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.

On System batch Core 2 Duo E6700 was faster than competing CPUs from AMD: 7.37% faster than Athlon 64 FX-62, 11.52% faster than Athlon 64 FX-60, 13.45% faster than Athlon 64 X2 5000+, 17.06% faster than Athlon 64 X2 4600+ and 54.25% faster than Athlon 64 3800+. It was also 55.01% faster than Pentium 4 550.

On this same batch Core 2 Extreme X6800 was 5.57% faster than Core 2 Duo E6700 and 13.35% faster than Athlon 64 FX-62, 17.73% faster than Athlon 64 FX-60, 19.77% faster than Athlon 64 X2 5000+, 23.58% faster than Athlon 64 X2 4600+, 62.84% faster than Athlon 64 3800+ and 63.65% faster than Pentium 4 550.

On CPU batch Core 2 Duo E6700 was once again faster than competing CPUs from AMD: 17.27% faster than Athlon 64 FX-62, 26.58% faster than Athlon 64 X2 5000+, 27.18% faster than Athlon 64 FX-60, 37.90% faster than Athlon 64 X2 4600+ and 64.04% faster than Athlon 64 3800+. It was also 93.89% faster than Pentium 4 550.

On this same batch Core 2 Extreme X6800 was 9.71% faster than Core 2 Duo E6700, 28.65% faster than Athlon 64 FX-62, 38.87% faster than Athlon 64 X2 5000+, 39.53% faster than Athlon 64 FX-60, 51.29% faster than Athlon 64 X2 4600+, 79.97% faster than Pentium 4 550 and 112.71% faster than Athlon 64 3800+.
