Quick Answers

So, is EPYC 9745 better than Core i5-10400F?

Not in a simple one-size-fits-all way. EPYC 9745 makes more sense for workstation-style multi-core throughput, while Core i5-10400F 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 9745 is the better pick here. According to our tests, it delivers 18.3% more average FPS across 50 shared CPU game tests. It also has a big cache advantage at 256 MB vs 12 MB.

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

For streaming, content creation, and heavier multitasking, EPYC 9745 is the better fit. You are getting 903.1% better PassMark, backed by 128 cores and 256 threads. It also carries the larger cache pool with 2033.3% larger total L3 cache (256 MB vs 12 MB).

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

EPYC 9745 is still the faster CPU overall, but Core i5-10400F makes more sense if price matters more than absolute performance. EPYC 9745 is 7488.1% more expensive on MSRP at $12,141 MSRP versus $160 MSRP, and it gives you a 18.3% average FPS lead across 50 shared CPU game tests in our data. Core i5-10400F is also 656.4% better value on MSRP (81.4 vs 10.8 PassMark/$), 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 9745 is the more future-proof choice for 2026 and beyond. You are getting a newer CPU generation (2024 vs 2020), a healthier platform with SP5 and DDR5 instead of LGA1200, 3D V-Cache and a much larger 256 MB L3 cache instead of 12 MB, and more multi-core headroom with 128 cores / 256 threads instead of 6/12. 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.
