Ryzen 9 7900X Spec and Price in the United Kingdom

AM512 cores / 24 threads

Released September 27, 2022 ·

A twelve-core, 24-thread step down from the 7950X that keeps the same 170W TDP and 64MB of L3 cache while boosting to 5.6GHz from a 4.7GHz base. The higher base clock than the 16-core flagship suits workloads that don't scale past twelve threads. Unlocked for overclocking and sold without a bundled cooler, on the same AM5, DDR5 platform as the rest of the 7000 series.

Tied 10th of 65 models in the CPU catalog on Boost clock — 7 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 13, 2026. A source is counted only where it names this model exactly. How we track prices

Commonly praised

  • Impressive improvements across the board, with great gaming performance.
  • PCIe 5.0 support, integrated graphics, an unlocked multiplier, and no E-cores to complicate scheduling.
  • Owners describe it as very fast for both gaming and heavy productivity workloads.
  • It is reported as a large upgrade from older processors, and it responds well to PBO and Curve Optimizer tuning.

Commonly criticised

  • A high total platform cost, with demanding cooling needs at high temperatures.
  • The second core complex runs at lower clocks, and communication between the two costs a little performance in some workloads.
  • By default it targets a 95C thermal limit, and owners say it needs strong cooling.
  • The AM5 platform is called expensive, with high motherboard and DDR5 costs at launch.
  • One owner reports higher idle power than an older AM4 system.
