Intel Core Ultra 7 255H vs Intel Core Ultra 7 265H: Comparison
Core Ultra 7 255H vs Core Ultra 7 265H p-core boost clock compared
The first real difference is p-core boost clock: Core Ultra 7 255H 5.1 GHz against Core Ultra 7 265H 5.3 GHz. Measured rather than claimed: in Geekbench 6 (Single-Core) the Core Ultra 7 265H returns 2,897 against 2,806, a 3% lead. There is a split on e-core boost clock as well, 4.4 GHz on the Core Ultra 7 255H versus 4.5 GHz on the Core Ultra 7 265H. P-core base clock is not the same on both, 2 GHz on the Core Ultra 7 255H versus 2.2 GHz on the Core Ultra 7 265H. They differ on e-core base clock too, 1.5 GHz on the Core Ultra 7 255H versus 1.7 GHz on the Core Ultra 7 265H.
Who each one is for
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 not built for copilot+ PC AI features, which need a 40+ TOPS NPU and demanding games on integrated graphics alone. It is the wrong buy for buyers who want the longest battery life, where 200V laptops fit better. The Core Ultra 7 265H is the one to take for premium business laptops managed with Intel vPro and mobile workstations for engineering, coding and video editing, though it is not the pick for copilot+ PC AI features, which need a 40+ TOPS NPU and demanding games on integrated graphics alone. Avoid it for home buyers who do not need vPro, where the 255H costs less.
Where the two are identical
Where they agree, they agree completely, total cores, performance cores, efficiency cores, low power cores and total threads included, so the decision does not turn on any of those. They match on 28 further specifications as well.
Is the TDP the same on the Core Ultra 7 255H and Core Ultra 7 265H?
It is. Both are listed at 28 W, so it is not a reason to pick one over the other.
