What reviewers say

Reviewers agree it is strong in multi-threaded and rendering work and draws much less power than Intel's previous chips, especially in games. The common criticism is gaming performance that falls behind the Core i9-14900K and AMD's chips, alongside the cost of moving to a new platform; PC Gamer found it still less efficient than AMD's Zen 5.
