Quick Answers

So, is Ryzen 5 5600X better than Ryzen 5 3450U?
Yes. Ryzen 5 5600X is the better overall CPU here. You are getting a 81.2% average FPS lead across 50 shared CPU game tests in our data, 233.5% better PassMark, and the stronger long-term platform, which makes it the stronger all-around choice.
Which one is better for gaming?
If gaming is the priority, Ryzen 5 5600X is the better pick here. According to our tests, it delivers 81.2% 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 5 5600X is the better fit. You are getting 233.5% better PassMark, backed by 6 cores and 12 threads. It also carries the larger cache pool with 700% larger total L3 cache (32 MB vs 4 MB).
Which one is the smarter buy today, not just the cheaper CPU?
Ryzen 5 5600X is the smarter buy today. Ryzen 5 5600X is at an unclear MSRP at $299 MSRP versus unclear MSRP, and it gives you a 81.2% average FPS lead across 50 shared CPU game tests in our data. It is also 100.0% better value on MSRP (73.1 vs 0.0 PassMark/$), so the better CPU is not just faster, it is also the cleaner value play on paper.
Which one is more future-proof for 2026 and beyond?
Ryzen 5 5600X is the more future-proof choice for 2026 and beyond. You are getting 700% larger total L3 cache (32 MB vs 4 MB) and more multi-core headroom with 6 cores / 12 threads instead of 4/8. That extra compute headroom should age better as games, background tasks, and creator workloads get heavier.

Games Benchmarks

Paired with RTX 4090

To accurately isolate CPU performance, all benchmarks below use an NVIDIA RTX 4090 as the reference GPU. This eliminates GPU-side bottlenecks and highlights pure processing throughput differences between the CPUs.

Note: Real-world results may vary based on your actual GPU. CPU performance impact is more visible in processing-intensive titles and high-refresh-rate gaming scenarios.
