Community Feedback

What Owners Say

Owners praise it for running cool and quiet in small builds. The usual gripe is that it feels weak for anything beyond basic office work or media streaming.

Pros

Sips power, stays whisper quiet
Handles daily tasks without breaking a sweat
Plays nice with stock coolers
Keeps office PCs frosty and stable

Cons

Only six cores in 2021
Integrated graphics are very weak
Limited PCIe 4.0 lanes

Verdict

Our verdict on the Core i5-11400T

An efficient low-power Rocket Lake chip for compact builds, held back by a higher price than its faster, cheaper predecessor.

Get it if you need a low-power chip for a tiny office PC or home server that stays cool without a loud fan. Skip it if you want to play modern games or edit video, because its six cores and lower speeds will hold you back.
