Quick Answers

So, is EPYC 9354 better than Xeon Gold 6448H?

Yes. EPYC 9354 is the better all-around CPU here. It gives you a 1.4% average FPS lead across 50 shared CPU game tests in our data, 5.1% better PassMark, and the stronger long-term platform, which is enough to make it the stronger overall pick.

Which one is better for gaming?

If gaming is the priority, EPYC 9354 is the better pick. According to our tests, it delivers 1.4% more average FPS across 50 shared CPU game tests. It also has a clear cache advantage at 256 MB versus 60 MB.

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

For streaming, content creation, and heavier multitasking, EPYC 9354 is the stronger fit. You are getting 5.1% better PassMark, backed by 32 cores and 64 threads. It also has the larger cache pool with 326.7% larger total L3 cache (256 MB vs 60 MB).

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

EPYC 9354 is the better buy right now. EPYC 9354 comes in $238 cheaper on MSRP at $3,420 MSRP versus $3,658 MSRP, and it still gives you a 1.4% average FPS lead across 50 shared CPU game tests in our data. It is also 12.4% better value on MSRP (21.6 vs 19.2 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.

Which one is more future-proof for 2026 and beyond?

EPYC 9354 makes more sense long term for 2026 and beyond. You are getting 3D V-Cache and a much larger 256 MB L3 cache instead of 60 MB and more multi-core headroom with 32 cores / 64 threads instead of 32/64. That extra cache should keep paying off in CPU-limited games and high-refresh builds.
