The Core i5-3570K Ivy Bridge processor is one of Intel's best performers to date. In terms of real world performance this processor offers far more than most users are likely to ever need. Scoring 2012 points on the PassMark Single Thread benchmark, the 3570K is within a few percent of the fastest processors currently available and at 77 watts TDP it's no energy hog either. The server orientated GeekBench and PassMark scores of 13920 and 7144 put the 3570K at just over the 50% marker in terms of total processing capacity compared to the other processors in the group test. For server based workloads more performance is available from the Core i7 range of processors but for typical consumer use this processor is already far more powerful than it needs to be. [May '13 CPUPro]

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]
