Memory Tests
For the rest of the benchmarks, both 915P-A and PF4 were equipped with DDR-II memory at 533MHz, a Pentium 4 560 and an NVIDIA 6800 GT on PCI Express.Pifast
The 915P-A is the slight winner. With both boards from the same vendor, using the same chipset, memory at the same speed and latencies, similar BIOS revisions, the same graphics card and the same OS and driver configuration, it's no surprise that they're similar in performance.
ScienceMark 2.0 - Memory Bandwidth
The PF4 offers slightly more memory bandwidth in our ScienceMark 2.0 test, but both are very similar.
ScienceMark 2.0 - Memory Latency
It's the same case here, with both board's performance pretty much identical. Let's have a look at CPU performance.
