Quick Answers

So, is Celeron 3965U better than Athlon X2 L310?

Yes. Celeron 3965U is the better all-around CPU here. It gives you a 1.8% average FPS lead across 50 shared CPU game tests in our data, 463.4% better Geekbench multi-core, 0.3% higher 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 3965U is the better pick. According to our tests, it delivers 1.8% 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 3965U is the stronger fit. You are getting 463.4% better Geekbench multi-core, backed by 2 cores and 2 threads.

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

Celeron 3965U is still the much better call for a fresh build. Celeron 3965U comes in at an unclear MSRP at unclear MSRP versus $100 MSRP, and it still gives you a 1.8% average FPS lead across 50 shared CPU game tests in our data. Athlon X2 L310 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2009 platform. Even with 100.0% better value on paper (17.5 vs 0.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on S1.

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

Celeron 3965U makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2017 vs 2009) and more multi-core headroom with 2 cores / 2 threads instead of 2/2. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
