AMD Ryzen 5 8400F
The Radeon-less sibling of the Ryzen 5 8600G: the same six full-speed Zen 4 cores and 16 MB of L3 cache, clocked slightly lower (4.2/4.7 GHz base/boost vs. the 8600G's 4.3/5.0 GHz) and minus the integrated GPU, launched quietly months later at a lower price. Buy it when a discrete graphics card is already going in the build; buy the 8600G instead if the iGPU is needed as a fallback.
Pros
- Six full-speed Zen 4 cores at a 65 W TDP, with a Wraith Stealth cooler included, at the lowest price in the Ryzen 8000 desktop lineup
- Identical CPU cores and cache to the Radeon-760M-equipped 8600G (clocked slightly lower at 4.2/4.7 GHz vs. 4.3/5.0 GHz), just without the integrated graphics — no premium paid for a GPU that goes unused in a build with a discrete card
- Unlocked multiplier and AMD EXPO memory-overclocking support
- Full 20 native PCIe lanes (16 usable) and a 256 GB max memory rating, matching the higher-end 8000G parts rather than the memory-limited 8500G
- Drops into any AM5 motherboard already sold for the Ryzen 7000/9000/8000G lineup
Cons
- No integrated graphics at all, so a discrete GPU is mandatory even for basic display output
- 16 MB of L3 cache is half that of the same-price-class Ryzen 5 7600, which can cost a few percent in cache-sensitive games
- PCIe 4.0 only, a step behind the PCIe 5.0 slot on non-G Ryzen 7000/9000 desktop chips
- Launched quietly months after the rest of the 8000G family with less independent review coverage, so verified benchmark data stays thinner
Awaiting benchmarks
No Inno Score yet: single-core still needs a published benchmark result.
