Quick Answers

So, is Ryzen 5 3600 better than Athlon II Neo K145?

Yes. Ryzen 5 3600 is the better all-around CPU here. It gives you a 1360.1% average FPS lead across 49 shared CPU game tests in our data, 3030.1% 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 5 3600 is the better pick. According to our tests, it delivers 1360.1% 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 5 3600 is the stronger fit. You are getting 3030.1% better PassMark, backed by 6 cores and 12 threads.

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

Ryzen 5 3600 is the better buy right now. Ryzen 5 3600 comes in 298.0% more expensive on MSRP at $199 MSRP versus $50 MSRP, and it still gives you a 1360.1% average FPS lead across 49 shared CPU game tests in our data. It is also 686.5% better value on MSRP (88.9 vs 11.3 PassMark/$), 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 5 3600 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2019 vs 2010) and more multi-core headroom with 6 cores / 12 threads instead of 1/1. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
