Intel® Core™ i7-1260U

The Intel Core i7-1260U is a laptop processor with a hybrid 10-core layout (2 performance cores + 8 efficiency cores) and 12 threads, built on the Alder Lake architecture (Intel 7 process). It launched in Jan 2022. Clocks run from 1.6 GHz base to 4.7 GHz boost. A 12-MB L3 cache backs the cores (1.9 MB per core). It addresses LPDDR5, LPDDR4X memory up to 64 GB across 2 channels. It uses the FCBGA1781 socket. Rated TDP is 9 W. Notable platform capabilities: Deep Learning Boost, AVX-VNNI, Extended Page Tables (EPT), AES-NI.

The Intel Core i7-1260U scores 3,039 in single-core performance and 13,268 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 6,350 for overall performance, 12,879 for productivity performance, 12,768 for creator performance, 14,014 for engineering performance and 12,434 for gaming performance. Its multi-core throughput works out to 1,327 per core, 1,106 per thread and 1,474 per watt. Its computed efficiency index is 2,117. Its performance index is 79, so its overall performance is 21% below the Intel Core i5-12400 (index 100). Each bar shows the score as a share of a reference ceiling, which is the larger of the 99th-percentile score across the Feex CPU database and a fixed baseline.

Scores for individual PassMark CPU Mark test categories. Higher is better. These are measured test scores, not computed from the single-core and multi-core ratings.

In the individual workload tests the Intel Core i7-1260U scores 44,515 in integer math, 29,904 in floating-point math, 142,889 in compression, 8,874 in cryptography, 996 in physics simulation, 7,815 in vector SIMD, 64 in the prime sieve and 15,803 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 24% below in integer math, 35% below in floating-point math, 37% below in compression, 23% below in cryptography, 9% below in physics simulation, 50% below in vector SIMD, 4% below in the prime sieve and 30% below in sorting. Each bar shows the score as a share of that workload's reference ceiling, the larger of the 99th-percentile score across CPUs with a recorded value and a fixed baseline.

The Intel Core i7-1260U has 10 physical cores and runs 12 logical threads. It uses a hybrid layout of 2 performance cores and 8 efficiency cores. It runs at a base clock of 1.60 GHz and boosts up to 4.70 GHz.
