Quick Answers

So, is Celeron J4025 better than A8-3520M?

Yes. Celeron J4025 is the better all-around CPU here. It gives you a 2.1% average FPS lead across 50 shared CPU game tests in our data, 0.6% 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 J4025 is the better pick. According to our tests, it delivers 2.1% 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 J4025 is the stronger fit. You are getting 0.6% better PassMark, backed by 2 cores and 2 threads.

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

Celeron J4025 still makes the most sense overall. Celeron J4025 comes in at an unclear MSRP at unclear MSRP versus unclear MSRP, and it still gives you a 2.1% average FPS lead across 50 shared CPU game tests in our data.

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

Celeron J4025 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2019 vs 2011) 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.
