The Intel i9-9900K is an 8 core, 16 thread, unlocked 9th generation Coffee Lake processor. It has a base / boost clocks of 3.6 / 4.7 GHz and a single-core boost of 5.0 GHz (the highest frequency achieved yet from this class of Intel CPU). It features 16 MB of cache, a 95W TDP and Intel UHD 630 graphics. The 9900K is compatible with the new Z390 chipset, and subject to a BIOS update, is also compatible with the older Z370 chipset. Aimed at users who do not wish to compromise, the i9-9900K offers the best gaming and desktop experience available at any price. Heavy workstation users should consider the Ryzen 9 3900X which is similarly priced. Comparing the overclocked 3900X shows that it is just 10% worse for gaming and desktop (sub octa-core) but around 40% better for 64-core computations. Gamers should consider the 9700K which offers identical overclocked gaming performance at a $100 USD discount. [Oct '18 CPUPro]

The i5-11600K is the best value "top tier" CPU in Intel’s 11th Gen Rocket Lake-S lineup. With a simple overclock it offers almost the same levels of performance as the 11900K. Rocket Lake brings higher IPC (early samples indicate +19%) which translates to around a 10% faster Effective Speed than both Intel's 10th Gen and AMD’s 5000 series. Despite Intel’s performance lead, AMD continues to outsell Intel. Given the scale of Intel's operation, it’s inexplicable that their marketing remains so neglected. Little effort is made to counter widespread disinformation such as: “it uses too much electricity” or the classic: “it needs more cores”. Intel’s marketing samples are routinely distributed to reviewers that appear better incentivized to bury Intel's products rather than review them. Not enabling XMP or only testing with BIOS power limits enabled is akin to leaving the handbrake on during a race. Mind-numbing “scientific” and rendering benchmarks are presented as gospel. Different games, mostly unplayed by real users, are cherry picked for each “review”. When it's convenient, canned game benchmarks are chosen such as Ulletical’s CSGO which runs at nearly double the in-game fps. Credible benchmark data, which necessarily includes replicable video footage from popular games, is the exception rather than the rule. At every release, AMD’s marketers coordinate narratives to ensure another feast of blue blubber. Nonetheless, towards the end of 2021, Intel’s Golden Cove is due to offer an additional 20-30% performance increase. At that time, with a net 30-40% performance lead, Intel will probably regain significant market share despite AMD's class-leading marketing. In the meantime, most PC gamers need look no further than the 11400F. [Mar '21 CPUPro]
