Quick Answers

So, is Sempron 2400+ better than Athlon XP 1800+?

Yes. Sempron 2400+ is the better all-around CPU here. It gives you a 16.7% average FPS lead across 49 shared CPU game tests in our data, 16.4% better 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, Sempron 2400+ is the better pick. According to our tests, it delivers 16.7% more average FPS across 49 shared CPU game tests.

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

For streaming, content creation, and heavier multitasking, Sempron 2400+ is the stronger fit. You are getting 16.4% better PassMark, backed by 1 cores and 1 threads.

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

Sempron 2400+ is still the much better call for a fresh build. Sempron 2400+ comes in at an unclear MSRP at unclear MSRP versus $252 MSRP, and it still gives you a 16.7% average FPS lead across 49 shared CPU game tests in our data. Athlon XP 1800+ only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2001 platform. Even with 100.0% better value on paper (0.9 vs 0.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on A.

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

Sempron 2400+ 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.
