Quick Answers

So, is Pentium G840 better than Pentium G630?

Yes. Pentium G840 is the better all-around CPU here. It gives you 1% 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, Pentium G840 has the edge because it leads the single-thread side of this matchup with 3.7% higher max boost clock.

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

For streaming, content creation, and heavier multitasking, Pentium G840 is the stronger fit. You are getting 1% better PassMark, backed by 2 cores and 2 threads.

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

Pentium G840 is the better buy right now. Pentium G840 comes in $11 cheaper on MSRP at $64 MSRP versus $75 MSRP, and it still gives you 1.0% higher PassMark. It is also 18.3% better value on MSRP (21.4 vs 18.1 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.

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

Pentium G840 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.
