Verdict

The Intel Core i7-4790K, codenamed 'Devil's Canyon', is a 4th generation quad-core desktop processor built on a 22nm Haswell architecture for the LGA 1150 socket. It features a base clock frequency of 4.0 GHz, a Max Turbo frequency of 4.4 GHz, 8 MB of Intel Smart Cache, and 8 threads via Hyper-Threading technology. Key pros include its high out-of-the-box clock speeds—making it one of the fastest consumer quad-cores of its era—and improved thermal interface material (NGPTIM) for better heat management compared to the i7-4770K. However, it carries a higher 88W TDP and, despite its 'K-series' unlocked status, many users found its additional overclocking headroom limited as power consumption and temperatures spike sharply beyond stock settings.
