Quick Answers

So, is Xeon E-2478 better than EPYC 7401P?

It depends on what you want from the system. For gaming, Xeon E-2478 is ahead with a 2.3% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, EPYC 7401P pulls ahead with 0.2% better PassMark. EPYC 7401P also has the bigger cache pool with 166.7% larger total L3 cache (64 MB vs 24 MB).

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

For streaming, content creation, and heavier multitasking, EPYC 7401P is the stronger fit. You are getting 0.2% better PassMark, backed by 24 cores and 48 threads. It also has the larger cache pool with 166.7% larger total L3 cache (64 MB vs 24 MB).

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

Xeon E-2478 is the better buy right now. Xeon E-2478 comes in at an unclear MSRP at $568 MSRP versus unclear MSRP, and it still gives you a 2.3% average FPS lead across 50 shared CPU game tests in our data. The compromise is that EPYC 7401P is still stronger for heavier multi-core work with 0.2% better PassMark. It is also 100.0% better value on MSRP (48.9 vs 0.0 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.

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

Xeon E-2478 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2023 vs 2017) and a healthier platform with LGA1700 and DDR5 instead of TR4. That gives you a healthier platform runway for motherboard, RAM, and later CPU upgrades.
