Intel Core i7-4790K

4C/8T · 4.4 GHz · 88 W

The Core i7-4790K was the flagship of Intel's Devil's Canyon refresh, a mid-life update to the 4th generation Haswell desktop line that raised clock speeds and improved thermals with a better thermal interface material and extra on-package decoupling capacitors. It was the first Intel desktop processor to ship with a 4.0 GHz base clock, and its four cores with Hyper-Threading kept it a popular gaming chip for years after launch.

Notes: Microsoft's supported processor lists for Windows 11 24H2 and 25H2 start at 8th Gen Intel Core, so this 4th Gen part is not supported; Windows 10 is. Microsoft has not published a separate processor list for Windows 11 26H2, so the 25H2 status is carried over. Mainstream Linux distributions and ChromeOS Flex are supported.
