Ryzen 7 5800X3D Spec and Price in the United Kingdom

AM48 cores / 16 threads

Released April 20, 2022 ·

The first desktop chip to ship with AMD's 3D V-Cache: eight cores and 16 threads with 96MB of L3 cache in a 105W TDP, boosting to 4.5GHz from a 3.4GHz base. That's three times the 32MB of L3 on a standard Ryzen 7 5800X, aimed squarely at cache-bound gaming workloads. No integrated graphics is fitted and no cooler is included, so budget for a discrete GPU and cooling separately.

61st of 65 models in the CPU catalog on Boost clock. Tied 12th of 65 models in the CPU catalog on L3 cache — 5 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

  • Notable gaming gains that reach parity with the competing generation, on existing AM4 motherboards.
  • Very energy efficient, with a single-CCX design and no raised power limits versus the standard chip.
  • Owners report large gaming gains from the extra cache, especially in CPU-heavy titles, with less stutter.
  • It is repeatedly described as a drop-in upgrade for existing AM4 systems, needing no new motherboard or DDR5.
  • It runs cool and installs easily, with one owner praising a bundled thermal pad.

Commonly criticised

  • Runs at lower clocks than the standard chip and loses a little application performance.
  • Overclocking is not supported, it costs more than the standard chip, and there is no cooler or integrated graphics.
  • Owners consider it expensive for an older platform, and some note it has held near its launch price.
  • Availability and scalper pricing were concerns around release.
