Quick Answers

So, is Core i5-10400F better than Ryzen 3 3100?
Yes. Core i5-10400F is the better overall CPU here. You are getting a 8.0% average FPS lead across 5 shared CPU game tests in our data, 9.2% 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, Core i5-10400F is the better pick here. According to our tests, it delivers 8.0% more average FPS across 5 shared CPU game tests.
Which one is better for streaming, content creation, and heavy multitasking?
For streaming, content creation, and heavier multitasking, Core i5-10400F is the better fit. You are getting 9.2% better PassMark, backed by 6 cores and 12 threads.
Which one is the smarter buy today, not just the cheaper CPU?
Core i5-10400F is the smarter buy by a wide margin for a fresh build. Core i5-10400F is 61.6% more expensive on MSRP at $160 MSRP versus $99 MSRP, and it gives you a 8.0% average FPS lead across 5 shared CPU game tests in our data. Ryzen 3 3100 only looks stronger on raw value math because it is so cheap, but its absolute performance tier is too low to be the smarter recommendation now. At roughly 11,928 PassMark with 4 cores and 8 threads, it only makes sense as a bare-minimum stopgap or a very constrained existing-platform upgrade.
Which one is more future-proof for 2026 and beyond?
Core i5-10400F is the more future-proof choice for 2026 and beyond. You are getting more multi-core headroom with 6 cores / 12 threads instead of 4/8. That extra compute headroom should age better as games, background tasks, and creator workloads get heavier.

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.
