Overall System performance and Gaming
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 ASRock P55 Deluxe with a Core i7 870 is quite impressive. It even comes close to the X58 running a Core i7 965 and it stomps on the Core i7 920, as does the Core i5 750.
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. Due to the PhysX support and our use of an nVidia GPU we run with PhysX enabled and disabled to give you the best indication of real system performance. For testing we use the Performance test run.
The ASRock P55 Deluxe holds its own here and gives us a good idea of what we can expect from the PCI-e controller in the Lynnfield CPU.
Cinebench R10 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 R10 tests your systems ability to render across a single and multiple CPU cores. It also tests your systems ability to process OpenGL information.
In Cinebench we see the issue with the memory controller come out a little. We also see the benefit of Hyper Threading here as the i7 870 easily beats out the Core i5 even when running 200MHz slower and the i7 975 is only slightly behind the 1GHz faster Core i5 750 when clocked to 4.2GHz.
