What reviewers say

Both reviews found leading performance in their launch tests, but only small gains over the 13900K and substantial cooling demands. Tom's Hardware considered the premium poor value, while HotHardware was more accepting of its appeal to enthusiasts seeking Intel's fastest chip at the time.
