Quick Answers

So, is EPYC 9455P better than Xeon 6781P?

It depends on what you want from the system. For gaming, EPYC 9455P is ahead with a 14.4% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Xeon 6781P pulls ahead with 0.9% better PassMark. Xeon 6781P also has the bigger cache pool with 31.3% larger total L3 cache (336 MB vs 256 MB).

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

For streaming, content creation, and heavier multitasking, Xeon 6781P is the stronger fit. You are getting 0.9% better PassMark, backed by 80 cores and 160 threads. It also has the larger cache pool with 31.3% larger total L3 cache (336 MB vs 256 MB).

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

EPYC 9455P is the better buy right now. EPYC 9455P comes in $4,141 cheaper on MSRP at $4,819 MSRP versus $8,960 MSRP, and it still gives you a 14.4% average FPS lead across 50 shared CPU game tests in our data. The compromise is that Xeon 6781P is still stronger for heavier multi-core work with 0.9% better PassMark. It is also 84.3% better value on MSRP (24.3 vs 13.2 PassMark/$), 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 6781P makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2025 vs 2024), 31.3% larger total L3 cache (336 MB vs 256 MB), and more multi-core headroom with 80 cores / 160 threads instead of 48/96. That extra cache should keep paying off in CPU-limited games and high-refresh builds.
