Quick Answers

So, is Pentium M 1.50 better than Sempron 3100+?

It depends on what you want from the system. For gaming, Sempron 3100+ is ahead with 20% higher max boost clock. For rendering, compiling, streaming, and heavier multitasking, Pentium M 1.50 pulls ahead with 0.8% better PassMark.

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

For streaming, content creation, and heavier multitasking, Pentium M 1.50 is the stronger fit. You are getting 0.8% better PassMark, backed by 1 cores and 1 threads.

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

Pentium M 1.50 is still the much better call for a fresh build. Pentium M 1.50 comes in at an unclear MSRP at unclear MSRP versus $65 MSRP, and it still gives you 0.8% better PassMark. Sempron 3100+ only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2001 platform. Even with 100.0% better value on paper (5.7 vs 0.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on 754.

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

Pentium M 1.50 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2003 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.
