Manufacturer description
The Intel Core i7-4790K is the fastest LGA1150 chip Intel ever shipped, and it remains the go-to upgrade for anyone still running a Haswell board. Four cores, eight threads, 8MB of cache, and boost clocks up to 4.40 GHz give this Devil's Canyon processor the single-thread speed that older games and legacy software actually reward. The unlocked clock multiplier means you are not locked to stock behavior: pair it with a Z97 motherboard and a decent cooler, and you control the tuning yourself. Socket FCLGA1150 compatibility makes this a genuine drop-in path for aging Core i5 builds, no new…
SpecPicks Verdict
SpecPicks scored Intel Core i7-4790K Processor BX80646I74790K using a rating × review-volume × price-fit model applied to published specs and reviews across the processors category. Intel's processors lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.
Common buyer scenarios for processors of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent.
