Quick Answers

So, is A8-3800 better than Celeron 2955U?

It depends on what you want from the system. For gaming, A8-3800 is ahead with a 1.0% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Celeron 2955U pulls ahead with 0.9% better PassMark.

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

For streaming, content creation, and heavier multitasking, Celeron 2955U is the stronger fit. You are getting 0.9% better PassMark, backed by 2 cores and 2 threads.

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

A8-3800 is the better buy right now. A8-3800 comes in at an unclear MSRP at $130 MSRP versus unclear MSRP, and it still gives you a 1.0% average FPS lead across 50 shared CPU game tests in our data. The compromise is that Celeron 2955U is still stronger for heavier multi-core work with 0.9% better PassMark. It is also 100.0% better value on MSRP (15.8 vs 0.0 PassMark/$), 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 2955U makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2013 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.
