Yes. Ryzen 7 PRO 7840U is the better overall CPU here. You are getting a 16.7% average FPS lead across 49 shared CPU game tests in our data, 25.6% better PassMark, and the stronger long-term platform, which makes it the stronger all-around choice.

Which one is better for gaming?

If gaming is the priority, Ryzen 7 PRO 7840U is the better pick here. According to our tests, it delivers 16.7% more average FPS across 49 shared CPU game tests.

Which one is better for streaming, content creation, and heavy multitasking?

For streaming, content creation, and heavier multitasking, Ryzen 7 PRO 7840U is the better fit. You are getting 25.6% better PassMark, backed by 8 cores and 16 threads.

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

Ryzen 7 PRO 7840U is still the faster CPU overall, but Core i5-12400F makes more sense if price matters more than absolute performance. Ryzen 7 PRO 7840U is at an unclear MSRP at unclear MSRP versus $174 MSRP, and it gives you a 16.7% average FPS lead across 49 shared CPU game tests in our data. Core i5-12400F is also 100.0% better value on MSRP (112.3 vs 0.0 PassMark/$), which is why it is easier to justify for price-conscious builds on paper.

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

Ryzen 7 PRO 7840U is the more future-proof choice for 2026 and beyond. You are getting a newer CPU generation (2023 vs 2022) and more multi-core headroom with 8 cores / 16 threads instead of 6/12. That extra compute headroom should age better as games, background tasks, and creator workloads get heavier.
