Quick Answers

So, is Pentium III 1400S better than Pentium 4 1.80?

It depends on what you want from the system. For gaming, Pentium 4 1.80 is ahead with 28.6% higher max boost clock. For rendering, compiling, streaming, and heavier multitasking, Pentium III 1400S pulls ahead with 1.3% better PassMark.

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

For streaming, content creation, and heavier multitasking, Pentium III 1400S is the stronger fit. You are getting 1.3% better PassMark, backed by 1 cores and 1 threads.

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

Pentium III 1400S is the better buy right now. Pentium III 1400S comes in $312 cheaper on MSRP at $250 MSRP versus $562 MSRP, and it still gives you 1.3% better PassMark. The compromise is that Pentium 4 1.80 is still the better pure gaming CPU with 28.6% higher max boost clock. It is also 127.8% better value on MSRP (0.9 vs 0.4 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.

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

Pentium III 1400S makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2002 vs 2001) 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.
