Our computation benchmarks are meant less to be a comparative test, and more of a validation test that nothing strange is going on. We don't expect any non-trivial differences in these tests, and it's only when there are differences that we become alarmed.
We see nearly identical performance between all three boards in the computational benchmarks, which is as expected, and is a validation that each board does not have any gaping flaws or computational disruptions. We do see a larger overall performance boost during overclocking for the P9X79 boards, but, again, we see very slim differences which we could not call appreciable or statistically significant enough to draw a particular advantage toward any of the boards.
We do see a roughly 6.7% advantage in the P9X79 Deluxe over the X79-UD3, with an edge of 3.8% over the P9X79 in copy speeds. Read and write speeds are nearly identical for both the P9X79 boards, and carry a 3.3% advantage over the X79-UD3.
