Science Mark 2.0 is an attempt to put the truth behind benchmarking. In an attempt to model real world demands and performance, ScienceMark 2.0 is a suite of high-performance benchmarks that realistically stress system performance without architectural bias. All of our testing was completed on the 32 Bit Final benchmark version that is dated March 21st 2005.
PCMark05 is an application-based benchmark and a premium tool for measuring overall PC performance. It uses portions of real applications instead of including very large applications or using specifically created code. This allows PCMark05 to be a smaller installation as well as to report very accurate results.
As you can see, both these sets do very well, keeping up with one another in every benchmark and speed. The PC-3500 does outpace the PC-4000 ever so slightly in most of these tests, due to the tighter timings you are able to run with them. Once you start reacher higher speeds, we see that the gap tightens, and the PC-4000 actully takes the lead in a few of these tests.
