Intel Core i7-14700HX vs Intel Core Ultra 7 255H

Intel Core i7-14700HX

► remove from comparison Intel i7-14700HX

The Intel Core i7-14700HX is a high-end CPU based on the new Raptor Lake architecture for large and heavy notebooks. The CPU was introduced at the beginning of 2024 as part of the Raptor Lake HX refresh. The i7-14700HX is similar to the Core i7-13850HX with slightly higher clocked CPU cores.

The total of 28 threads are divided into P-cores and E-cores, which we already know from Alder Lake. The 14700HX offers 8 performance cores (P-cores) with hyperthreading and 12 efficiency cores (E-cores) without hyperthreading. A total of 28 threads are therefore supported. The P-cores clock at up to 5.5 GHz (single core) and the E-cores up to 3.9 GHz. The integrated memory controller supports a maximum of DDR5 with 5600 MHz.

Compared to Alder Lake, the new Raptor Lake architecture offers improved P-cores (Raptor Cove architecture with more cache), more E-cores (same Gracemont architecture) and higher clock rates thanks to the improved Intel 7 process. Furthermore, Intel now supports faster DDR5 main memory (up to 5600 MHz) in the top models.

The 14700HX is manufactured on the older 10nm FinFET process at Intel (Intel 7 process) and is specified with 55 watts base power and 157 watts turbo power.

Intel Core Ultra 7 255H

► remove from comparison Intel Ultra 7 255H

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.
