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]}

Early Q3 of 2019 sees the release of the new Ryzen 5 3600X: a hex-core, 12-thread processor. AMD are releasing five new CPUs based on their latest Zen 2 microarchitecture which delivers approximately 13% better IPC than the previous 12nm Zen+. For workstation builds the 3600X is viable, however, the $200 USD Ryzen 5 3600 represents a far better value proposition. The additional $40 USD for the 3600X basically buys a better cooler (Spire vs Stealth). This allows for an extra 200 MHz of extra base and boost clock: 3.8 / 4.4 GHz on the 3600X vs 3.6 / 4.2 GHz on the 3600, this translates to approximately 2% higher overclocked performance for 20% more money. Neither of the stock coolers on the 3600 or 3600X are as effective as a $20 USD aftermarket cooler such as the Gammaxx 400. The 3600 with a Gammaxx 400 outperforms the 3600X with a Spire cooler and when both use a Gammaxx 400 they are more or less identical. The 3600X SKU is basically a marketing gimmick designed to milk unsuspecting consumers. Comparing the 3600X to Intel’s overclocked flagship i5-9600K shows that although the 3600X has 29% faster 64-core speed, it is around 11% worse for gaming (sub eight core performance). Additionally, the 3600X's memory controller, although significantly improved over previous Ryzen iterations, still has limited bandwidth and high latency which can also impact gaming. The arrival of Zen 2 marks the end of the "Sandy Bridge (i5-2500K)" era, Intel can no longer rely exclusively on their single-core advantage to dominate the market, they must also compete on price. ^{[Jul '19 CPUPro]}
