Intel’s Comet Lake flagship, the i9-10900K, is the fastest gaming and desktop CPU currently available. This ten-core hyperthreaded processor can easily be overclocked so that all twenty threads run at an eye-watering 5.2 GHz. Whilst its stellar performance is second to none, it comes with a premium price tag of $488 USD. The 10900K also requires a new (Z490) LGA1200 motherboard, which Intel has indicated will remain compatible with Rocket Lake CPUs which are due later this year. Whilst AMD’s competing $420 USD Ryzen 3900X and $675 USD Ryzen 3950X do have a greater number of cores, their lower clock speeds and higher memory latency handicap them in non-rendering use cases. Overall, the 10900K has a 16% effective speed advantage over both the 3900X and 3950X. Users that do a lot of rendering should investigate dedicated hardware encoders such as NVENC and Quick Sync as these are far more efficient than CPU based rendering. Comparing the 10900K and 10700K shows that, when paired with a 2060S, the 10700K offers comparable gaming performance for 20% less money. [Jun '20 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]
