Quick Answers

So, is Athlon 64 3100+ better than Pentium M 750?

It depends on what you want from the system. For gaming, Athlon 64 3100+ 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, Pentium M 750 pulls ahead with 2.1% better PassMark.

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

For streaming, content creation, and heavier multitasking, Pentium M 750 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?

Athlon 64 3100+ is the better buy right now. Athlon 64 3100+ comes in at an unclear MSRP at $100 MSRP versus unclear MSRP, and it still gives you a 0.2% average FPS lead across 50 shared CPU game tests in our data. The compromise is that Pentium M 750 is still stronger for heavier multi-core work with 2.1% better PassMark. It is also 100.0% better value on MSRP (4.8 vs 0.0 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.

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

Athlon 64 3100+ makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2008 vs 2005). That makes it the safer long-term bet.
