Quick Answers

So, is Xeon 6781P better than EPYC 9745?

It depends on what you want from the system. For gaming, Xeon 6781P is ahead with a 2.9% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, EPYC 9745 pulls ahead with 10.8% 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, EPYC 9745 is the stronger fit. You are getting 10.8% better PassMark, backed by 128 cores and 256 threads.

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

Xeon 6781P is the better buy right now. Xeon 6781P comes in $3,181 cheaper on MSRP at $8,960 MSRP versus $12,141 MSRP, and it still gives you a 2.9% average FPS lead across 50 shared CPU game tests in our data. The compromise is that EPYC 9745 is still stronger for heavier multi-core work with 10.8% better PassMark. It is also 22.3% better value on MSRP (13.2 vs 10.8 PassMark/$), 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) and 31.3% larger total L3 cache (336 MB vs 256 MB). That extra cache should keep paying off in CPU-limited games and high-refresh builds.
