Quick Answers

So, is Ryzen AI 9 HX 375 better than EPYC 4364P?

Not in a simple one-size-fits-all way. EPYC 4364P makes more sense for workstation-style multi-core throughput, while Ryzen AI 9 HX 375 is the better mainstream desktop choice for gaming, platform cost, and day-to-day practicality.

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

For streaming, content creation, and heavier multitasking, Ryzen AI 9 HX 375 is the better fit. You are getting 5.9% better Cinebench R23 multi-core, backed by 12 cores and 24 threads.

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

Ryzen AI 9 HX 375 is still the faster CPU overall, but EPYC 4364P makes more sense if price matters more than absolute performance. Ryzen AI 9 HX 375 is at an unclear MSRP at unclear MSRP versus $399 MSRP, and it gives you 5.9% better Cinebench R23 multi-core. The trade-off is that EPYC 4364P is still the better pure gaming CPU with a 33.7% average FPS lead across 50 shared CPU game tests in our data. EPYC 4364P is also 100.0% better value on MSRP (85.8 vs 0.0 PassMark/$), 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 AI 9 HX 375 is the more future-proof choice for 2026 and beyond. You are getting more multi-core headroom with 12 cores / 24 threads instead of 8/16. That extra compute headroom should age better as games, background tasks, and creator workloads get heavier.
