Quick Answers

So, is Celeron 4305UE better than Core i3-3120M?
Yes. Celeron 4305UE is the better all-around CPU here. It gives you a 2.8% average FPS lead across 50 shared CPU game tests in our data, 14.5% better Geekbench multi-core, and the stronger long-term platform, which is enough to make it the stronger overall pick.
Which one is better for gaming?
If gaming is the priority, Celeron 4305UE is the better pick. According to our tests, it delivers 2.8% more average FPS across 50 shared CPU game tests.
Which one is better for streaming, content creation, and heavy multitasking?
For streaming, content creation, and heavier multitasking, Celeron 4305UE is the stronger fit. You are getting 14.5% better Geekbench multi-core, backed by 2 cores and 2 threads.
Which one is the smarter buy today, not just the cheaper CPU?
Celeron 4305UE is the better buy right now. Celeron 4305UE comes in at an unclear MSRP at $107 MSRP versus unclear MSRP, and it still gives you a 2.8% average FPS lead across 50 shared CPU game tests in our data. It is also 100.0% better value on MSRP (15.9 vs 0.0 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.
Which one is more future-proof for 2026 and beyond?
Celeron 4305UE makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2018 vs 2012) and more multi-core headroom with 2 cores / 2 threads instead of 2/4. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
