Performance Comparison

As usual, we are going to compare the mainboards speeds in two different modes: in nominal mode and during CPU and memory overclocking. The first mode is interesting because it shows how well the mainboards work with their default settings. It is a known fact that most users do not fine-tune their systems, they simply choose the optimal BIOS settings and do nothing else. That is why we run a round of tests almost without interfering in any way with the default mainboard settings. Since Asus P9X79 Deluxe is the first and so far the only LGA 2011 mainboard we have reviewed at this point, we are going to compare its performance in nominal versus overclocked mode.

We used Cinebench 11.5. All tests were run five times and the average result of the five runs was taken for the performance charts.

We have been using Fritz Chess Benchmark utility for a long time already and it proved very illustrative. It generated repeated results, the performance in it is scales perfectly depending on the number of involved computational threads.

A small video in x264 HD Benchmark 4.0 is encoded in two passes and then the entire process is repeated four times. The average results of the second pass are displayed on the following diagram:

We measured the performance in Adobe Photoshop using our own benchmark made from Retouch Artists Photoshop Speed Test that has been creatively modified. It includes typical editing of four 10-megapixel images from a digital photo camera.

In the archiving test a 1 GB file is compressed using LZMA2 algorithms, while other compression settings remain at defaults.

Like in the data compression test, the faster 16 million of Pi digits are calculated, the better. This is the only benchmark where the number of processor cores doesn’t really matter, because it creates single-threaded load.

Since we do not overclock graphics in our mainboard reviews, the next diagram shows only CPU tests from the 3DMark11 – Physics Score. This score is obtained in a special physics test that emulates the behavior of a complex gaming system working with numerous objects:

We use FC2 Benchmark Tool to go over Ranch Small map ten times in 1920x1080 resolution with high image quality settings in DirectX 10.

Resident Evil 5 game also has a built-in performance test. Its peculiarity is that it can really take advantage of multi-core processor architecture. The tests were run in DirectX 10 in 1920x1080 resolution with high image quality settings. The average of five test runs was taken for further analysis:

In computational tasks where performance depends primarily on the processor frequency, like in the first three benchmarks, the performance gain we got was about 22%. After that the situation changes depending on the specific peculiarities of the test applications. The gain may be lower, like in SuperPi, or higher, like in 7-Zip. However, there was no doubt that the increase in processor and memory frequencies during overclocking will produce a respective increase in performance. We will get more useful information if we compare this system against one of the predecessors. Last time we dealt with a previous generation six-core Core i7-970 processor when we tested Gigabyte G1.Sniper and GA-X58A-OC mainboards. Of course, we had a different testbed and different drivers at that time, but it would still be interesting to see how the performance numbers compare. This comparison will show us the gain from replacing the old six-core LGA 1366 processor with a new LGA 2011 processor with the corresponding complete platform upgrade. It turned out that the new one is about 24% faster than the old one in computational tasks. Overclocking helps the old processor to eliminate the gap and even outperform the new CPU at the nominal frequencies by about 3%. However, LGA 2011 processors also overclock pretty well that is why they still will be about 18% ahead of the old CPUs in an overclocked mode.
