SiSoft Sandra 2002 Benchmarks: CPU, Multimedia And Memory

There are no surprises with the results of the CPU arithmetic and multimedia benchmarks using Sandra 2003. A processor's FPU and integer units work more rapidly when the speed is raised.

The measurement of the memory bandwidth shows that the memory interface of the 845MP really gets down to business. The values lie at 2000 MByte/s and are thus very close to the theoretical maximum memory bandwidth of 2100 MByte/s (DDR2100 RAM).

What appears to be higher memory throughput on a slower CPU compared with one running at a higher speed is a measurement uncertainty produced by Sandra 2003. This phenomenon occurs frequently with Sandra, but is no reflection of reality.
