PCMark05 Professional measures the system performance by running several tests. We selected two batches for our comparisons, System and CPU.

The System batch 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 CPU batch performs the following tests: File Compression, File Decompression, File Encryption, File Decryption, Image Decompression, Audio Compression and two multithreading tests.

The results are given in a PCMark05 specific unit.

Some applications don’t take advantage of having more than two CPUs installed on the system, and PCMark05 system batch seems to be one of them. Here Core 2 Extreme QX6700 was 3.26% faster than Core 2 Duo E6700, but Core 2 Extreme X6800 was 3.02% faster than the reviewed CPU. These differences are low, though.

Compared to other CPUs, Core 2 Extreme QX6700 was 14.54% faster than Athlon 64 X2 5000+, 61.74% faster than Pentium 4 3.4 GHz and 65.26% faster than Pentium 4 3.2 GHz.

On PCMark05 CPU batch Core 2 Extreme QX6700 was the fastest CPU, as this batch seems to be using more than two CPUs for its tasks. Here the reviewed CPU was 13.18% faster than Core 2 Extreme X6800, 24.93% faster than Core 2 Duo E6700, 58.63% faster than Athlon 64 X2 5000+, 105.45% faster than Pentium 4 3.4 GHz and 114.30% faster than Pentium 4 3.2 GHz.
