Ryzen 9 7900 Spec and Price in the United States

AM512 cores / 24 threads

Released January 14, 2023 · $429.00 MSRP

A 65W alternative to the 170W Ryzen 9 7900X, cutting the TDP by more than half while keeping the same twelve cores, 24 threads and 64MB of L3 cache. Boost clock drops to 5.4GHz and base clock to 3.7GHz to fit the lower power envelope, a trade aimed at quiet or small-form-factor builds rather than peak throughput. Unlocked for overclocking on the same AM5, DDR5-5200 platform as its X-series counterpart.

Tied 23rd of 65 models in the CPU catalog on Boost clock — 8 models share this figure. Tied 17th of 65 models in the CPU catalog on L3 cache — 7 models share this figure.

Guides for this category

How to choose a desktop CPUA chip's socket decides what it can go into; cores, cache and TDP decide what you actually get once it's installed.How many CPU cores you actually needWhy more cores is not more speed, how gaming and productivity ask for cores differently, and why a core count alone never ranks two chips.When a CPU price is actually goodWhy a chip's list price and discount percentage tell you little, what a processor's price does over its life, and how to read its tracked history.Laptop CPU vs desktop CPUA mobile chip with the same core count is not the same processor — what the power envelope changes, and why these parts carry no price.

What owners and reviewers say

Summarised from 2 source(s), reviewed September 14, 2026. A source is counted only where it names this model exactly. How we track prices

Commonly praised

  • Reviewers highlighted its exceptional performance per watt, calling it among the most efficient desktop CPUs tested, helped by the bundled Wraith Prism cooler.
  • Testers found it could hit a peak boost near 5.45GHz and stayed easy to cool at its 65W TDP, making it suited to small-form-factor builds.
  • It offered strong multi-threaded capability and low power draw for its 12-core core count.

Commonly criticised

  • Its all-core boost of about 4.3GHz left out-of-the-box multi-threaded performance behind the higher-powered 7900X.
  • In games it trailed cheaper CPUs, with the Core i7-13700K ahead in the titles tested.
  • Its street price sat close to the higher-binned 7900X, so the savings were small.
