Quick Answers

So, is Celeron 3867U better than Core i3-4020Y?

Yes. Celeron 3867U is the better all-around CPU here. It gives you 0.1% better PassMark 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 3867U has the edge because it leads the single-thread side of this matchup with 20% higher max boost clock.

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

For streaming, content creation, and heavier multitasking, Celeron 3867U is the stronger fit. You are getting 0.1% better PassMark, backed by 2 cores and 2 threads.

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

Celeron 3867U still makes the most sense overall. Celeron 3867U comes in at an unclear MSRP at unclear MSRP versus unclear MSRP, and it still gives you 0.1% higher PassMark.

Which one is more future-proof for 2026 and beyond?

Celeron 3867U makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2019 vs 2013) 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.
