Intel are celebrating the 40th anniversary of their x86 architecture and 8086 processor with the launch of their high-end i7-8086K. Just 50,000 units of this hex core, twelve threaded Coffee Lake processor have been made available globally. Exactly like the i7-8700K, the 8086K features 12MB of smart (L3) cache, 2 channels of DDR4 RAM and has a TDP of 95W. Essentially, the 8086K is Intel’s current Coffee Lake flagship, the i7-8700K, with a single-core turbo frequency factory overclocked by 300 MHz. Thermals permitting, out of the box, the i7-8086K achieves a single core boost speed of 5.0 GHz – which is a new record for Intel. That said, you would be unlucky if you were unable to achieve a 5.0 GHz single core OC with an 8700K. For everything other than single core, the turbo clock speeds on the 8086K exactly match the 8700K which puts the 8086K firmly into gimmick territory. Directly comparing the 8086K and 8700K shows that for a $100 (24%) price premium you get around a 5% performance improvement which drops to around 2% when both chips are overclocked. If the price gap between the 8086K and the 8700K were to fall to less than 20 USD it may be worth considering the 8086K. [Jun '18 CPUPro]

The Rocket Lake i5-11400F paired with a B560 motherboard and 3200 RAM ($365 USD) offers unprecedented value for money to gamers. It completely prices AMD's 5000 series out of the market. 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]
