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 6 core, 12 thread Ryzen 5 2600X is one of four new AMD second generation of high-end desktop Ryzen processors (codenamed Pinnacle Ridge) renowned for excellent value multi-core performance. The 2600X is set to replace the also 6 core, 12 thread 1600X as AMD’s new mid-range Ryzen 5 flagship. The latest generation of CPUs features a matured Zen+ chip architecture with 12nm lithography, increased clock speeds and Precision Boost 2 technology designed to leverage more CPU power than per the first generation. The 2600X appears to have stock base / boost clock speeds of 3.6 / 4.2 GHz. This is only marginally faster than the 1600X’s 3.6 / 4.0 GHz. Modest effective speed improvements are expected, although further benchmarks are necessary to draw firm conclusions. The 2600X ships with a Wraith Spire cooler and is priced reasonably at an expected $250. However, for most use cases, the new lower clocked Ryzen 5 2600 at $200 represents better value for money. Pinnacle Ridge processors are designed to work with the new 400 series motherboards, which allow for greater overclocking head room, and they are also backwards compatible with the 300 series motherboard following a bios update. [Apr '18 CPUPro]
