Intel® Core™ Ultra 5 135H

The Intel Core Ultra 5 135H is a mobile processor with a hybrid 14-core layout (4 performance cores + 8 efficiency cores) and 18 threads, built on the Meteor Lake architecture (Intel 4 process). It launched in Oct 2023. Clocks run from 1.7 GHz base to 4.6 GHz boost. A 18-MB L3 cache backs the cores (1.5 MB per core). It addresses LPDDR5, DDR5 memory up to 96 GB across 2 channels. The chip drops into the FCBGA2049 socket and exposes PCIe 5.0 (28 lanes). Rated TDP is 28 W. Notable platform capabilities: Gaussian Neural Accelerator, Extended Page Tables (EPT), Control-flow Enforcement (CET).

The Intel Core Ultra 5 135H scores 3,480 in single-core performance and 21,989 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 8,748 for overall performance, 19,165 for productivity performance, 18,358 for creator performance, 24,600 for engineering performance and 15,937 for gaming performance. Its multi-core throughput works out to 1,571 per core, 1,222 per thread and 785 per watt. Its computed efficiency index is 1,653. Its performance index is 108, so its overall performance is 8% above 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 Ultra 5 135H scores 72,929 in integer math, 54,116 in floating-point math, 246,836 in compression, 14,733 in cryptography, 1,444 in physics simulation, 14,678 in vector SIMD, 89 in the prime sieve and 28,183 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 24% above in integer math, 18% above in floating-point math, 8% above in compression, 28% above in cryptography, 32% above in physics simulation, 5% below in vector SIMD, 33% above in the prime sieve and 24% above 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 Ultra 5 135H has 14 physical cores and runs 18 logical threads. It uses a hybrid layout of 4 performance cores and 8 efficiency cores. It runs at a base clock of 1.70 GHz and boosts up to 4.60 GHz.
