Quick Answers

So, is M3 Max 14-Core better than Core i5-10400F?

Yes. M3 Max 14-Core is the better all-around CPU here. It gives you a 14.8% average FPS lead across 50 shared CPU game tests in our data, 180.4% 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, M3 Max 14-Core is the better pick. According to our tests, it delivers 14.8% 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, M3 Max 14-Core is the stronger fit. You are getting 180.4% better PassMark, backed by 14 cores and 14 threads.

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

M3 Max 14-Core is still the faster CPU overall, but Core i5-10400F is easier to justify if budget matters more than peak performance. M3 Max 14-Core comes in at an unclear MSRP at unclear MSRP versus $160 MSRP, and it still gives you a 14.8% average FPS lead across 50 shared CPU game tests in our data. Core i5-10400F is also 100.0% better value on MSRP (81.4 vs 0.0 PassMark/$), which is why it can still make sense for tighter-budget builds on paper. That said, if you already own a compatible LGA1200 + DDR4 setup, Core i5-10400F 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?

M3 Max 14-Core makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2023 vs 2020), a healthier platform with none and DDR5 instead of LGA1200, and more multi-core headroom with 14 cores / 14 threads instead of 6/12. That gives you a healthier platform runway for motherboard, RAM, and later CPU upgrades.
