Community Feedback

What Owners Say

Owners like it for basic office work and media servers because it sips power and runs cool. The usual gripe is it chokes on anything beyond light multitasking or web browsing.

Pros

Sips power, stays whisper quiet
Handles basic desktop tasks fine
Runs cool without a big fan
Ships in cheap, tiny systems

Cons

Only two physical cores
No hyperthreading support at all
Integrated graphics are very weak

Verdict

Our verdict on the Celeron J4005

A low-power, dual-core chip from 2017 that's really only useful for basic office work or as a home server.

Get it if you're building a dirt-cheap office PC or a low-power home server that just needs to browse the web and play video. Skip it if you plan to do any multitasking, gaming, or modern work—it's too slow for anything beyond basic tasks.
