Quick Answers

So, is Celeron 1000M better than Celeron B840?

It depends on what you want from the system. For gaming, Celeron B840 is ahead with a 0.1% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Celeron 1000M pulls ahead with 0.5% better PassMark.

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

For streaming, content creation, and heavier multitasking, Celeron 1000M is the stronger fit. You are getting 0.5% better PassMark, backed by 2 cores and 2 threads.

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

Celeron 1000M is the better buy right now. Celeron 1000M comes in in basically the same MSRP band at $86 MSRP versus $86 MSRP, and it still gives you 0.5% better PassMark. The compromise is that Celeron B840 is still the better pure gaming CPU with a 0.1% average FPS lead across 50 shared CPU game tests in our data. It is also 0.5% better value on MSRP (12.4 vs 12.4 PassMark/$), 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 1000M 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 2/2. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
