The FX-8320E is a Vishera eight core processor based on AMD’s Piledriver architecture. The ‘E’ in the FX-8320E denotes energy efficiency with the FX-8320E boasting a TDP of 95 Watts which is relatively low for FX processors. The FX-8320E was launched in September 2014 at the same time as the FX-8370E. Comparing the 8370E and 8320E shows that the performance profiles are similar with the 25% more expensive 8370E edging ahead, particularly on single core workloads. The 8370E is clocked slightly higher with base/turbo frequencies of 3.3/4.3 GHz versus the 8320E’s 3.2/4.0 GHz. Overall the 8320E scores a mediocre effective speed of 70. Whilst this is sufficient for the majority of desktop applications: web-surfing, word-processing and playing movies, better single-core performance is offered by any number of Intel processors. [Dec '14 CPUPro]

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]
