Quick Answers

So, is Ryzen 7 5800X better than Xeon D-2146NT?

Not really, because they are built for different jobs. Xeon D-2146NT makes more sense for workstation-style multi-core throughput, while Ryzen 7 5800X is the more practical desktop choice for gaming, platform cost, and everyday use.

Which one is better for gaming?

If gaming is the priority, Ryzen 7 5800X is the better pick. According to our tests, it delivers 51.1% 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 136.1% better PassMark, backed by 8 cores and 16 threads. It also has the larger cache pool with 190.9% larger total L3 cache (32 MB vs 11 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 $449 MSRP versus unclear MSRP, and it still gives you a 51.1% average FPS lead across 50 shared CPU game tests in our data. It is also 100.0% better value on MSRP (61.7 vs 0.0 PassMark/$), 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 2018), 190.9% larger total L3 cache (32 MB vs 11 MB), and more multi-core headroom with 8 cores / 16 threads instead of 8/16. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
