Quick Answers

So, is Ryzen 9 PRO 5945 better than Ryzen 5 5600X?

Yes. Ryzen 9 PRO 5945 is the better overall CPU here. You are getting a 31.7% average FPS lead across 4 shared CPU game tests in our data, 58.2% 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 9 PRO 5945 is the better pick here. According to our tests, it delivers 31.7% more average FPS across 4 shared CPU game tests.

Which one is better for streaming, content creation, and heavy multitasking?

For streaming, content creation, and heavier multitasking, Ryzen 9 PRO 5945 is the better fit. You are getting 58.2% better PassMark, backed by 12 cores and 24 threads. It also carries the larger cache pool with 100% larger total L3 cache (64 MB vs 32 MB).

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

Ryzen 9 PRO 5945 is still the faster CPU overall, but Ryzen 5 5600X makes more sense if price matters more than absolute performance. Ryzen 9 PRO 5945 is at an unclear MSRP at unclear MSRP versus $299 MSRP, and it gives you a 31.7% average FPS lead across 4 shared CPU game tests in our data. Ryzen 5 5600X is also 100.0% better value on MSRP (73.1 vs 0.0 PassMark/$), which is why it is easier to justify for price-conscious builds on paper.

Which one is more future-proof for 2026 and beyond?

Ryzen 9 PRO 5945 is the more future-proof choice for 2026 and beyond. You are getting a newer CPU generation (2022 vs 2020), 100% larger total L3 cache (64 MB vs 32 MB), and more multi-core headroom with 12 cores / 24 threads instead of 6/12. 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.
