The Intel Core2 Duo E6550 is nearly six years old, the equivalent of around 3 processor lifetimes. This great grand daddy of a processor has been included in the group test as a reference. Intel's Core2 Duo range were hugely successful processors and shipped in over 20 different flavours. In terms of real world performance, with a Passmark-S score of 712 points, the E6550 is less than half as fast as the top of the range i7-3770K Ivy Bridge processor. In recent years emphasis has shifted towards server orientated workloads and on that front the i7-3770K offers over six times more processing throughput. [Feb '12 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 usage. 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) February 2015 CPU Rankings.

Welcome to our desktop CPU comparison. We calculate effective speed which measures performance under typical consumer load. 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. Vote to share your opinion. [CPUPro]
