Intel® Core™ Ultra 5 235U

The Intel Core Ultra 5 235U is a mobile processor with a hybrid 12-core layout (2 performance cores + 8 efficiency cores) and 14 threads, built on the Arrow Lake architecture. It launched in Jan 2025. Clocks run from 2.0 GHz base to 4.9 GHz boost. A 12-MB L3 cache backs the cores (1.3 MB per core). It addresses LPDDR5, DDR5 memory up to 128 GB across 2 channels. The chip drops into the FCBGA2049 socket and exposes PCIe 4.0 (20 lanes). Rated TDP is 15 W. Notable platform capabilities: Gaussian Neural Accelerator, Extended Page Tables (EPT), Control-flow Enforcement (CET).

The Intel Core Ultra 5 235U scores 3,596 in single-core performance and 17,576 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 7,950 for overall performance, 16,459 for productivity performance, 16,140 for creator performance, 19,114 for engineering performance and 15,182 for gaming performance. Its multi-core throughput works out to 1,465 per core, 1,255 per thread and 1,172 per watt. Its computed efficiency index is 2,053. Its performance index is 99, so its overall performance is 1% 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 Ultra 5 235U scores 63,502 in integer math, 44,740 in floating-point math, 193,013 in compression, 12,171 in cryptography, 1,067 in physics simulation, 10,768 in vector SIMD, 60 in the prime sieve and 20,966 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 8% above in integer math, 3% below in floating-point math, 15% below in compression, 6% above in cryptography, 2% below in physics simulation, 31% below in vector SIMD, 10% below in the prime sieve and 7% 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.
