Quick Answers

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

It depends on what matters more to you. For gaming, EPYC 7543P is ahead with a 0.9% average FPS lead across 4 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, EPYC 7573X pulls ahead with 4.3% better PassMark. EPYC 7573X also has the bigger cache pool with 200% larger total L3 cache (768 MB vs 256 MB).

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

For streaming, content creation, and heavier multitasking, EPYC 7573X is the better fit. You are getting 4.3% better PassMark, backed by 32 cores and 64 threads. It also carries 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 7543P is the smarter buy today. EPYC 7543P is $2,860 cheaper on MSRP at $2,730 MSRP versus $5,590 MSRP, and it gives you a 0.9% average FPS lead across 4 shared CPU game tests in our data. The trade-off is that EPYC 7573X is still stronger for heavier multi-core work with 4.3% better PassMark. It is also 96.4% better value on MSRP (24.4 vs 12.4 PassMark/$), so the better CPU is not just faster, it is also the cleaner value play on paper.

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

EPYC 7573X is the more future-proof choice 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 hold up really well in CPU-limited games and high-refresh builds.

Games Benchmarks

Paired with RTX 4090

To accurately isolate CPU performance, all benchmarks below use an NVIDIA RTX 4090 as the reference GPU. This eliminates GPU-side bottlenecks and highlights pure processing throughput differences between the CPUs.

Note: Real-world results may vary based on your actual GPU. CPU performance impact is more visible in processing-intensive titles and high-refresh-rate gaming scenarios.
