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 Ryzen 5 1600X is the flagship processor from AMD's latest generation of Ryzen 5 processors which feature the Zen architecture. Following on from last month's release of the Ryzen 7 series, the Ryzen 5 series is positioned as a less expensive mid-performance alternative to Intel's i5 mainstream offerings. Once again, AMD excels in multi-core technology. Like the Ryzen 5 1600, the 1600X features 6 cores and 12 threads, but has roughly 11% higher clock speeds (out of the box) for a 14% premium. Like all Ryzen CPUs the 1600X is unlocked. The 1600X is the only Ryzen 5 CPU with a TDP of 95W, the 1600, 1500X and 1400 all have 50% lower power consumption of 65W. Due to its high thread count, UserBenchmarks show that at stock clocks the 1600X outperforms the i7-7700k on multi-threaded tasks by 23%, but it lags behind by 23% for single and 14% for quad-core performance. The 1600X is priced keenly at $249 so a more appropriate CPU comparison is the i5-7600k where the 1600X wins on stock multi-core by a whopping 81%. The 1600X does represent great value for workstation users that also game but its $30 cheaper sibling, the 1600 (non x version), which includes a cooler and has great overclocking potential out of the box is arguably the the value king in this segment. [Apr '17 CPUPro]
