Quick Answers

So, is Pentium M 730 better than Sempron 3400+?

It depends on what you want from the system. For gaming, Sempron 3400+ is ahead with 25% higher max boost clock. For rendering, compiling, streaming, and heavier multitasking, Pentium M 730 pulls ahead with 0.5% better PassMark.

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

For streaming, content creation, and heavier multitasking, Pentium M 730 is the stronger fit. You are getting 0.5% better PassMark, backed by 1 cores and 1 threads.

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

Pentium M 730 still makes the most sense overall. Pentium M 730 comes in at an unclear MSRP at unclear MSRP versus unclear MSRP, and it still gives you 0.5% better PassMark.

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

Pentium M 730 makes more sense long term for 2026 and beyond. You are getting 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.
