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]
