High-End Graphics Cards

  • ATI Radeon X1900 XT
  • ATI Radeon X1900 GT
  • ATI Radeon X1800 XT
  • Nvidia GeForce 7900 GT

The high-end graphics card class currently includes a multitude of diverse products that vary in their actual price from $250 to $350 and even to $400 depending on the manufacturer and accessories. And a more expensive product is not necessarily faster or better suited for the next generation of games than a cheaper one. Graphics cards of this category deliver similar performance, making your shopping choice harder.

The Radeon X1900 XT and the Radeon X1900 GT stand out among the more expensive products. These two are meant for top-end computer systems and come with a dual-slot cooler whereas the Radeon X1900 GT and the GeForce 7900 GT have smaller coolers. Unlike most of ATI’s Radeon X1900 and X1800 cards, GeForce 7900 GT cards don’t generally support the video capture feature, but this is not a big problem in the era of digital cameras. All the mentioned graphics card models support dual-link DVI.

Power Consumption

Power Consumption Details (Click to enlarge):

A very economical solution, the Nvidia GeForce 7900 GT requires much less power than ATI’s Radeons it rivals with. For example, the Radeon X1900 XT, which corresponds to the GeForce 7900 GTX in performance, consumes more than twice the amount of power the 7900 GT needs. Although the Radeon X1900 GT is an economical solution too, it looks voracious in comparison with the GeForce 7900 GT.

Noise Level

We’ve already said it in our reviews that Nvidia took a very ill-designed cooling system for its GeForce 7900 GT. As a result, it is the loudest product among top-end graphics cards because it cannot vary its fan speed depending on the GPU temperature and is always audible when your computer is turned on.

The Radeon X1900 XT and the Radeon X1800 XT come with identical cooling systems and produce the same amount of noise (45dBA), which is a little over the noise level of the Radeon X1900 GT. You should be aware that there exist versions of the Radeon X1900 GT, Radeon X1800 XL and Radeon X1800 GTO with different cooling systems and, accordingly, with different noise characteristics.
