Performance and Power Consumption during Overclocking

Just like during the performance comparison in the nominal mode, ASRock X58 Extreme will be competing against Gigabyte GA-EX58-Extreme:

It is not quite clear why ASRock X58 Extreme outperforms its rival in Custom PC Bench 2007 tests, for instance. Both mainboards worked in identical testing conditions, only memory timings on Gigabyte mainboard were a little better. Other than that, the results turned out quite predictable. In those applications that do not depend on the memory subsystem performance too much, both boards performed equally fast. Take, for example, Cinebench 10 and Fritz Chess Benchmark. In gaming tests ASRock X58 Extreme falls a little behind, though the difference is not critical - only 3-5 %.

The results of power consumption tests look worse for ASRock X58 Extreme, although in nominal mode it was just as energy-efficient as Gigabyte GA-EX58-Extreme.

In idle mode and under single-threaded load the power consumption of both mainboards is again at comparable levels. However, as the workload increases, so does the difference between the boards reaching 50 W maximum. It is a lot and I assume that ASRock X58 Extreme owes this high power consumption to increased CPU Vcore when “ASRock VDrop Control” function is enabled.
