Intel SkullTrail Preview – Dual Core 2 Extreme QX9775 Processors

Sandra XII SP1 Memory Bandwidth

Sisoft; Sandra XII SP1:

The Sisoft Sandra XII SP1 benchmark utility just came out a couple months ago and we have started to include it in out benchmarking. With Sandra XII SP1 you can now easily compare the performance of the tested device with its speed and its (published) power (TDP)! Sandra XII SP1 also has SSE4 (Intel) and SSE4A (AMD) benchmark code-paths, which is great for those of you testing next-generation AMD & Intel chips.

Results: Sandra XII SP1 showed that the Skulltrail system doesn’t break any records in the memory bandwidth test. With 4GB of 800MHz CL5 FB-DIMM Micron memory modules it just didn’t have the muscle to compete with DDR3 memory modules. The Intel QX9770 does have improved memory bandwidth over the QX6850, but that is because the QX9770 is running at DDR3 1600MHz CL7 while the QX6850 is running DDR3 1333MHz.
