Quick Answers

So, is EPYC 4464P better than Xeon w5-2555X?

It depends on what you want from the system. For gaming, EPYC 4464P is ahead with a 2.7% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Xeon w5-2555X pulls ahead with 1% better PassMark.

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

For streaming, content creation, and heavier multitasking, Xeon w5-2555X is the stronger fit. You are getting 1% better PassMark, backed by 14 cores and 28 threads.

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

EPYC 4464P is the better buy right now. EPYC 4464P comes in $640 cheaper on MSRP at $429 MSRP versus $1,069 MSRP, and it still gives you a 2.7% average FPS lead across 50 shared CPU game tests in our data. The compromise is that Xeon w5-2555X is still stronger for heavier multi-core work with 1% better PassMark. It is also 146.8% better value on MSRP (110.0 vs 44.6 PassMark/$), 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 w5-2555X makes more sense long term for 2026 and beyond. You are getting more multi-core headroom with 14 cores / 28 threads instead of 12/24. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
