Today we'll be comparing the Xtasy 9800 Pro 256MB's performance with a Radeon 9800 Pro 128MB card from ATI and against the DustBuster, NVIDIA's GeForce FX 5800 Ultra. Despite the fact that we're using NVIDIA's latest (and supposedly cheat-free) 45.23 Detonators, we elected to create our own custom demos for a number of our game benchmarks. In the interest of transparency, we're also making our demos available for download.

In an attempt to stress the Xtasy 9800 Pro's 256MB of memory, I've run through our graphics suite with high-detail image quality settings, and also with a couple of levels of antialiasing and anisotropic filtering. All cards were tested with 4X antialiasing and 8X anisotropic filtering, and the Radeon cards were also tested with antialiasing and anisotropic filtering maxed out to 6X and 16X, respectively.

We used the following versions of our test applications:

The test systems' Windows desktop was set at 1024x768 in 32-bit color at a 75Hz screen refresh rate. Vertical refresh sync (vsync) was disabled for all tests.

All the tests and methods we employed are publicly available and reproducible. If you have questions about our methods, hit our forums to talk with us about them.
