Quick Answers

So, is Core Ultra 7 155H better than Core i5-12400F?

Yes. Core Ultra 7 155H is the better all-around CPU here. It gives you a 18.8% average FPS lead across 50 shared CPU game tests in our data, 42.6% better Cinebench R23 multi-core, 26.5% 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, Core Ultra 7 155H is the better pick. According to our tests, it delivers 18.8% 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, Core Ultra 7 155H is the stronger fit. You are getting 42.6% better Cinebench R23 multi-core, backed by 16 cores and 22 threads. It also has the larger cache pool with 33.3% larger total L3 cache (24 MB vs 18 MB).

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

Core Ultra 7 155H is still the faster CPU overall, but Core i5-12400F is easier to justify if budget matters more than peak performance. Core Ultra 7 155H comes in at an unclear MSRP at unclear MSRP versus $174 MSRP, and it still gives you a 18.8% average FPS lead across 50 shared CPU game tests in our data. Core i5-12400F is also 100.0% better value on MSRP (112.3 vs 0.0 PassMark/$), which is why it can still make sense for tighter-budget builds on paper.

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

Core Ultra 7 155H makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2023 vs 2022), 33.3% larger total L3 cache (24 MB vs 18 MB), and more multi-core headroom with 16 cores / 22 threads instead of 6/12. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
