Intel Core Ultra 7 255H vs Intel Core Ultra 9 285H: Comparison
What is the difference between Core Ultra 7 255H and Core Ultra 9 285H?
The first real difference is p-core boost clock: Core Ultra 7 255H 5.1 GHz against Core Ultra 9 285H 5.4 GHz. Cinebench 2024 (Multi-Core) backs the spec sheet up. Core Ultra 9 285H scores 1,114 to 1,019, 9% clear. There is a split on npu peak tops as well, 13 TOPS on the Core Ultra 7 255H versus 11 TOPS on the Core Ultra 9 285H.
Core Ultra 7 255H vs Core Ultra 9 285H: which one fits your build
Buy the Core Ultra 7 255H for premium thin laptops for work and creative apps and gaming laptops paired with a dedicated GPU, though it is the wrong buy for copilot+ PC AI features, which need a 40+ TOPS NPU and demanding games on integrated graphics alone. It is not the one for buyers who want the longest battery life, where 200V laptops fit better. The Core Ultra 9 285H is the one to take for everyday laptop computing and on-device AI features, though it is not built for gaming laptops and heavy sustained workloads. Our rating of the Core Ultra 9 285H (8.3/10): the Intel Core Ultra 9 285H is a performance-oriented Meteor Lake mobile chip, well suited to premium laptops.
Where the two are identical
Everything else lines up. Total cores, performance cores, efficiency cores, total threads and l3 cache read the same on both, so those are not worth weighing. They match on 8 further specifications as well.
Do the Core Ultra 7 255H and Core Ultra 9 285H differ on p-core base clock?
Yes. P-Core Base Clock reads 2 GHz on the Core Ultra 7 255H versus 2.9 GHz on the Core Ultra 9 285H.
Is the Socket the same on the Core Ultra 7 255H and Core Ultra 9 285H?
It is. Both are listed at FCBGA2049, so it is not a reason to pick one over the other.
