Using the built-in WinRAR benchmark we can measure how the Core i5 750 processor is performing on each of the three P55 motherboards tested. As you can see, the weaker memory bandwidth performance of the Asus P7P55D Deluxe motherboard do not appear to be hindering its performance in this test either.
While the Asus P7P55D Deluxe was slower than the Maximum III Gene in both SPECviewperf tests, it was able to match the performance of the MSI P55-GD65 motherboard.
Finally, the last synthetic application we used to benchmark our P7P55D Deluxe was CINEBENCH R10, which again placed the board roughly on par with the competition. The P7P55D Deluxe trailed the MSI P55-GD65 by a small margin in the multi-GPU rendering test, though it’s nothing to be concerned about.
