Quick Answers

So, is Celeron G3900T better than Core M-5Y70?

Yes. Celeron G3900T is the better all-around CPU here. It gives you a 2.8% average FPS lead across 44 shared CPU game tests in our data, 0.5% better PassMark, and the stronger long-term platform, which is enough to make it the stronger overall pick.

Which one is better for gaming?

For gaming, this matchup is basically a tie in the data we have.

Which one is better for streaming, content creation, and heavy multitasking?

For streaming, content creation, and heavier multitasking, Celeron G3900T is the stronger fit. You are getting 0.5% better PassMark, backed by 2 cores and 2 threads.

Which one is the smarter buy today, not just the cheaper CPU?

Celeron G3900T is the better buy right now. Celeron G3900T comes in $239 cheaper on MSRP at $42 MSRP versus $281 MSRP, and it still gives you a 2.8% average FPS lead across 44 shared CPU game tests in our data. It is also 572.6% better value on MSRP (45.2 vs 6.7 PassMark/$), 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 G3900T makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2015 vs 2014) 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.
