Quick Answers

So, is Xeon W-2265 better than EPYC 7551?

It depends on what you want from the system. For gaming, Xeon W-2265 is ahead with a 14.6% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, EPYC 7551 pulls ahead with 0.6% better PassMark. EPYC 7551 also has the bigger cache pool with 232.5% larger total L3 cache (64 MB vs 19 MB).

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

For streaming, content creation, and heavier multitasking, EPYC 7551 is the stronger fit. You are getting 0.6% better PassMark, backed by 32 cores and 64 threads. It also has the larger cache pool with 232.5% larger total L3 cache (64 MB vs 19 MB).

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

Xeon W-2265 is the better buy right now. Xeon W-2265 comes in at an unclear MSRP at $1,039 MSRP versus unclear MSRP, and it still gives you a 14.6% average FPS lead across 50 shared CPU game tests in our data. The compromise is that EPYC 7551 is still stronger for heavier multi-core work with 0.6% better PassMark. It is also 100.0% better value on MSRP (24.7 vs 0.0 PassMark/$), 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 W-2265 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2019 vs 2017). That makes it the safer long-term bet.
