Quick Answers

So, is Core Ultra 7 155H better than Core i7-9700K?

Yes. Core Ultra 7 155H is the better overall CPU here. You are getting a 49.8% average FPS lead across 5 shared CPU game tests in our data, 71.6% 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, Core Ultra 7 155H is the better pick here. According to our tests, it delivers 49.8% more average FPS across 5 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 better fit. You are getting 71.6% better PassMark, backed by 16 cores and 22 threads. It also carries the larger cache pool with 100% larger total L3 cache (24 MB vs 12 MB).

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

Core Ultra 7 155H is the smarter buy by a wide margin for a fresh build. Core Ultra 7 155H is at an unclear MSRP at unclear MSRP versus $385 MSRP, and it gives you a 49.8% average FPS lead across 5 shared CPU game tests in our data. Core i7-9700K only looks stronger on raw value math because it is extremely cheap, but that is mostly used-market pricing on an obsolete 2018 platform. Even with 100.0% better value on paper (37.4 vs 0.0 PassMark/$), it really only makes sense as a very cheap stopgap or a niche existing-platform option for someone already on LGA1151.

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

Core Ultra 7 155H is the more future-proof choice for 2026 and beyond. You are getting a newer CPU generation (2023 vs 2018), a healthier platform with FCBGA2049 and DDR5 instead of LGA1151, 100% larger total L3 cache (24 MB vs 12 MB), and more multi-core headroom with 16 cores / 22 threads instead of 8/8. That should give you a better long-term upgrade path for motherboard, RAM, and future CPU swaps.

Games Benchmarks
