Intel Core Ultra 7 255H vs Intel Core Ultra 9 285H vs Intel Core Ultra 7 265H
Intel Core Ultra 7 255H
► remove from comparison
The Intel Core Ultra 7 255H is a mobile high-end CPU for larger notebooks based on the Arrow Lake architecture. It offers 16 cores consisting of 6 fast performance cores (Lion Cove) with up to 5.1 GHz and 8 smaller efficiency cores (Skymont) with up to 4.4 GHz clock speed and two additional "low power" efficiency cores with up to 2.5 GHz (Skymont). The CPU has access to 24 MB of cache and is specified with a TDP of 28 watt (PL1, 115W PL2).
The SoC integrates a small dedicated NPU called AI Boost with 13 TOPS (Int8) and optionally supports vPro Essentials. The integrated memory controller supports up to 192 GB LPDDR5/x-8400 or DDR5-6400 (dual channel). The integrated GPU (iGPU) is an Intel Arc 140T graphics card which offers eight Xe cores with up to 2.25 GHz.
Performance - High End
The Core Ultra 7 is superior to the top model Core Ultra 9 285H as only the maximum Turbo frequency is 200 MHz lower. Due to the improved IPC of the cores (especially the efficiency cores), the CPU should perform slightly below the level of the old Raptor Lake Core Core 9 270H (6 + 8 cores, max 5.8 / 4.1 GHz). This makes the CPU very suitable for demanding tasks such as high-end gaming and content creation.
Chiplet design
Like the desktop and HX chips, the Arrow Lake-H chips are based on individual chiplets that are placed on a 22nm base tile from Intel using Foveros 3D packaging. The CPU part comes from TSMC using the modern N3B (3nm) process. As with HX, the GPU also is produced at TSMC and is manufactured using the N5P process. SoC and I/O Tile are also from TSMC but in the older N6 process.

It offers 16 cores consisting of 6 fast performance cores (Lion Cove) with up to 5.4 GHz and 8 smaller efficiency cores (Skymont) with up to 4.5 GHz clock speed and two additional low power cores with up to 2.5 GHz (Skymont). The CPU has access to 24 MB of cache and is specified with a TDP of 45 watts.
The SoC integrates a small dedicated NPU called AI Boost with 13 TOPS (Int8) and optionally supports vPro Enterprise. The integrated memory controller supports up to 192 GB LPDDR5/x-8400 or DDR5-6400 (dual channel). The integrated GPU (iGPU) is an Intel Arc 140T graphics card that offers eight Xe cores with up to 2.35 GHz.
Performance - High End
The top model offers all the cores that are built into the chip and clocks relatively high at up to 5.4 GHz. Thanks to the improved IPC of the cores (especially the efficiency cores), the CPU should reach the level of the old Raptor Lake Core Core 9 270H (6 + 8 cores, max 5.8 / 4.1 GHz). This makes the CPU ideal for very demanding tasks such as high-end gaming and content creation.

► remove from comparisonThe Intel Core Ultra 7 265H is a mobile high-end CPU for larger notebooks based on the Arrow Lake architecture. It offers 16 cores consisting of 6 fast performance cores (Lion Cove) with up to 5.3 GHz and 8 smaller efficiency cores (Skymont) with up to 4.5 GHz clock speed and two additional "low power" efficiency cores with up to 2.5 GHz (Skymont).

The integrated GPU (iGPU) is an Intel Arc 140T graphics card which offers eight Xe cores with up to 2.3 GHz.
Performance - High End
Compared to the fastest model of the Arrow Lake-H series (Core Ultra 9 285H), the Core Ultra 7 as only slightly slower due to a reduced maximum Turbo frequency of 100 MHz. Thanks to the improved IPC of the cores (especially the efficiency cores), the CPU should reach the level of the old Raptor Lake Core Core 9 270H (6 + 8 cores, max 5.8 / 4.1 GHz). This makes the CPU ideal for very demanding tasks such as high-end gaming and content creation.
