SuperPi, PCMark05, 3DMark06

The highest result in the computational SuperPi test belongs to DDR2-1200 SDRAM. However, DDR3-1600 SDRAM with 7-6-6-18 timings runs neck and neck with it. Therefore, we can actually hope that another slight frequency increase or timings lowering may push DDR3 to the leading positions fairly soon.

Almost the same is true for PCMark05 results. By the way, note that despite its relatively low frequency, especially according to today’s standards, DDR2-1000 lets the systems runs at pretty decent speeds. This is another piece of evidence that we should retire DDR2 SDRAM just yet.

Performance in 3DMark06 hardly depends on the memory subsystem parameters. Nevertheless, all the tendencies described above find their way here, too.
