PCMark05 Pro Performance
PCMark05 Professional is part of the PCMark system benchmarking series from FutureMark, and was revamped to highlight current hardware and features additional multithreaded and multi-tasking performance tests. There is the usual selection of individual System, CPU, Memory, Graphics, and Hard Drive benchmark suites, and these continue to bridge the gap between synthetic and application-based benchmarks. For our purposes, the System, CPU and Memory areas will be where we concentrate our benchmarking efforts.
The PCMark05 System benchmark suite includes a wide range of tests, from Windows XP hard drive startup to video and audio encoding, and features a selection of standard desktop routines like text edit, virus scanning, and image decompression. Three of the benchmark scenarios are multithreaded, with the first two including two simultaneous tests, and the final one utilizing four program tests running simultaneously. For this test, the latest 1.2 patch + hotfix have been applied.
The PCMark05 System benchmark shows the 3.2 GHz Core i7-965 XE sitting in first place, but still not that far ahead of the Core 2 Extreme QX9770. The basic clock speed pattern holds after that, and the drop in QuickPath speed looks to have a significant impact on the Core i7-940.
The PCMark05 CPU benchmark suite follows almost the same pattern, and although the Core i7-965 Extreme Edition does post the highest score, we are not seeing these latest Intel processors running away with the contest yet.
The PCMark05 Memory benchmark testing gets us back on track, and we start to see the impact of the Core i7's integrated memory controller and triple-channel DDR3 memory architecture. It is the class of this memory test, moving well ahead of even the Core 2 Extreme QX9770 on a 1600 MHz FSB and using DDR3-1600.
