The flagship in the new lineup is the Core i7-8700K. It is a 6C/12T beast, with a base clock of 3.7GHz, a boost clock of 4.7GHz, and 12MB of Intel Smart Cache. The Core i5-8400 features the same physical die, but has only 9MB of Smart Cache, no Hyper-Threading, and base and boost clocks of 2.8GHz and 4GHz, respectively. The entire line-up features more cores, support for faster memory speeds, and leverages a fresh platform that's been tweaked for more robust power delivery and, ultimately, more performance. The Core i7-8700K proved to be an excellent performer, besting every other processor in single-threaded workloads and competing favorably with 8C/16T Ryzen 7 processors. The affordably-priced 6-core Core i5-8400 even managed to pull ahead of the quad-core Core i7-7700K in some tests. Overall, performance is strong, especially for games, and the processors seem to be solid values in their segment.
