Quick Answers

So, is EPYC 7313 better than EPYC 7551P?

Yes. EPYC 7313 is the better all-around CPU here. It gives you a 0.1% average FPS lead across 50 shared CPU game tests in our data, 2.2% 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 7313 is the better pick. According to our tests, it delivers 0.1% more average FPS across 50 shared CPU game tests. It also has a clear cache advantage at 128 MB versus 64 MB.

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

For streaming, content creation, and heavier multitasking, EPYC 7313 is the stronger fit. You are getting 2.2% better PassMark, backed by 16 cores and 32 threads. It also has the larger cache pool with 100% larger total L3 cache (128 MB vs 64 MB).

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

EPYC 7313 is the better buy right now. EPYC 7313 comes in $1,017 cheaper on MSRP at $1,083 MSRP versus $2,100 MSRP, and it still gives you a 0.1% average FPS lead across 50 shared CPU game tests in our data. It is also 98.1% better value on MSRP (36.0 vs 18.1 PassMark/$), 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 7313 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2021 vs 2017), 3D V-Cache and a much larger 128 MB L3 cache instead of 64 MB, and more multi-core headroom with 16 cores / 32 threads instead of 32/64. That extra cache should keep paying off in CPU-limited games and high-refresh builds.
