Intel Core 7 245HX

The Intel Core 7 245HX is a fast mid-range mobile CPU for gaming notebooks based on the Arrow Lake architecture. It offers 20 cores consisting of 6 of the 8 fast performance cores with up to 5.1 GHz and 8 of the 16 smaller efficiency cores with up to 4.5 GHz clock speed. The CPU can access 24 MB L2 cache and 26 MB L3 cache and is specified with a TDP of 55 watts. Compared to the similar Core Ultra 5 245HX, the Core 7 245HX offers a slower P-core base speed, iGPU boost clock and does not support vPro management features.

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 DDR5-6400 (dual channel, ECC optional). The integrated GPU (iGPU) is a small graphics card called Intel Graphics, which offers three of the four Xe cores with 300 - 1900 MHz.

Performance - High End

Thanks to the improved IPC of the cores (especially the efficiency cores), the CPU should be just before or at the level of the Raptor Lake Core i9-14500HX (6 + 8 cores, max 5 / 3.5 GHz). This makes the CPU very suitable for demanding tasks such as high-end gaming (2024 games) and content creation. The CPU performance should be nearly identical to the older Core Ultra 5 245HX as the slower base speed of the P-cores wont matter much in typical loads.

Production - TSMC and Foveros

The Arrow Lake-HX chips are based on the desktop Arrow Lake-S chips and are composed of several chiplets. The CPU part is manufactured at TSMC in the modern N3B (3nm) process, the GPU also comes from TSMC in the N5P process. The SoC and I/O tile are manufactured in the TSMC N6 process. The base tile is manufactured by Intel in the 22nm process and carries the individual chiplets thanks to Fovero's 3D packaging.
