What reviewers say

Reviewers agree it is the most powerful all-round desktop processor, nearly matching the Ryzen 7 9800X3D in games while keeping the 16-core Ryzen 9 9950X's performance in creative work; Club386 also found it cool and efficient. The common drawback is the high price, with the 9800X3D better value for gaming alone, and PC Gamer noted some quirks from its two-chiplet design.
