Intel Core i7-1260U vs Intel Core i7-1280P: Comparison
Core i7-1260U vs Core i7-1280P: the l3 cache difference
The gap that matters here is l3 cache: Core i7-1260U 12 MB against Core i7-1280P 24 MB, which puts Core i7-1280P 50% ahead. E-core boost clock is not the same on both, 3.3 GHz on the Core i7-1260U versus 3.6 GHz on the Core i7-1280P. They differ on p-core base clock too, 1.1 GHz on the Core i7-1260U versus 1.8 GHz on the Core i7-1280P. There is a split on e-core base clock as well, 0.8 GHz on the Core i7-1260U versus 1.3 GHz on the Core i7-1280P. They differ on tdp too, 9 W on the Core i7-1260U versus 28 W on the Core i7-1280P.
Who each one is for
The Core i7-1260U is the one to take for ultra-thin laptops and business laptops, though it is not built for gaming laptops and heavy sustained workloads. The Core i7-1280P suits thin-and-light laptops and everyday productivity, though it is not the pick for gaming laptops and heavy sustained workloads. Our rating of the Core i7-1260U (7.7/10): the Intel Core i7-1260U prioritizes battery life and portability, fitting thin business and everyday laptops rather than performance-first designs. Our rating of the Core i7-1280P (8/10): the Intel Core i7-1280P balances performance and efficiency, a solid pick for mainstream thin-and-light laptops.
Where the two are identical
