Quick Answers

So, is Celeron 450 better than Pentium M 750?

Yes. Celeron 450 is the better all-around CPU here. It gives you 2.1% 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, Celeron 450 has the edge because it leads the single-thread side of this matchup with 18.3% higher max boost clock.

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

For streaming, content creation, and heavier multitasking, Celeron 450 is the stronger fit. You are getting 2.1% better PassMark, backed by 1 cores and 1 threads.

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

Celeron 450 is the better buy right now. Celeron 450 comes in at an unclear MSRP at $53 MSRP versus unclear MSRP, and it still gives you 2.1% higher PassMark. It is also 100.0% better value on MSRP (9.3 vs 0.0 PassMark/$), 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 450 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2008 vs 2005) and more multi-core headroom with 1 cores / 1 threads instead of 1/1. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
