The Intel Core i5-4670K is the latest middle tier desktop processor from the fourth generation of Intel's Core range codenamed "Haswell". In terms of raw performance this processor slightly bests its predecessor the 3570K achieving approximately 10% higher server benchmark scores. In terms of real world performance the single core improvements are more relevant as more than two cores are rarely used for most typical consumer tasks and these have also improved by around 10% over the 3570K. It's not all good news though as the price increase of 14% more than offsets the performance improvements. This processor currently represents approximately the same value for money as its predecessor, the i5-3570K. [Jun '13 CPUPro]


The FX 6-Core, like most CPUs from AMD, delivers reasonably good server orientated multi threaded performance and consequently good processing thoughput at a reasonable price tag. Where the FX 6-Core lacks is in the area of single core performance which although not normally a major problem for server workloads, is always very relevant to desktop users. The overall performance of the FX 6-Core is comparable to Intel's five years younger Core i7-950. There are server orientated use cases where the FX 6-Core will excel thanks to its excellent overall throughput and in those instances the FX 6-Core represents good value for money. But typical desktop users will find far better value elsewhere[Sep '13 CPUPro]


Processor User Rankings (Charts) August 2015 CPU Rankings.

Welcome to our desktop CPU comparison. We calculate effective speed which measures real world performance for typical consumers. Effective speed is adjusted by price to yield a value for money rating. Calculated values don't always paint the whole picture so we check them against hundreds of individual user ratings. The customizable table below combines these factors and more to bring you the definitive list of top CPUs. [CPUPro]
