Verdict

The Intel Core i5-7400 is a 7th-generation 'Kaby Lake' desktop processor launched in Q1 2017, featuring 4 cores and 4 threads with a base clock of 3.0 GHz and a max turbo frequency of 3.5 GHz. Built on a 14nm process with a 65W TDP, it includes 6MB of Intel Smart Cache, supports up to 64GB of DDR4-2400 or DDR3L-1600 RAM, and integrates Intel HD Graphics 630. Main pros include its energy-efficient 65W power draw, reliable 1080p performance for general tasks or budget gaming, and solid thermal management with stock cooling. However, its primary cons are the lack of Hyper-Threading, a locked multiplier that prevents overclocking, and its status as a discontinued product that is officially unsupported by Windows 11.
