Quick Answers

So, is Ryzen 9 5900X better than Pentium Dual Core T2390?
Yes. Ryzen 9 5900X is the better all-around CPU here. It gives you a 595.0% average FPS lead across 34 shared CPU game tests in our data, 2099.6% better PassMark, and the stronger long-term platform, which is enough to make it the stronger overall pick.
Which one is better for gaming?
If gaming is the priority, Ryzen 9 5900X is the better pick. According to our tests, it delivers 595.0% more average FPS across 34 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 2099.6% 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 538.4% more expensive on MSRP at $549 MSRP versus $86 MSRP, and it still gives you a 595.0% average FPS lead across 34 shared CPU game tests in our data. It is also 244.6% better value on MSRP (71.0 vs 20.6 PassMark/$), 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 2008) and more multi-core headroom with 12 cores / 24 threads instead of 2/2. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
