Quick Answers

So, is EPYC 7573X better than EPYC 7543P?

Yes. EPYC 7573X is the better all-around CPU here. It gives you a 11.1% average FPS lead across 50 shared CPU game tests in our data, 4.3% 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 7573X is the better pick. According to our tests, it delivers 11.1% more average FPS across 50 shared CPU game tests.

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

For streaming, content creation, and heavier multitasking, EPYC 7573X is the stronger fit. You are getting 4.3% better PassMark, backed by 32 cores and 64 threads. It also has the larger cache pool with 200% larger total L3 cache (768 MB vs 256 MB).

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

EPYC 7573X is still the faster CPU overall, but EPYC 7543P is easier to justify if budget matters more than peak performance. EPYC 7573X comes in 104.8% more expensive on MSRP at $5,590 MSRP versus $2,730 MSRP, and it still gives you a 11.1% average FPS lead across 50 shared CPU game tests in our data. EPYC 7543P is also 96.4% better value on MSRP (24.4 vs 12.4 PassMark/$), which is why it can still make sense for tighter-budget builds on paper.

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

EPYC 7573X makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2022 vs 2021), 200% larger total L3 cache (768 MB vs 256 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.
