Here is where we dig out the FutureMark tests.
For overall system performance we use PCMark Vantage. This is run in both x86 and x64 mode to give the best indication of performance.
The X58-UD9 comes out on top here for both the stock and overclocked runs. In fact, even under the x86 suite the UD9 comes out over 1,000 points ahead.
For synthetic gaming tests we used the industry standard and overlockers bragging tool 3DMark Vantage. This is a test that strives to mimic the impact modern games have on a system. Futuremark went a long way to change from the early days of graphics driven tests to a broader approach including physics, AI and more advanced graphics simulations.
3DMark Vantage uses the DX10 API in addition to having support for PhysX. As we are no longer using an NVIDIA GPU for testing (at least until we can get a GTX 4xx card) you will only see the CPU based PhysX results in the scores. For testing we use the Performance test run.
At stock speeds the X58A-UD9 gives us a great score. It is over 3,000 points higher than the P6X58D-E. However, for some reason when we overclocked the system the numbers did not scale in the same way. We see the lower clocked P6X58D-E scrape by the UD9.
Cinebench R11. x64
Cinebench is a synthetic rendering tool developed by Maxon. Maxon is the same company that developed Cinema4D, another industry leading 3D Animation application. Cinebench R11.5 tests your systems ability to render across a single and multiple CPU cores. It also tests your systems ability to process OpenGL information.
The Cinebench scores are close; they are close enough that although we can call a "winner", the overall performance difference between the two is probably negligible. That is unless the rendered scene is lengthy; then even minor differences in single frame renders can have a huge impact.
