Community Feedback
What Owners Say
Owners love the great bang for the buck in budget builds, but they gripe about being stuck on an older motherboard platform with no upgrade path.
Pros
- Crushes older Intel quad-cores in games
- Handles everyday multitasking without breaking a sweat
- Stays cool even with a budget cooler
- Won't bottleneck midrange graphics cards
Cons
- Locked to non-overclockable motherboards
- Limited to DDR4-2666 memory speed
- No integrated graphics for troubleshooting
Verdict
Our verdict on the Core i5-10400F
A six-core, twelve-thread Comet Lake chip that runs cool and cheap, but feels dated without PCIe 4.0.
Get it if you want a cheap, solid gaming CPU for a budget LGA1200 build that won't need heavy multitasking. Skip it if you need modern features like PCIe 4.0 or plan to run demanding creative software that uses lots of cores.
Buy it if…
- You need a cheap upgrade for an older LGA1200 board.
- You want solid gaming performance without paying for integrated graphics.
- You are building a budget office PC that won't break your desk.
