What Owners Say
Owners like it for being a solid, affordable workhorse that handles gaming and multitasking without breaking a sweat. The usual gripe is that it’s locked, so you can’t overclock, and the stock cooler is pretty loud under load.
- Plays all modern games without stutter
- Handles heavy multitasking without breaking a sweat
- Runs cool and quiet even under load
- Works with affordable motherboards and memory
- Locked to non-overclockable motherboards
- Older architecture with no upgrade path
- Integrated graphics are very weak
Our verdict on the Core i5-10400
A competent six-core Comet Lake chip that arrived just late enough to feel dated against AMD's cheaper alternatives.
Get it if you need a solid, affordable CPU for a basic office PC or light gaming build that runs cool and quiet on a budget LGA1200 board. Skip it if you want modern performance for heavy multitasking or gaming—newer chips are faster and worth the extra cash.
Buy it if…
- You want a good budget gaming CPU for the price.
- You're building a dependable office or home PC.
- You need a solid upgrade for an older LGA1200 board.
