Intel® Core™ Ultra 7 366H

The Intel Core Ultra 7 366H is a mobile processor with a hybrid 16-core layout (4 performance cores + 8 efficiency cores) and 16 threads, built on the Panther Lake architecture. It launched in Jan 2026. Clocks run from 2.0 GHz base to 4.8 GHz boost. A 18-MB L3 cache backs the cores (1.4 MB per core). It addresses LPDDR5X, DDR5 memory up to 128 GB across 2 channels. The chip drops into the FCBGA2540 socket and exposes PCIe 5.0 (20 lanes). Rated TDP is 25 W. Notable platform capabilities: Extended Page Tables (EPT), Control-flow Enforcement (CET).

The Intel Core Ultra 7 366H scores 4,049 in single-core performance and 34,234 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 11,773 for overall performance, 27,921 for productivity performance, 26,117 for creator performance, 39,369 for engineering performance and 20,706 for gaming performance. Its multi-core throughput works out to 2,140 per core, 2,140 per thread and 1,369 per watt. Its computed efficiency index is 2,355. Its performance index is 146, so its overall performance is 46% 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 7 366H scores 84,385 in integer math, 105,144 in floating-point math, 333,856 in compression, 26,433 in cryptography, 2,937 in physics simulation, 27,607 in vector SIMD, 332 in the prime sieve and 40,565 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 43% above in integer math, 129% above in floating-point math, 46% above in compression, 130% above in cryptography, 169% above in physics simulation, 78% above in vector SIMD, 396% above in the prime sieve and 79% 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 7 366H has 16 physical cores and runs 16 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 2.00 GHz and boosts up to 4.80 GHz.

The Intel Core Ultra 7 366H is a mobile processor, belongs to the Intel Core Ultra 7 family, uses the Panther Lake architecture, carries the codename Panther Lake and is manufactured on a 2 nm process. It launched in Jan 2026.

The Intel Core Ultra 7 366H has 1.56 MB of L1 cache, 2.50 MB of L2 cache and 18 MB of L3 cache. That adds up to about 22.1 MB of cache, or 1.38 MB per core.

The Intel Core Ultra 7 366H has a 3-level cache hierarchy: L1 at 1.6 MB, L2 at 2.5 MB and L3 at 18 MB. L3 is the largest level and makes up about 82% of the cache listed here.

The Intel Core Ultra 7 366H supports LPDDR5X, DDR5 memory, addresses up to 128 GB of memory and uses 2 memory channels. It does not support DDR4 memory.
