Quick Answers

So, is Core Ultra 7 155H better than Ryzen Z1 Extreme?

It depends on what you want from the system. For gaming, Ryzen Z1 Extreme is ahead with a 2.5% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Core Ultra 7 155H pulls ahead with 0.1% better PassMark. Core Ultra 7 155H also has the bigger cache pool with 50% larger total L3 cache (24 MB vs 16 MB).

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 0.1% better PassMark, backed by 16 cores and 22 threads. It also has the larger cache pool with 50% larger total L3 cache (24 MB vs 16 MB).

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

Core Ultra 7 155H still makes the most sense overall. Core Ultra 7 155H comes in at an unclear MSRP at unclear MSRP versus unclear MSRP, and it still gives you 0.1% better PassMark.

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 50% larger total L3 cache (24 MB vs 16 MB) and more multi-core headroom with 16 cores / 22 threads instead of 8/16. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
