SiSoft Sandra 2005.SR3
We ran the standard SiSoft Sandra synthetic processor test.
ScienceMark 2.0 BLAS Test
This test from the ScienceMark 2.0 suite does matrix multiplies very quickly in order to find the top MFLOPS (millions of floating point operations per second). SGEMM runs them in single precision and DGEMM runs them in double precision.
The performance scores from all three motherboards here are nearly identical as we would expect using the same processor in each test bed.
