Quick Answers

So, is Athlon 64 3100+ better than Pentium M 745?

Yes. Athlon 64 3100+ is the better all-around CPU here. It gives you a 0.2% average FPS lead across 50 shared CPU game tests in our data, 180% better Geekbench multi-core, 2.2% higher 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, Athlon 64 3100+ is the better pick. According to our tests, it delivers 0.2% more average FPS across 50 shared CPU game tests.

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

For streaming, content creation, and heavier multitasking, Athlon 64 3100+ is the stronger fit. You are getting 180% better Geekbench multi-core, 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 $100 MSRP versus unclear MSRP, and it still gives you a 0.2% average FPS lead across 50 shared CPU game tests in our data. It is also 100.0% better value on MSRP (4.8 vs 0.0 PassMark/$), 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 2004) 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.
