Quick Answers

So, is EPYC 9355P better than Xeon 6747P?

It depends on what matters more to you. For gaming, EPYC 9355P is ahead with 12.8% higher max boost clock. For rendering, compiling, streaming, and heavier multitasking, Xeon 6747P pulls ahead with 4.6% better PassMark.

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

For streaming, content creation, and heavier multitasking, Xeon 6747P is the better fit. You are getting 4.6% better PassMark, backed by 48 cores and 96 threads.

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

EPYC 9355P is the smarter buy today. EPYC 9355P is $3,499 cheaper on MSRP at $2,998 MSRP versus $6,497 MSRP, and it gives you 12.8% higher max boost clock. The trade-off is that Xeon 6747P is still stronger for heavier multi-core work with 4.6% better PassMark. It is also 107.3% better value on MSRP (32.4 vs 15.7 PassMark/$), 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?

Xeon 6747P is the more future-proof choice for 2026 and beyond. You are getting a newer CPU generation (2025 vs 2024), more multi-core headroom with 48 cores / 96 threads instead of 32/64, and AVX-512 support for heavier modern compute workloads. 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.
