Quick Answers

So, is Ryzen 5 5600X better than Celeron 420?
Yes. Ryzen 5 5600X is the better all-around CPU here. It gives you a 1766.4% average FPS lead across 50 shared CPU game tests in our data, 5040% 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 5600X is the better pick. According to our tests, it delivers 1766.4% 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 5600X is the stronger fit. You are getting 5040% better PassMark, backed by 6 cores and 12 threads.
Which one is the smarter buy today, not just the cheaper CPU?
Ryzen 5 5600X is the better buy right now. Ryzen 5 5600X comes in 666.7% more expensive on MSRP at $299 MSRP versus $39 MSRP, and it still gives you a 1766.4% average FPS lead across 50 shared CPU game tests in our data. It is also 570.4% better value on MSRP (73.1 vs 10.9 PassMark/$), 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 5600X makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2020 vs 2007) 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.
