CPU Comparison
Intel Core i7-4790K vs Intel Core i5-4590S
A side-by-side comparison of specs, performance and value. The Intel Core i7-4790K is an unlocked desktop processor launched in May 2014 as the flagship of the 'Devil's Canyon' refresh. Built on the 22nm Haswell process, it features 4 cores and 8 threads, operating at an impressive base clock of 4.0 GHz and boosting up to 4.4 GHz. The 'K' suffix denotes an unlocked multiplier, making it a favorite among overclockers. It includes 8MB of L3 cache and supports dual-channel DDR3 memory. With an 88W TDP, it fits into the LGA 1150 socket. The processor integrates Intel HD Graphics 4600. The 4790K addressed the thermal issues of the 4770K by using improved thermal paste, allowing for higher sustained clocks and better overclocking headroom. It remains a beloved classic that provided immense performance for gamers and enthusiasts.

Our Verdict on Each
A legendary CPU that was the first to hit 4.0 GHz base. It still holds up for basic use but is outdated for modern gaming.
Best for: The Core i7-4790K is a legendary processor that should only be considered today if you are maintaining an existing LGA 1150 system. It still offers decent performance for basic computing and older games, and its unlocked multiplier allows for some overclocking fun. However, it is not recommended for new builds. The lack of Windows 11 support, high power consumption, and outdated instruction sets make it a poor choice for modern workloads. If you are building a budget PC, modern processors offer vastly superior performance and efficiency.
