Community Feedback
What Owners Say
Owners like it for being a solid, no-drama performer for everyday tasks and light gaming. The usual gripe is that it feels dated now and struggles with newer, heavier workloads.
Pros
- Gets everyday work done without fuss
- Runs cool in a compact PC
- Plays older games at decent settings
- Sips power for a quiet build
Cons
- Feels slow in modern games
- Only four cores, no hyperthreading
- Locked multiplier limits overclocking
Verdict
Our verdict on the Core i5-7400
A Kaby Lake quad-core CPU with built-in graphics that was fine in 2017 but aged poorly against cheaper, faster alternatives.
Get it if you need a cheap, basic office PC upgrade that works out of the box with older motherboards. Skip it if you want any modern gaming or multitasking performance, as even budget chips today run circles around it.
Buy it if…
- You want a cheap office PC for basic web browsing and documents.
- You need a simple upgrade from a very old Sandy Bridge system.
- You're building a low-budget gaming PC with a GTX 1050 or RX 560.
