Intel’s Core i7-9700K is an unlocked 9th generation CPU, released alongside the i5-9600K and the i9-9900K. The 9700K is an 8 core, 8 thread processor based on the third iteration of Intel’s 14nm Coffee Lake architecture, which sees an increase in the number of cores available to mainstream consumers, in line with AMD’s Ryzen 7 offerings. The 9700K features 12 MB of cache, a 95W TDP and Intel UHD graphics 630. And like the other 9th generation chips, it is compatible with Intel’s new Z390 chipset as well as last years Z370 chipset (with an updated BIOS). The 9700K has a base frequency of 3.6 GHz, rising to 4.6 GHz when all 8 cores are engaged and a single core boost frequency of 4.9 GHz (compared to 3.6 GHz, 4.7 GHz and 5.0 GHz for the flagship 9900K). This translates to similar single and quad core performance to the 9900K, but due to the higher number of threads, the 9900K has around a 50% higher multi-core benchmark than the 9700K. Currently most PC games do not engage more than 4 cores, so at $420 (15% cheaper than the 9900K), the 9700K offers better value for money to gamers. If instead, great multi-core performance is a necessity, at $290, the 8 core 16 thread Ryzen 7 2700X is a more prudent choice, with a 30% higher multi-core benchmark than the 9700K.  [Oct '18 CPUPro]

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]
