The Core i7-6900K is one of four new Broadwell-E prosumer CPUs. This model has eight cores with base and turbo frequencies of 3.2 and 4.0 GHz respectively. The 6900K is based on a 14 nm architecture, it has a TDP of 140 watts, 40 PCIe 3.0 lanes and no integrated graphics. Because of its MSRP of $1,100, the 6900K only makes sense for very niche use cases which include top end graphics design and video production. Comparing the 6900K and 6700K shows that for typical desktop use the 6900K only offers a gain of around 12% for a whopping three fold price increase. This is because desktop computing largely depends on single core performance and the Skylake i7-6700K is both clocked higher and has higher IPC due to its one generation lead over the 6900K. That said, as a workstation CPU the 6900K is bested only by the $2,000 flagship ten core 6950X. (6900K vs 6950X) ^{[Jun '16 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]}
