Quick Answers

So, is Pentium 3805U better than Celeron N2806?

It depends on what you want from the system. For gaming, Celeron N2806 is ahead with a 1.7% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Pentium 3805U pulls ahead with 0.1% better PassMark.

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

For streaming, content creation, and heavier multitasking, Pentium 3805U 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?

Pentium 3805U still makes the most sense overall. Pentium 3805U comes in at an unclear MSRP at unclear MSRP versus unclear MSRP, and it still gives you 0.1% better PassMark.

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

Pentium 3805U makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2015 vs 2013) 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.
