Quick Answers

So, is Core i5-12400F better than Athlon PRO 300GE?
Yes. Core i5-12400F is the better all-around CPU here. It gives you a 152.2% average FPS lead across 50 shared CPU game tests in our data, 349.8% 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 152.2% 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 349.8% better PassMark, backed by 6 cores and 12 threads. It also has the larger cache pool with 350% larger total L3 cache (18 MB vs 4 MB).
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 248.0% more expensive on MSRP at $174 MSRP versus $50 MSRP, and it still gives you a 152.2% average FPS lead across 50 shared CPU game tests in our data. It is also 29.3% better value on MSRP (112.3 vs 86.8 PassMark/$), 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, Athlon PRO 300GE 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 i5-12400F makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2022 vs 2019), a healthier platform with LGA1700 and DDR5 instead of AM4, 350% larger total L3 cache (18 MB vs 4 MB), and more multi-core headroom with 6 cores / 12 threads instead of 2/4. That gives you a healthier platform runway for motherboard, RAM, and later CPU upgrades.
