EPYC 9684X also has the bigger cache pool with 200% larger total L3 cache (1.1 GB vs 384 MB).
Which one is better for streaming, content creation, and heavy multitasking?
For streaming, content creation, and heavier multitasking, EPYC 9684X is the better fit. You are getting 13% better PassMark, backed by 96 cores and 192 threads. It also carries the larger cache pool with 200% larger total L3 cache (1.1 GB vs 384 MB).
Which one is the smarter buy today, not just the cheaper CPU?
EPYC 9634 is the smarter buy today. EPYC 9634 is $4,452 cheaper on MSRP at $10,304 MSRP versus $14,756 MSRP, and it gives you a 7.2% average FPS lead across 50 shared CPU game tests in our data. The trade-off is that EPYC 9684X is still stronger for heavier multi-core work with 13% better PassMark. It is also 26.7% better value on MSRP (10.5 vs 8.3 PassMark/$), 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 9684X is the more future-proof choice for 2026 and beyond. You are getting a newer CPU generation (2023 vs 2022), 200% larger total L3 cache (1.1 GB vs 384 MB), and more multi-core headroom with 96 cores / 192 threads instead of 84/168. 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.
