What the sales show
About 4 sales a week in the four weeks to 21 Oct.
Before you buy or sell a used i5-9600K
Verify if the listing is this i5-9600K with integrated graphics or the i5-9600KF without video output, as the two are separate parts, alongside the locked 65W i5-9600. Six cores and six threads reach a 4.6GHz boost at 95W.
No cooler comes in the retail box, and overclocking requires a Z390 motherboard or a BIOS-updated Z370 board with DDR4 RAM. Older 100 and 200-series LGA1151 sockets are incompatible with all 9th-gen chips.
