Specification
We put the specifications of the Radeon X1900 GT, Radeon X1800 XT and GeForce 7900 GT into one table for better comparison:

As you see, it’s hard to exactly pinpoint the Radeon X1900 GT’s position relative to other products. On one hand, the 36 pixel processors and the considerably higher GPU frequency should give the new card an edge over the GeForce 7600 GT in newest games. On the other hand, the Radeon X1900 GT has two times less of TMUs, which may affect its performance negatively in applications requiring high texturing performance. The use of only 12 TMUs is somewhat justifiable because the X1900 GT has a lower memory bandwidth than the GeForce 7900 GT, even though its efficient rig-bus memory controller may make up for this difference to some extent.
The new card also has obvious advantages over its market opponent in the image quality improvement area. We mean its support of FSAA and HDR simultaneously and its use of a higher-quality anisotropic filtering algorithm.
The Radeon X1900 GT can work in a CrossFire tandem, and you don’t need a Master card with a Compositing Engine for that. All you have to do is to install two Radeon X1900 GT cards into your CrossFire-compatible system (based on a CrossFire Xpress 3200 or Intel 975X chipset, for example). Then you just enable the appropriate option in Catalyst’s Control Center. The two cards will communicate via the PCI Express bus.
We will be examining PowerColor’s version of Radeon X1900 GT in this review. Let’s have a closer look at this card now.
