Quick Answers

So, is EPYC 9355P better than Core i5-10400F?

Not really, because they are built for different jobs. EPYC 9355P makes more sense for workstation-style multi-core throughput, while Core i5-10400F is the more practical desktop choice for gaming, platform cost, and everyday use.

Which one is better for gaming?

If gaming is the priority, EPYC 9355P is the better pick. According to our tests, it delivers 43.2% more average FPS across 50 shared CPU game tests. It also has a clear cache advantage at 256 MB versus 12 MB.

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

For streaming, content creation, and heavier multitasking, EPYC 9355P is the stronger fit. You are getting 646.4% better PassMark, backed by 32 cores and 64 threads. It also has 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 9355P is still the faster CPU overall, but Core i5-10400F is easier to justify if budget matters more than peak performance. EPYC 9355P comes in 1773.8% more expensive on MSRP at $2,998 MSRP versus $160 MSRP, and it still gives you a 43.2% average FPS lead across 50 shared CPU game tests in our data. Core i5-10400F is also 151.0% better value on MSRP (81.4 vs 32.4 PassMark/$), which is why it can still make sense for tighter-budget builds on paper.

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

EPYC 9355P makes more sense long term 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 32 cores / 64 threads instead of 6/12. That gives you a healthier platform runway for motherboard, RAM, and later CPU upgrades.
