The i9-11900K is the fastest CPU in Intel’s 11th Gen Rocket Lake-S lineup which brings higher IPC (early samples indicate +19%) and 50% stronger integrated graphics. There are also 500 series chipset improvements including: 20 PCIe4 CPU lanes (up from 16) and USB 3.2 Gen 2x2 (20 Gbps up from 10 Gbps). Rocket Lake’s IPC uplift 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]

Intel’s Alder Lake i5-12400F offers six hyper-threaded performance cores at an MSRP of just $180 USD. This represents excellent value for consumers and, in particular, gamers. It has a boost frequency of 4.4 GHz, 18 MB of L3 cache and a TDP of 65W. The F-version of the CPU does not have integrated graphics, however this will be of little concern to gamers with discrete GPUs. Whilst Intel’s overclockable i5-12600K has four additional efficiency cores and offers around 12% more performance than the 12400F, it also costs around 50% more. The 12400F offers great value, but to achieve optimal performance the requisite B660 motherboard (which supports 3200+ RAM) is, at least for now, difficult to find at reasonable ($150 USD) prices. AMD’s top value hex-core Ryzen 5 5600X offers similar performance for 50% more money. Despite Intel’s price / performance lead, AMD’s prolific marketers (forums, youtube, reddit etc.) have historically outsold Intel whilst carrying a similar handicap. [Jan '22 CPUPro]
