Quick Answers

So, is EPYC 7773X better than Core i5-10400F?

Not in a simple one-size-fits-all way. EPYC 7773X 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 7773X is the better pick here. According to our tests, it delivers 32.1% more average FPS across 50 shared CPU game tests. It also has a big cache advantage at 768 MB vs 12 MB.

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

For streaming, content creation, and heavier multitasking, EPYC 7773X is the better fit. You are getting 678.1% better Geekbench multi-core, backed by 64 cores and 128 threads. It also carries the larger cache pool with 6300% larger total L3 cache (768 MB vs 12 MB).

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

EPYC 7773X is still the faster CPU overall, but Core i5-10400F makes more sense if price matters more than absolute performance. EPYC 7773X is 5400.0% more expensive on MSRP at $8,800 MSRP versus $160 MSRP, and it gives you a 32.1% average FPS lead across 50 shared CPU game tests in our data. Core i5-10400F is also 684.5% better value on MSRP (81.4 vs 10.4 PassMark/$), 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 7773X is the more future-proof choice for 2026 and beyond. You are getting a newer CPU generation (2022 vs 2020), 3D V-Cache and a much larger 768 MB L3 cache instead of 12 MB, and more multi-core headroom with 64 cores / 128 threads instead of 6/12. 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.
