Benchmark Results: SiSoftware Sandra

System Builder Marathon, March 2011: $2000 Bonus Build
By

With the same model processor and even the same overclock applied, we expect Sandra’s Arithmetic and Multimedia benchmarks to reveal parity between the original and alternative $2000 builds.

The expected equality in CPU performance aside, the one place our new build stumbled was in memory overclocking. We simply couldn’t get the same parts to run at the same speed with the new motherboard. Rather than the original system’s DDR3-1866 CAS 8, the best the new build could accomplish was DDR3-1600 CAS 7.

Note that new system’s memory performance was worse than the original PC’s at stock speed, and that its CAS 7 performance was barely better than the base-speed CAS 8. Sandra has awarded big bandwidth gains for small latency improvements in past systems, but that didn’t happen with this hardware.
