Quick Answers

So, is Celeron N4100 better than Phenom II X4 840?

It depends on what you want from the system. For gaming, Phenom II X4 840 is ahead with a 3.0% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Celeron N4100 pulls ahead with 0.2% better PassMark.

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

For streaming, content creation, and heavier multitasking, Celeron N4100 is the stronger fit. You are getting 0.2% better PassMark, backed by 4 cores and 4 threads.

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

Celeron N4100 still makes the most sense overall. Celeron N4100 comes in at an unclear MSRP at unclear MSRP versus unclear MSRP, and it still gives you 0.2% better PassMark.

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

Celeron N4100 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2017 vs 2011) and more multi-core headroom with 4 cores / 4 threads instead of 4/4. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
