for ATI to perform a castling and get back on the playing field.

On the 24th of January, ATI officially announced their X1900 video card series with the obvious goal to retake the performance throne. The cards included in this series are as of today: X1900XTX, X1900XT, X1900AIW (All-In-Wonder) and we have yet to see if ATI will launch a card corresponding to a X1900XL. In this review we will take a closer look at the fastest card, X1900XTX, see how it performs in some common games and in the end perform an overclocking-evaluation.

We will begin by looking at its specifications.
