R1
The short version
The Ryzen 5 8400F is a six-core, 12-thread AM5 processor with 16 MB of L3 cache and no integrated graphics, so a discrete card is required. It is a low-cost way onto AM5, but PCIe 4.0 and the small cache temper the case, and reviewers split on whether it beats cheaper AM4 options.
Pros
- Six cores on AM5 at a 65 W TDP
- AM5 platform with DDR5
- Unlocked per AMD's page
Cons
- No integrated graphics
- PCIe 4.0 only with 20 lanes
- Only 16 MB of L3 and a 4.7 GHz boost
- Some reviewers question its value
