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]

Gaming is more accessible with the i3-12100F: Intel’s entry level Alder Lake desktop processor. Higher end Alder Lake processors feature a combination of performance and efficiency cores, however, the 12100F contains just four hyper-threaded Golden Cove performance cores. It has a max boost frequency of 4.3 GHz, 12 MB of L3 cache and a 58W TDP. The 12100F is keenly priced at around $130 USD and needs to be paired with a new chipset such as the B660. Only users with discrete GPUs should consider “F” models as they do not have integrated graphics. Whilst a budget PC built around the 12100F represents unbeatable value for money, the 6-core i5-12400F, with 50% stronger multi-core, is a better option for gamers with 3060+ tier GPUs. AMD do not have any CPUs competing in this price segment. Entry level gamers, who cannot find reasonably priced discrete GPUs, could consider the similarly performing Ryzen 5 5600G APU which has integrated RX Vega graphics that are around three times faster than Intel's UHD 730. [Jan '22 CPUPro]
