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 2600, from AMD’s second generation (Zen+) of high-end desktop Ryzen processors, supersedes the first generation Ryzen 5 1600. The newer generation sees a lithography reduction from 14nm to 12nm, but no increase in the number of cores and threads (6 and 12 respectively) over the ground-breaking first generation which continues to surpass similarly priced Intel CPUs in terms of multi-core performance. In other words, progress between generations is predominantly driven by power efficiency and therefore higher attainable clock speeds. The 2600 appears to have a stock base/boost clock of 3.4 / 3.9 GHz compared to the 1600’s 3.2 / 3.6 GHz which is expected to result in a modest increase in effective speed that said, early benchmarks are inconclusive. Included in the expected retail price of about $200 is a Wraith Stealth cooler, so the 2600, like the 1600 before it, represents great value for workstation users. The 2600 compliments the new 400 series motherboards and is also backwards compatible with the 300 series following a bios update. Even though the 2600 is plausible for multimedia production streamers should look elsewhere. Streaming with dedicated hardware such as NVENC or a separate stream PC will nearly always result in fewer dropped frames. [Apr '18 CPUPro]
