Quick Answers

So, is Core i5-10400F better than Celeron G5900?

Yes. Core i5-10400F is the better all-around CPU here. It gives you a 199.2% average FPS lead across 38 shared CPU game tests in our data, 261.4% better Geekbench multi-core, 385.8% higher 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 199.2% more average FPS across 38 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 261.4% better Geekbench multi-core, backed by 6 cores and 12 threads. It also has the larger cache pool with 500% larger total L3 cache (12 MB vs 2 MB).

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

Core i5-10400F is the better buy right now. Core i5-10400F comes in 220.0% more expensive on MSRP at $160 MSRP versus $50 MSRP, and it still gives you a 199.2% average FPS lead across 38 shared CPU game tests in our data. It is also 51.8% better value on MSRP (81.4 vs 53.6 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.

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 500% larger total L3 cache (12 MB vs 2 MB) and more multi-core headroom with 6 cores / 12 threads instead of 2/2. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
