Community Feedback

What Owners Say

Folks praise it as a dirt-cheap basic office chip that sips power. The main gripe is it feels painfully slow with just two cores for anything beyond typing.

Pros

Perfect for a basic office PC
Runs cool with the stock cooler
Handles light web browsing just fine
Uses very little electricity

Cons

Two cores for modern multitasking
Integrated graphics are very weak
No hyper-threading hurts performance

Verdict

Our verdict on the Celeron G5900

A Comet Lake dual-core chip with no multithreading that’s fine for basic office work but chokes on any serious multitasking.

Get it if you're building a dirt-cheap office PC or a basic home server that just needs to run Windows and browse the web. Skip it if you plan to multitask, game, or do anything more demanding than opening a single application at a time.
