Quick Answers

So, is Ryzen 5 8400F better than Core i5-10400F?

Yes. Ryzen 5 8400F is the better overall CPU here. You are getting a 56.0% average FPS lead across 4 shared CPU game tests in our data, 88.5% better PassMark, and the stronger long-term platform, which makes it the stronger all-around choice.

Which one is better for gaming?

If gaming is the priority, Ryzen 5 8400F is the better pick here. According to our tests, it delivers 56.0% more average FPS across 4 shared CPU game tests.

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

For streaming, content creation, and heavier multitasking, Ryzen 5 8400F is the better fit. You are getting 88.5% better PassMark, backed by 6 cores and 12 threads. It also carries the larger cache pool with 33.3% larger total L3 cache (16 MB vs 12 MB).

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

Ryzen 5 8400F is still the faster CPU overall, but Core i5-10400F makes more sense if price matters more than absolute performance. Ryzen 5 8400F is 89.4% more expensive on MSRP at $303 MSRP versus $160 MSRP, and it gives you a 56.0% average FPS lead across 4 shared CPU game tests in our data. Core i5-10400F is also 0.5% better value on MSRP (81.4 vs 81.0 PassMark/$), which is why it is easier to justify for price-conscious builds on paper. That said, if you already own a compatible LGA1200 + DDR4 setup, Core i5-10400F can still make sense as a platform-matched option because it avoids a motherboard and RAM swap.

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

Ryzen 5 8400F is the more future-proof choice for 2026 and beyond. You are getting a newer CPU generation (2024 vs 2020), a healthier platform with AM5 and DDR5 instead of LGA1200, 33.3% larger total L3 cache (16 MB vs 12 MB), and more multi-core headroom with 6 cores / 12 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.
