Quick Answers

So, is Ryzen 5 5600 better than Pentium D 915?

Yes. Ryzen 5 5600 is the better all-around CPU here. It gives you a 1092.0% average FPS lead across 50 shared CPU game tests in our data, 2956.7% 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 5600 is the better pick. According to our tests, it delivers 1092.0% more average FPS across 50 shared CPU game tests.

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

For streaming, content creation, and heavier multitasking, Ryzen 5 5600 is the stronger fit. You are getting 2956.7% better PassMark, backed by 6 cores and 12 threads.

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

Ryzen 5 5600 is the better buy right now. Ryzen 5 5600 comes in 168.9% more expensive on MSRP at $199 MSRP versus $74 MSRP, and it still gives you a 1092.0% average FPS lead across 50 shared CPU game tests in our data. It is also 1036.7% better value on MSRP (108.3 vs 9.5 PassMark/$), 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 5600 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2022 vs 2006) and more multi-core headroom with 6 cores / 12 threads instead of 2/2. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
