Benchmarks: Winbench 99, SiSoft Sandra 2004

Winbench 99 V1.2 Source: e-Testinglabs.com

WinBench 99 is a subsystem-level benchmark that measures the performance of a PC's graphics, disk, and video subsystems in a Windows environment. WinBench 99's tests can run on Windows 95, Windows 98, Windows NT, Windows 2000, and Windows Me systems.

1b. Business Disk - 227/377


2a. High-End Disk - 200/400 35500


High-End Disk - 227/377 36900
3a. Business Graphics - 200/400 1280

4a. High-End Graphics - 200/400 2160
4b. High-End Graphics - 227/377 2170

HDD performance on the Gigabyte K8NNXP is extremely high, and much higher than that of the K8T800 motherboards. I'm at a loss to explain why, but we did run Winbench 99 a few times and always got the same results. We were also surprised to see that the Graphics portion of Winbench 99 doesn't get any tangible performance gain due to overclocking.

Sandra is designed to test the theoretical power of a complete system and individual components. The numbers taken though are again, purely theoretical and may not represent real world performance. Higher numbers represent better performance.

The processor scores what we'd expect from it at those given speeds. It's not surprising to see that the memory bandwidth when overclocked is less than at stock speeds.
