Asus LGA1156 P7P55D-E Pro Motherboard Review
Test Systems, SiSoft Sandra
How we configured our test systems: When configuring our test systems for this article, we first entered their respective system BIOSes and activated AHCI. Memory timings, voltages, and CPU speeds were set to Auto; the RAM was run at 1333MHz, with default timings enabled. Windows 7 64-bit was installed and fully patched on both systems.

We began testing with SiSoftware's SANDRA, which stands for System ANalyzer, Diagnostic and Reporting Assistant. We examine a CPU's multimedia and arithmetic performance using Sandra, as well as the motherboard's peak memory bandwidth. The difference between the two platforms should be minor given their identical configurations.
The integer performance delta between the Asus and Gigabyte boards is surprising, particularly considering their FPU scores are neck-and-neck. The culprit here is almost certainly Turbo Boost; Intel's clockspeed boosting technology only engages under certain conditions and thermals. The multimedia and memory bandwidth benchmarks were ties as we expected.
