Quick Answers

So, is Ryzen 5 5600 better than Xeon E5420?

Not really, because they are built for different jobs. Xeon E5420 makes more sense for workstation-style multi-core throughput, while Ryzen 5 5600 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 5 5600 is the better pick. According to our tests, it delivers 338.9% 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 876.2% better Geekbench multi-core, backed by 6 cores and 12 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 5 5600 is the better buy right now. Ryzen 5 5600 comes in $7,015 cheaper on MSRP at $199 MSRP versus $7,214 MSRP, and it still gives you a 338.9% average FPS lead across 50 shared CPU game tests in our data. It is also 38119.9% better value on MSRP (108.3 vs 0.3 PassMark/$), 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 5600 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2022 vs 2007), 166.7% larger total L3 cache (32 MB vs 12 MB), and more multi-core headroom with 6 cores / 12 threads instead of 4/4. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
