The Core i7-3630QM has been included in the CPU group test as a reference Mobile CPU. This third generation Ivy Bridge processor has proven hugely successful and powers a significant proportion of today's high end laptops. Compared to desktop processors certain compromises have to be made and that is clear from the benchmarks. In terms of real world horsepower the i7-3630QM is comparable to first generation, and three years older, Core i7 Desktop processors. Where the Mobile processors excel is on energy efficiency and with a TDP of just 45 watts the 3630QM is the least power hungry processor in the group test. [Feb '12 CPUPro]

MORE DETAILS

The Intel Core i5-6600K is based on the new "Skylake" 14nm manufacturing process. Sporting 4 physical cores with base/turbo clocks of 3.5/3.9 GHz the 6600K and its predecessor, the 4690K share the same basic configuration and disappointingly, offer similar performance. Comparing the 6600K and 6700K shows that the 6700K has faster multi and single core performance. The improved multi core performance is due to Hyperthreading which is the key differentiator for the i7-6700K. The gap in single core performance can largely be eliminated by overclocking the i5-6600K so although the stock effective speed is significantly higher on the 6700K, this gap diminishes significantly when both processors are overclocked. At a 30% discount, the 6600K is the better value gaming CPU. [Aug '15 CPUPro]
