The Intel Core i7-4790K, codenamed Devil's Canyon, is an upgraded 4770K, Intel's current flagship i7. The 4790K features an improved thermal interface which enables it to dissipate heat more efficiently than the 4770K. Comparing the 4770K and 4790K shows that stock performance has improved by 13% which is consistent with the base clock jump from 3.5 GHz to 4.0 GHz. OC performance remains unchanged. Comparing the 4790K and 4790 shows that at stock clocks the 4790K is around 16% faster which considering the small price difference makes the 4790K a far better choice. Previously Intel targeted the unlocked K versions at overclockers but with Devil's Canyon they have included VT-d on the K chip and this time it's squarely aimed at both power users and overclockers alike. Until the release of Broadwell in six months, the 4790K is the high end CPU of choice. [Jul '14 CPUPro]

Early Q3 of 2019 welcomes the Ryzen 9 3900X, AMD’s current top of the range, third generation Ryzen flagship which raises the bar for 64-core processing on desktop CPUs. This is AMD’s first Ryzen 9 processor and it is a 12-core, 24-thread CPU based on their latest 7nm Zen 2 microarchitecture. The 3900X has a boost/base clock of 3.8/4.6 GHz, 64 MB of L3 cache (double the L3 on the rest of 3000 series), support for 3200 MHz DDR4 system memory and a TDP of 105W. All this, plus a Wraith Prism cooler, at a very reasonable launch price of $499 USD. By comparison, Intel’s 8-core, 16 thread i9-9900K is available for $479 USD (and requires a cooler: $30+ USD). Benchmarks illustrate that the overclocked 3900X leads by a whopping 41% for 64-core processing but that the 9900K maintains a 10% lead for gaming, desktop and other sub octa-core tasks. The 3900 memory controller is significantly improved over previous Ryzen iterations and shows a better write throughput than the lower spec 3000 models, but it still shows relatively high latency which can impact gaming. In terms of 64-core performance at this price point, there is no threat from Intel. The only real competitor is the upcoming (Q4, 2019) 16-core, 32-thread 3950X ($749 USD). The Ryzen 9 3900X is compatible with the new PCIe 4.0 enabled X570 motherboard via an AM4 socket, as well as 400 and 300 series motherboards. [Jul '19 CPUPro]
