Our testing methods
All tests were run three times, and their results were averaged, using the following test system.
|Processor||Athlon 64 FX-53 2.4GHz|
|System bus||HT 16-bit/1GHz downstream|
|Motherboard||DFI LANParty NF4 Ultra-D|
|North bridge||NVIDIA nForce4 Ultra|
|Chipset drivers||ForceWare 6.53|
|Memory size||1GB (2 DIMMs)|
|Memory type||OCZ PC3200 EL Platinum Rev 2 DDR SDRAM at 400MHz|
|CAS latency (CL)||2|
|RAS to CAS delay (tRCD)||2|
|RAS precharge (tRP)||2|
|Cycle time (tRAS)||5|
|Hard drives||Seagate Barracuda 7200.7 NCQ 120GB SATA|
|Audio drivers||Realtek 371|
|Graphics 1||NVIDIA GeForce 6800 GT 256MB with ForceWare 71.89 drivers|
|Graphics 2||ATI Radeon X800 XL 256MB with CATALYST 5.4 drivers|
|Graphics 3||ATI Radeon X800 XL 512MB with CATALYST 5.4 drivers|
|OS||Microsoft Windows XP Professional|
|OS updates||Service Pack 2, DirectX 9.0c|
Today we'll be looking at the Radeon X800 XL 512MB's performance against that of the Radeon X800 XL 256MB and GeForce 6800 GT. Since all three cards have plenty of horsepower, we've only tested with antialiasing and anisotropic filtering enabled.
Thanks to OCZ for providing us with memory for our testing. If you're looking to tweak out your system to the max and maybe overclock it a little, OCZ's RAM is definitely worth considering.
We used the following versions of our test applications:
The test systems' Windows desktop was set at 1280x1024 in 32-bit color at an 85Hz screen refresh rate. Vertical refresh sync (vsync) was disabled for all tests. All of the 3D gaming tests used the highest possible detail image quality settings except where otherwise noted.
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.
