Intel Core i7-3930K LGA2011 CPU Review

Like the Core i7-3960X Extreme Edition, the i7-3930K achieved a very fast score in our heavily multi-threaded video encoding test, but failed to impress in the less intensively threaded image editing and multi-tasking tests. This means that the i7-3930K could only manage an overall score of 2,252 in our Media Benchmarks, just 2 per cent higher than the quad-core i7-2600K. The simple fact of the matter is that most consumer applications aren't coded to run across 12 threads. As the i7-3930K has such similar specifications as the i7-3960X Extreme Edition it also performed very similarly in professional applications. For example, in Cinebench R11.5 the i7-3930K scored 10.15, which is just 10 per cent slower than the i7-3960X. Using a CPU voltage of 1.4V, a CPU multiplier of 38x, a Base Clock of 123.75MHz, a CPU strap of 125MHz and a memory speed of 1.98GHz, we could also run the i7-3930K stably at 4.7GHz. This overclock provided a substantial boost in performance in every test, allowing the i7-3930K to extend its lead over every other CPU bar the i7-3960X Extreme Edition. This is because the latter has 15MB, as opposed to 12MB, of Level 3 cache. However, when both Sandy Bridge E processors were overclocked, there wasn't much difference in performance. In our Media Benchmarks, for example, the i7-3930K was less than 0.2 per cent slower than the i7-3960X.
