Quick Answers

So, is Core i5-10400F better than Core i3-L13G4?

Yes. Core i5-10400F is the better all-around CPU here. It gives you a 430.0% average FPS lead across 50 shared CPU game tests in our data, 865.8% 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 430.0% 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 865.8% better PassMark, backed by 6 cores and 12 threads. It also has the larger cache pool with 200% larger total L3 cache (12 MB vs 4 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 at an unclear MSRP at $160 MSRP versus unclear MSRP, and it still gives you a 430.0% average FPS lead across 50 shared CPU game tests in our data. It is also 100.0% better value on MSRP (81.4 vs 0.0 PassMark/$), so you are getting the faster CPU without taking a value hit on paper. That said, if you already own a compatible FC-CSP1016 + DDR4 setup, Core i3-L13G4 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?

Core i5-10400F makes more sense long term for 2026 and beyond. You are getting 200% larger total L3 cache (12 MB vs 4 MB) and more multi-core headroom with 6 cores / 12 threads instead of 5/5. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
