Quick Answers

So, is EPYC 9355P better than Xeon 6747P?

It depends on what you want from the system. For gaming, EPYC 9355P is ahead with a 13.2% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Xeon 6747P pulls ahead with 4.6% better PassMark.

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

For streaming, content creation, and heavier multitasking, Xeon 6747P is the stronger fit. You are getting 4.6% better PassMark, backed by 48 cores and 96 threads.

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

EPYC 9355P is the better buy right now. EPYC 9355P comes in $3,499 cheaper on MSRP at $2,998 MSRP versus $6,497 MSRP, and it still gives you a 13.2% average FPS lead across 50 shared CPU game tests in our data. The compromise is that Xeon 6747P is still stronger for heavier multi-core work with 4.6% better PassMark. It is also 107.3% better value on MSRP (32.4 vs 15.7 PassMark/$), 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 6747P makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2025 vs 2024), more multi-core headroom with 48 cores / 96 threads instead of 32/64, and AVX-512 support for heavier modern compute workloads. That extra cache should keep paying off in CPU-limited games and high-refresh builds.
