Quick Answers

So, is Celeron 450 better than Mobile Pentium 4 3.06?

It depends on what you want from the system. For gaming, Mobile Pentium 4 3.06 is ahead with a 0.2% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Celeron 450 pulls ahead with 4.2% better PassMark.

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 4.2% 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 $53 MSRP versus unclear MSRP, and it still gives you 4.2% better PassMark. The compromise is that Mobile Pentium 4 3.06 is still the better pure gaming CPU with a 0.2% average FPS lead across 50 shared CPU game tests in our data. It is also 100.0% better value on MSRP (9.3 vs 0.0 PassMark/$), 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 2003) and more multi-core headroom with 1 cores / 1 threads instead of 1/2. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
