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]

The AMD Ryzen 7 1700 is the least powerful of three new Ryzen 7 CPUs. The 1700 model has base and turbo clocks of 3.0 and 3.7 GHz respectively. Both of its more expensive siblings, the 1700X and 1800X, have higher clocks but they also have TDPs of 95 watts whereas the 1700 is rated at just 65 watts. Comparing IPC between Ryzen and Kaby Lake shows that Kaby Lake leads by a maximum of 9% which is great news for workstation users as this allows the 1700 to beat Intel's 6850K in multi-core workloads at almost half the price. Although the 1700 has great IPC it's somewhat limited by its relatively low (by Kaby Lake standards) clock speed which holds it back a little in both gaming and desktop workloads. For multi-core workstation use, the Ryzen 7 1700 represents the best value for money we have ever seen. [Mar '17 CPUPro]
