Intel® Core™ Ultra 5 225H

The Intel Core Ultra 5 225H is a mobile processor with a hybrid 14-core layout (4 performance cores + 8 efficiency cores) and 14 threads, built on the Arrow Lake architecture. It launched in Jan 2025. Clocks run from 1.7 GHz base to 4.9 GHz boost. A 18-MB L3 cache backs the cores (1.5 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 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 225H scores 4,267 in single-core performance and 28,419 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 11,012 for overall performance, 24,446 for productivity performance, 23,311 for creator performance, 31,794 for engineering performance and 19,906 for gaming performance. Its multi-core throughput works out to 2,030 per core, 2,030 per thread and 1,015 per watt. Its computed efficiency index is 2,081. Its performance index is 136, so its overall performance is 36% 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 225H scores 68,599 in integer math, 86,596 in floating-point math, 283,423 in compression, 21,424 in cryptography, 1,880 in physics simulation, 21,922 in vector SIMD, 221 in the prime sieve and 33,651 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 16% above in integer math, 89% above in floating-point math, 24% above in compression, 86% above in cryptography, 72% above in physics simulation, 41% above in vector SIMD, 230% above in the prime sieve and 49% 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 225H has 14 physical cores and runs 14 logical threads. It uses a hybrid layout of 4 performance cores and 8 efficiency cores. It does not support simultaneous multithreading, so its thread count equals its core count. It runs at a base clock of 1.70 GHz and boosts up to 4.90 GHz.

The Intel Core Ultra 5 225H is a mobile processor, belongs to the Intel Core Ultra 5 family, uses the Arrow Lake architecture, carries the codename Arrow Lake and is manufactured on a 3 nm process. It launched in Jan 2025.

The Intel Core Ultra 5 225H has 1.38 MB of L1 cache, 2 MB of L2 cache and 18 MB of L3 cache. That adds up to about 21.4 MB of cache, or 1.53 MB per core.

The Intel Core Ultra 5 225H has a 3-level cache hierarchy: L1 at 1.4 MB, L2 at 2 MB and L3 at 18 MB. L3 is the largest level and makes up about 84% of the cache listed here.

The Intel Core Ultra 5 225H supports LPDDR5, DDR5 memory, addresses up to 128 GB of memory, uses 2 memory channels and runs memory at up to 6,400 MT/s. It does not support DDR4 memory. It does not support ECC memory.
