The Intel Core i7-5820K is the cheapest of three (5820K,5930K,5960X) new Haswell-E prosumer/enthusiast processors. The 5820K sports six physical cores and twelve threads which allow for enormous processing throughput. Unfortunately Intel have somewhat handicapped the 5820K by setting its base clock at just 3.3 GHz, 0.7GHz lower than the class leading 4790K. Comparing the 4790K and 5820K shows that the cheaper i7-4790K is significantly faster at both single and dual threaded workloads. The additional two cores found in the 5820K are not relevant to general computing and as such the 5820K probably makes a better server rather than consumer proposition. The Haswell-E X99 architecture also requires DDR4 RAM which is currently far more expensive than DDR3. Overall the 5820K is a very expensive option and probably best avoided by the vast majority of consumers.  [Sep '14 CPUPro]
