Ryzen 9 7900X3D

Released February 2023

A 12-core Zen 4 desktop processor for AM5 with 3D V-Cache for gaming.

Cores: 12/24
Boost: 5.6 GHz
L3: 128 MB
Power: 120 W
Socket: AM5

What reviewers say

Strong gaming and excellent efficiency, but lower application performance than 7900X and awkward launch value between 7800X3D and 7950X3D. Its cache chiplet has only six active cores; correct driver scheduling matters. Better suited to mixed work at a discount than a pure gaming build.
