Ryzen 9 5900X Spec and Price in Italy

AM412 cores / 24 threads

Released November 5, 2020 ·

A twelve-core, 24-thread step down from the 5950X that keeps the same 105W TDP and 64MB of L3 cache while boosting to 4.8GHz from a 3.7GHz base. No integrated graphics is included, so a discrete GPU is required, and the chip ships without a cooler in the box. Unlocked for overclocking on the AM4, DDR4-3200 platform shared with the rest of the Ryzen 5000 series.

52nd of 65 models in the CPU catalog on Boost clock. 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 1 source(s), reviewed September 13, 2026. A source is counted only where it names this model exactly. How we track prices

Commonly praised

  • Reviewers measured a large generational gain in IPC, gaming and application performance, compatible with existing AM4 boards.
  • It is unlocked, more power-efficient than the prior generation, and adds PCIe 4.0 support.

Commonly criticised

  • It costs more than the previous generation and its multi-CCD layout costs some performance.
  • Overclocking yields little benefit, and it ships with no cooler and no integrated graphics.
