Quick Answers

So, is Celeron B830 better than Celeron 877?

Yes. Celeron B830 is the better all-around CPU here. It gives you 1.2% 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 B830 has the edge because it leads the single-thread side of this matchup with 28.6% higher max boost clock.

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

For streaming, content creation, and heavier multitasking, Celeron B830 is the stronger fit. You are getting 1.2% better PassMark, backed by 2 cores and 2 threads.

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

Celeron B830 is the easy recommendation for a fresh desktop build. Celeron B830 comes in at an unclear MSRP at unclear MSRP versus $86 MSRP, and it still gives you 1.2% higher PassMark. Celeron 877 only looks good on raw value math because it is a cheap legacy laptop chip, not because it is a real desktop gaming recommendation. It simply does not keep up in modern games.

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

Celeron B830 makes more sense long term for 2026 and beyond. You are getting 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.
