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 Phenom II X4 940 shows a performance improvement for AMD in the PCMark05 System benchmark, and that the 3.0 GHz clock speed certainly pays off. The new Phenom II also compares quite well against the Core i7-920 and 940, coming within a hair of matching the latter.
The PCMark05 CPU benchmark also shows some very nice results for the Phenom II X4 processors. The 3.0 GHz Phenom II X4 940 finishes well ahead of the older Phenom X4 models, while outperforming the Core 2 Extreme QX6850.
Testing in the PCMark05 Memory benchmark didn't show the Phenom II X4 in the best light, and while it was impossible to think any new Phenom-based architecture could ever match the triple-channel DDR3 performance of the Core i7, AMD still falls behind the existing Core 2 Duo and Quad processors.
