Intel® Core™ Ultra 9 285H

The Intel Core Ultra 9 285H is a mobile processor with a hybrid 16-core layout (6 performance cores + 8 efficiency cores) and 16 threads, built on the Arrow Lake architecture. It launched in Jan 2025. Clocks run from 2.9 GHz base to 5.4 GHz boost. A 24-MB L3 cache backs the cores (1.7 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 45 W. Notable platform capabilities: Gaussian Neural Accelerator, Extended Page Tables (EPT), Control-flow Enforcement (CET).

The Intel Core Ultra 9 285H scores 4,432 in single-core performance and 34,283 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 12,326 for overall performance, 28,489 for productivity performance, 26,833 for creator performance, 39,425 for engineering performance and 21,867 for gaming performance. Its multi-core throughput works out to 2,143 per core, 2,143 per thread and 762 per watt. Its computed efficiency index is 1,838. Its performance index is 153, so its overall performance is 53% 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 9 285H scores 86,006 in integer math, 109,329 in floating-point math, 336,081 in compression, 26,164 in cryptography, 2,516 in physics simulation, 26,817 in vector SIMD, 330 in the prime sieve and 40,973 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 46% above in integer math, 138% above in floating-point math, 47% above in compression, 128% above in cryptography, 131% above in physics simulation, 73% above in vector SIMD, 393% above in the prime sieve and 81% 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 9 285H has 16 physical cores and runs 16 logical threads. It uses a hybrid layout of 6 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 2.90 GHz and boosts up to 5.40 GHz.

The Intel Core Ultra 9 285H is a mobile processor, belongs to the Intel Core Ultra 9 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 9 285H has 1.59 MB of L1 cache, 2 MB of L2 cache and 24 MB of L3 cache. That adds up to about 27.6 MB of cache, or 1.72 MB per core.

The Intel Core Ultra 9 285H has a 3-level cache hierarchy: L1 at 1.6 MB, L2 at 2 MB and L3 at 24 MB. L3 is the largest level and makes up about 87% of the cache listed here.

The Intel Core Ultra 9 285H 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.
