If gaming is the priority, Ryzen 7 5800X is the better pick. According to our tests, it delivers 100.2% 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 7 5800X is the stronger fit. You are getting 388.7% better PassMark, backed by 8 cores and 16 threads. It also has the larger cache pool with 166.7% larger total L3 cache (32 MB vs 12 MB).

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

Ryzen 7 5800X is the better buy right now. Ryzen 7 5800X comes in at an unclear MSRP at $449 MSRP versus unclear MSRP, and it still gives you a 100.2% average FPS lead across 50 shared CPU game tests in our data. It is also 100.0% better value on MSRP (61.7 vs 0.0 PassMark/$), 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 7 5800X makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2020 vs 2017), 166.7% larger total L3 cache (32 MB vs 12 MB), and more multi-core headroom with 8 cores / 16 threads instead of 12/12. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
