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]

Intel’s Core i3-9100F is a quad-core 9th generation Coffee Lake desktop processor. It features base / boost clocks of 3.6 / 4.2 GHz, 6 MB of cache, a 65W TDP and it ships with a cooler. Gamers should pair the 9100F with a Z390 motherboard and unlock higher XMP RAM speeds. This will deliver up to a 15% fps boost which is well worth it considering that many Z390 boards are available for around $100 USD (here is one of the builds from our EFps test lab). The 9100F has great single core performance coupled with a strong memory sub system. This enables it to deliver excellent all round performance, easily holding its own against far pricier CPUs for the majority of use cases. The heavily hyped 12 threaded 6 core Ryzen 3600, paired with a 2060S, barely pulls ahead in any of the top five games. [Oct '19 CPUPro]
