Quick Answers

So, is Ryzen 5 8645HS better than Core i5-12400F?

Yes. Ryzen 5 8645HS is the better all-around CPU here. It gives you a 12.4% average FPS lead across 50 shared CPU game tests in our data, 7.6% better Cinebench R23 multi-core, 14.0% higher 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, Ryzen 5 8645HS is the better pick. According to our tests, it delivers 12.4% 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, Ryzen 5 8645HS is the stronger fit. You are getting 7.6% better Cinebench R23 multi-core, backed by 6 cores and 12 threads.

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

Ryzen 5 8645HS is still the faster CPU overall, but Core i5-12400F is easier to justify if budget matters more than peak performance. Ryzen 5 8645HS comes in at an unclear MSRP at unclear MSRP versus $174 MSRP, and it still gives you a 12.4% average FPS lead across 50 shared CPU game tests in our data. Core i5-12400F is also 100.0% better value on MSRP (112.3 vs 0.0 PassMark/$), which is why it can still make sense for tighter-budget builds on paper.

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

Ryzen 5 8645HS makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2023 vs 2022) and more multi-core headroom with 6 cores / 12 threads instead of 6/12. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
