Intel Core Ultra 7 155U vs Intel Core Ultra 7 366H: Comparison
Core Ultra 7 155U vs Core Ultra 7 366H l3 cache compared
On l3 cache the spread is 33%, Core Ultra 7 155U 12 MB against Core Ultra 7 366H 18 MB, so Core Ultra 7 366H takes it. They differ on tdp too, 15 W on the Core Ultra 7 155U versus 25 W on the Core Ultra 7 366H. There is a split on socket as well, FCBGA2049 on the Core Ultra 7 155U versus FCBGA2540 on the Core Ultra 7 366H. Release year is not the same on both, 2023 on the Core Ultra 7 155U versus 2026 on the Core Ultra 7 366H.
Who each one is for
The Core Ultra 7 155U 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. Take the Core Ultra 7 366H for gaming and creator laptops that pair 16 cores with a discrete GPU, using 20 PCIe lanes. It also earns its place with buyers wanting a 4.8 GHz boost clock and a 50 TOPS NPU in the 16-core H tier. Avoid it for thin laptops depending on integrated graphics, because it has a smaller 4 Xe3-core iGPU. Our rating of the Core Ultra 7 155U (7.9/10): the Intel Core Ultra 7 155U is a efficiency-oriented Meteor Lake mobile chip, well suited to thin-and-light everyday laptops.
Where the two are identical
Where they agree, they agree completely, p-core boost clock, integrated graphics, form factor and market segment included, so the decision does not turn on any of those.
Do the Core Ultra 7 155U and Core Ultra 7 366H differ on total cores?
