A Tale of Two GTs: Radeon X1900GT by Sapphire and Powercolor

Test Setup

We included GT products from Nvidia to give a comparison of results. We also streamlined the tests we used just so people had a decent gauge without all of the extra pages to hunt through. One thing we will point out immediately is that the two cards have the same core, memory and clock speeds. They probably even came off the same production line. This means that the performance between the two should be identical.

Benchmark Results

3DMark05

In 3DMark 2005 we see two things that immerge from the results. The first is that the Radeon X1900 GT cards are ahead in most of the resolutions, but not by much. At 1600x1200 the factory overclocked XFX GeForce 7900 GT pulls ahead but then gives it back up to the ATI Radeon X1900 GT cards. When the image quality is turned up, the XFX GeForce 7900 GT does the inverse of the previous. It takes the lead all the way through the tests except for resolutions of 1600x1200. This is where the power of extra pipelines comes into play. Interestingly, the XFX card has twice as many pipelines yet only pulls ahead by 4% at 1024x768 and less than 2% at 1280x1024. It is at 2048x1536 and 2560x1600 that the excess full processing pipelines shows 27% and 22% increases.
