FutureMark PCMark04, 3DMark2001 SE and 3DMark05
First of all we decided to discuss the results obtained in popular synthetic tests from FutureMark:
PCMark04 test uses Hyper-Threading technology a lot, which allows Intel processors to show better results in this test package. As far as the performance differences between processor families from Intel are concerned, we can say that 6XX family with larger 2MB L2 cache memory are just a little bit faster than Pentium 4 5XX. While Pentium 4 Extreme Edition 3.73GHz outperforms its predecessor, Pentium 4 Extreme Edition 3.46GHz on Gallatin core, due to significant working frequency increase and a newer processor die.
The results obtained in the subtest measuring the memory subsystem performance are also very interesting. Larger L2 cache in Pentium 4 6XX processors sped up their work with the data, which allowed these CPUs to catch up with Athlon 64 processors, which have always been strong in this test due to the integrated memory controller. In other words, the use of large 2MB L2 cache eliminated high latencies of the DDR2 SDRAM used in contemporary Pentium 4 systems.
