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

Ryzen 9 7945HX3D is still the faster CPU overall, but Ryzen 5 5600 makes more sense if price matters more than absolute performance. Ryzen 9 7945HX3D is at an unclear MSRP at unclear MSRP versus $199 MSRP, and it gives you a 59.4% average FPS lead across 4 shared CPU game tests in our data. Ryzen 5 5600 is also 100.0% better value on MSRP (108.3 vs 0.0 PassMark/$), 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 7945HX3D is the more future-proof choice for 2026 and beyond. You are getting a newer CPU generation (2023 vs 2022), a healthier platform with FL1 and DDR5 instead of AM4, 3D V-Cache and a much larger 128 MB L3 cache instead of 32 MB, and more multi-core headroom with 16 cores / 32 threads instead of 6/12. That should give you a better long-term upgrade path for motherboard, RAM, and future CPU swaps.

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.
