Quick Answers

So, is Celeron G3900 better than A10-7400P?

It depends on what you want from the system. For gaming, A10-7400P is ahead with a 1.1% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Celeron G3900 pulls ahead with 1% better PassMark.

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

For streaming, content creation, and heavier multitasking, Celeron G3900 is the stronger fit. You are getting 1% better PassMark, backed by 2 cores and 2 threads.

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

Celeron G3900 is the better buy right now. Celeron G3900 comes in at an unclear MSRP at $42 MSRP versus unclear MSRP, and it still gives you 1% better PassMark. The compromise is that A10-7400P is still the better pure gaming CPU with a 1.1% average FPS lead across 50 shared CPU game tests in our data. It is also 100.0% better value on MSRP (51.3 vs 0.0 PassMark/$), 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 G3900 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 4/4. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
