AMD Ryzen 7 5800X
A fast, hot 8-core AM4 chip; gamers on AM4 get more from the X3D models.
The short version
- AM4 owners upgrading from an older Ryzen chip without changing board or memory
- People who game and also stream or encode video
- Builders who already own a strong air or liquid cooler
- You only game and can get a 3D V-Cache AM4 chip for similar money
- You are starting a fresh build and want an upgrade path; look at AM5
- You have no graphics card or no aftermarket cooler
What owners like
- Strong single-core speed and gaming performance for its generation
- Good power efficiency next to Intel's 8 and 10 core chips of the same era
- Room to overclock, with KitGuru reaching 4.7 GHz on all cores
Common complaints
- Runs hot because most of its power goes through one chiplet; KitGuru saw just over 80 C under load on a 280 mm liquid cooler
- No cooler in the box, so a capable aftermarket cooler adds to the cost
- Priced awkwardly between the Ryzen 5 5600X for gaming and the Ryzen 9 5900X for heavy multi-core work
Based on KitGuru and Gizbot reviews, Notebookcheck's spec and benchmark page, and the Newegg product listing.

What it does
An 8-core, 16-thread Zen 3 desktop processor for AM4 motherboards, sold without a cooler.
- Eight cores and 16 threads on a single chiplet with a shared 32 MB L3 cache
- Unlocked for overclocking
- PCIe 4.0 support for fast SSDs and graphics cards
- Fits AM4 boards, including 500 series boards
- No integrated graphics, so a separate graphics card is required
A strong 8-core chip for gaming and streaming on an existing AM4 board with DDR4 memory. The trade-offs are heat and positioning: all eight cores sit on one chiplet, so it runs hot and needs a good cooler, and reviewers felt it was squeezed between the cheaper Ryzen 5 5600X and the stronger Ryzen 9 5900X. For pure gaming on AM4 today, the 3D V-Cache chips are the better buy.

Questions
Does the Ryzen 7 5800X come with a cooler?
No. It ships without a cooler, and reviewers recommend a good aftermarket cooler because the chip runs warm.
Does the Ryzen 7 5800X have integrated graphics?
No. It has no built-in graphics, so you need a separate graphics card.
Why does the Ryzen 7 5800X run so hot?
All eight cores sit on one chiplet, so its power is concentrated in a small area. KitGuru measured just over 80 C under heavy load with a 280 mm liquid cooler. The listed maximum is 90 C.
Is the 5700X3D better than the 5800X for gaming?
Usually yes. The X3D chips add a large stacked cache that helps in games, while the 5800X has higher clocks for other work.
What memory does the Ryzen 7 5800X use?
DDR4, rated up to DDR4-3200.
