Quick Answers

So, is Core i5-10400F better than Core i3-12100T?

Yes. Core i5-10400F is the better all-around CPU here. It gives you a 5.6% average FPS lead across 50 shared CPU game tests in our data and 4.3% better PassMark, 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 5.6% 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 4.3% 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 faster CPU overall, but Core i3-12100T is easier to justify if budget matters more than peak performance. Core i5-10400F comes in 28.0% more expensive on MSRP at $160 MSRP versus $125 MSRP, and it still gives you a 5.6% average FPS lead across 50 shared CPU game tests in our data. Core i3-12100T is also 22.7% better value on MSRP (99.9 vs 81.4 PassMark/$), which is why it can still make sense for tighter-budget builds on paper. That said, if you already own a compatible LGA1700 + DDR5 setup, Core i3-12100T 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 i3-12100T makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2022 vs 2020) and a healthier platform with LGA1700 and DDR5 instead of LGA1200. That gives you a healthier platform runway for motherboard, RAM, and later CPU upgrades.
