Of course, things are going to change dramatically during overclocking, because Asus Sabertooth Z77 had the lowest overclocking result of all the testing participants. The obtained results are summed up in the following table:
Asus Sabertooth Z77 is quite logically the slowest during most of the tests in overclocked mode, but as it turned out not in all of them.
Intel mainboards fell behind Asus Sabertooth Z77 in 7-zip test, because it is very sensitive to the memory sub-system parameters, and the memory timings on Intel mainboards are not as good as on others. MSI board was the slowest in 3DMark 11 – Physics Score test. As for the gaming tests, here Asus Sabertooth Z77 is barely any different from the other boards that reached 4.6 GHz CPU clock, and all others fall farther behind. So, CPU overclocking is definitely not the only thing affecting the overall system performance. Sometimes mainboards’ unique features have a much greater effect on the speed.
