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

EPYC 4364P is the smarter buy today. EPYC 4364P is at an unclear MSRP at $399 MSRP versus unclear MSRP, and it gives you a 22.8% average FPS lead across 33 shared CPU game tests in our data. The trade-off is that Ryzen 9 PRO 5945 is still stronger for heavier multi-core work with 10.5% better Cinebench R23 multi-core. It is also 100.0% better value on MSRP (85.8 vs 0.0 PassMark/$), 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?

EPYC 4364P is the more future-proof choice for 2026 and beyond. You are getting a newer CPU generation (2024 vs 2022), a healthier platform with AM5 and DDR5 instead of AM4, and AVX-512 support for heavier modern compute workloads. That should give you a better long-term upgrade path for motherboard, RAM, and future CPU swaps.
