The Ryzen 5 7600X3D brings 96MB of L3 cache to a six-core AM5 chip at a 65W rating.
Best for
- 1440p AM5 builds.
Skip if
- Look at the others if this bothers you: 6 cores leave less headroom for streaming alongside games.
Why we like it
It is the cheapest way into AMD's cache-heavy gaming line on AM5. On L3 cache it ties with the Ryzen 7 7800X3D and the Ryzen 7 5800X3D at 96MB. On boost clock it sits mid-pack at 4.7GHz: the Ryzen 7 7700X offers 5.4GHz, and the Ryzen 7 5800X3D comes in at 4.5GHz.
It matches the Ryzen 5 7600 on core count (6 cores). It needs an AM5 board (A620, B650, B850, X670 or X870 series) and DDR5 memory; check the board's CPU support list for the minimum BIOS version. No cooler is included; a single-tower air cooler is enough at its rating. Its price falls between the Ryzen 7 7700X and the Core i5-14600KF, based on our last check.
