We began our testing with SiSoftware's SANDRA 2009 SP1, the System ANalyzer, Diagnostic and Reporting Assistant. We ran three of the built-in subsystem tests that partially comprise the SANDRA 2010 SP1 suite with the Gigabyte X58A-UD3R and the EVGA X58 SLI Classified. All of the scores reported below were taken with the processor running at its default clock speeds of 2.66GHz but with Intel Turbo Boost enabled for a final clock speed of 2.8GHz and 3GB of DDR3-1066 RAM running in triple-channel mode.
Equal processors, equal platforms, equal performance. The Gigabyte board posts a tiny lead in several benchmarks, but nothing that escapes a standard margin of error.
