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 9 5900X is second in AMD’s line-up of new Zen 3 CPUs. The 12-core hyper-threaded processor has base/boost clock speeds of 3.7/4.8 GHz, a 70 MB cache and a TDP of 105W. The 5900X took center stage in the 5000 series launch presentation where AMD gunned for Intel’s “best gaming CPU” crown. They showed the 5900X as being 26% better for gaming than the previous generation’s Ryzen 9 3900XT, attributing this to the new architecture’s faster single core speeds and lower latency. AMD also stated that the 5900X achieves, on average, 6.8% faster gaming performance than Intel’s 10-core i9-10900K. The details around AMD’s testing were not disclosed but it is safe to assume that 6.8% is the highest average lead that AMD are willing to stand by. Our benchmarks show that the 5900X’s slightly faster cores and the 10900K’s slightly lower memory latency balance out to yield similar performance. Whilst presenting their figures, AMD admitted that their 3000 series CPUs were far from “best for gaming” and conceded that the 10900K is approximately 19% faster than the 3900XT (our effective speed marks the gap at just 14%). Despite this clear performance deficiency, AMD supported 3000 series sales with an aggressive and successful marketing campaign to easily outsell Intel over the last 12 months. Given the real performance uplift observed in the 5000 series, and the absence of any meaningful marketing from Intel, we expect CPU sales to shift even further in AMD’s favour. Gamers that do not wish to pay “marketing fees” should investigate Intel’s $175 USD 11400F, the $660 USD savings would be far better spent on a higher tier GPU. ^{[Nov '20 CPUPro]}
