Quick Answers

So, is Core i5-12400F better than A12-9800E?

Yes. Core i5-12400F is the better all-around CPU here. It gives you a 183.0% average FPS lead across 50 shared CPU game tests in our data, 471.8% 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 i5-12400F is the better pick. According to our tests, it delivers 183.0% 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 i5-12400F is the stronger fit. You are getting 471.8% better PassMark, backed by 6 cores and 12 threads.

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

Core i5-12400F is the better buy right now. Core i5-12400F comes in $252 cheaper on MSRP at $174 MSRP versus $426 MSRP, and it still gives you a 183.0% average FPS lead across 50 shared CPU game tests in our data. It is also 1299.9% better value on MSRP (112.3 vs 8.0 PassMark/$), so you are getting the faster CPU without taking a value hit on paper. That said, if you already own a compatible AM4 + DDR4 setup, A12-9800E can still make sense as a platform-matched option because it avoids a motherboard and RAM swap, but on MSRP alone you would want to find it meaningfully cheaper in real-world listings before that path becomes easy to justify.

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

Core i5-12400F makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2022 vs 2017), a healthier platform with LGA1700 and DDR5 instead of AM4, and more multi-core headroom with 6 cores / 12 threads instead of 4/4. That gives you a healthier platform runway for motherboard, RAM, and later CPU upgrades.
