Integrated graphics is very weak

Verdict

Our verdict on the Pentium Gold G6405

An aging dual-core desktop chip whose only real trick is running basic office tasks without breaking a sweat.

Get it if you need the cheapest possible chip for a basic office PC or home server that sips power. Skip it if you want to game, edit video, or do anything beyond web browsing and spreadsheets.
