Gets you into modern games

Cons

Locked to non-overclockable chipset
No hyperthreading in 2019
Lacks integrated graphics for troubleshooting

Verdict

Our verdict on the Core i5-9400F

A mid-range Coffee Lake-R chip that skips integrated graphics to lower cost, decent for budget gaming builds.

Get it if you’re building a budget gaming PC and want solid performance without paying for integrated graphics you won’t use. Skip it if you need multithreading for video editing or streaming, as older Ryzen chips offer better value.
