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 PCMark Vantage performance at stock speeds was not inspiring, but it did catch up when we pushed the system.
For synthetic gaming tests we used the industry standard and overlockers bragging tool 3DMark 11. 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 V11 uses the DX11 API in addition to having support for CPU based Physics. Gone are the days of the PhysX inclusion giving you inflated scores.
Although the numbers here are very close (much like real gaming), we can see a few places where each board distinguishes itself. The X58-USB3 pulls it off in the CPU based Physics scores, at least when overclocked.
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 CB-R11 scores are fairly close across the X58 line up. We do find the X58-USB3 towards the bottom of the pack at stock speeds, but really not by much.
