Quick Answers

So, is Mobile Sempron SI-40 better than Athlon MP 2400+?

Yes. Mobile Sempron SI-40 is the better all-around CPU here. It gives you 5.6% better PassMark and the stronger long-term platform, which is enough to make it the stronger overall pick.

Which one is better for gaming?

For gaming, this matchup is basically a tie in the data we have.

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

For streaming, content creation, and heavier multitasking, Mobile Sempron SI-40 is the stronger fit. You are getting 5.6% better PassMark, backed by 1 cores and 1 threads.

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

Mobile Sempron SI-40 is still the much better call for a fresh build. Mobile Sempron SI-40 comes in at an unclear MSRP at unclear MSRP versus $151 MSRP, and it still gives you 5.6% higher PassMark. Athlon MP 2400+ only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2002 platform. Even with 100.0% better value on paper (2.0 vs 0.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on that older platform.

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

Mobile Sempron SI-40 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2008 vs 2002) 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.
