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.

Here Core 2 E6750 achieved the same performance level of Core 2 Duo E6700. Notice that we are using a newer version of PCMark05, which is now capable of taking advantage of more than two CPU cores, as now QX6700 achieved the highest score and on our previous tests Core 2 Extreme X6800 had been the fastest CPU on this program.

On PCMark05 CPU batch the same thing happened: Core 2 Duo E6750 achieved the same performance level as Core 2 Duo E6700.
