Quick Answers

So, is Ryzen 9 5900X better than Sempron 2400+?

Yes. Ryzen 9 5900X is the better all-around CPU here. It gives you a 3734.1% average FPS lead across 49 shared CPU game tests in our data, 14768.3% 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, Ryzen 9 5900X is the better pick. According to our tests, it delivers 3734.1% 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, Ryzen 9 5900X is the stronger fit. You are getting 14768.3% better PassMark, backed by 12 cores and 24 threads.

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

Ryzen 9 5900X is the better buy right now. Ryzen 9 5900X comes in at an unclear MSRP at $549 MSRP versus unclear MSRP, and it still gives you a 3734.1% average FPS lead across 49 shared CPU game tests in our data. It is also 100.0% better value on MSRP (71.0 vs 0.0 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.

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

Ryzen 9 5900X makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2020 vs 2001) and more multi-core headroom with 12 cores / 24 threads instead of 1/1. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
