Pros: Brilliant value for money. Cons: It's not the 2400k which can be had for just a tiny bit more and offers a lot more flexibility in terms of overclocking. [Apr '12 CPUPro]

MORE DETAILS

Intel’s Core i7-9700K is an unlocked 9th generation Coffee Lake CPU. It is an 8 core, 8 thread processor. The 9700K features 12 MB of cache, a 95W TDP and Intel UHD 630 graphics. 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 stock base / boost clocks of 3.6 / 4.6 GHz and a single core boost of 4.9 GHz (compared to 3.6, 4.7 and 5.0 GHz for the flagship 9900K). This translates to almost identical single, quad and octa core performance between the 9900K and 9700K. Mainstream PC games do not benefit from more than six threads, so at $350 (25% cheaper than the 9900K), the 9700K offers far better value for money to gamers. That said gamers have very little reason not to consider the i5-9600K which, when overclocked, offers almost equivalent performance at a 35% discount[Oct '18 CPUPro]
