Quick Answers

So, is Core i5-10400F better than Core 2 Quad Q9100?

Yes. Core i5-10400F is the better all-around CPU here. It gives you a 299.6% average FPS lead across 50 shared CPU game tests in our data, 621.4% better PassMark, and the stronger long-term platform, which is enough to make it the stronger overall pick.

Which one is better for gaming?

If gaming is the priority, Core i5-10400F is the better pick. According to our tests, it delivers 299.6% more average FPS across 50 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 stronger fit. You are getting 621.4% 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 still the much better call for a fresh build. Core i5-10400F comes in 1042.9% more expensive on MSRP at $160 MSRP versus $14 MSRP, and it still gives you a 299.6% average FPS lead across 50 shared CPU game tests in our data. Core 2 Quad Q9100 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2008 platform. Even with 58.4% better value on paper (129.0 vs 81.4 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on PGA478.

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

Core i5-10400F makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2020 vs 2008) and more multi-core headroom with 6 cores / 12 threads instead of 4/4. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
