Quick Answers

So, is EPYC 4545P better than EPYC 7401?

It depends on what you want from the system. For gaming, EPYC 4545P is ahead with a 23.9% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, EPYC 7401 pulls ahead with 1.9% better PassMark.

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

For streaming, content creation, and heavier multitasking, EPYC 7401 is the stronger fit. You are getting 1.9% better PassMark, backed by 24 cores and 48 threads.

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

EPYC 4545P is the better buy right now. EPYC 4545P comes in $951 cheaper on MSRP at $549 MSRP versus $1,500 MSRP, and it still gives you a 23.9% average FPS lead across 50 shared CPU game tests in our data. The compromise is that EPYC 7401 is still stronger for heavier multi-core work with 1.9% better PassMark. It is also 168.2% better value on MSRP (98.8 vs 36.9 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.

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

EPYC 4545P makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2025 vs 2017), a healthier platform with AM5 and DDR5 instead of TR4, and AVX-512 support for heavier modern compute workloads. That gives you a healthier platform runway for motherboard, RAM, and later CPU upgrades.
