Quick Answers

So, is EPYC 9255 better than Core i5-13400F?

Not in a simple one-size-fits-all way. EPYC 9255 makes more sense for workstation-style multi-core throughput, while Core i5-13400F is the better mainstream desktop choice for gaming, platform cost, and day-to-day practicality.

Which one is better for gaming?

If gaming is the priority, EPYC 9255 is the better pick here. According to our tests, it delivers 30.9% more average FPS across 4 shared CPU game tests. It also has a big cache advantage at 128 MB vs 20 MB.

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

For streaming, content creation, and heavier multitasking, EPYC 9255 is the better fit. You are getting 202.9% better PassMark, backed by 24 cores and 48 threads. It also carries the larger cache pool with 540% larger total L3 cache (128 MB vs 20 MB).

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

EPYC 9255 is still the faster CPU overall, but Core i5-13400F makes more sense if price matters more than absolute performance. EPYC 9255 is 1173.0% more expensive on MSRP at $2,495 MSRP versus $196 MSRP, and it gives you a 30.9% average FPS lead across 4 shared CPU game tests in our data. Core i5-13400F is also 320.3% better value on MSRP (127.7 vs 30.4 PassMark/$), which is why it is easier to justify for price-conscious builds on paper.

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

EPYC 9255 is the more future-proof choice for 2026 and beyond. You are getting a newer CPU generation (2024 vs 2023), 3D V-Cache and a much larger 128 MB L3 cache instead of 20 MB, more multi-core headroom with 24 cores / 48 threads instead of 10/16, and AVX-512 support for heavier modern compute workloads. That should give you a better long-term upgrade path for motherboard, RAM, and future CPU swaps.

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.
