What reviewers say

Reviewers agree it is Intel's best desktop processor and excellent value, with class-leading multi-core performance and improved gaming at a much lower price than the chip it replaces. Common reservations are that AMD's X3D chips remain faster in games and the LGA 1851 platform has no upgrade path; Tom's Hardware and PC Gamer found it power-hungry, while Club386 rated its efficiency highly.
