We measured processing performance using PCMark05 Professional program. PCMark05 Professional measures the system performance by running several tests. The System batch, which was the one we used, performs the following tests: HDD XP Startup, Physics and 3D, 2D Transparent Window, 3D Pixel Shader, Web Page Rendering, File Decryption, 2D Graphics Memory – 64 lines, HDD General Usage and three multithreading tests. The results are given in a PCMark05 specific unit.
All motherboards based on Intel P965 chipset achieved a similar performance on PCMark05 System batch. ASUS P5B was 3.84% faster than Intel D975XBX2 and 4.13% faster than Intel D975XBX when our memories were configured to run at 800 MHz, and 4.87% faster than Intel D975XBX2 and 5.16% faster than Intel D975XBX when our memories were configured to run at 1,066 MHz (on Intel motherboards the memories were always running at 800 MHz; it is also important to note that Intel 975X chipset does not officially support DDR2-800).
