Intel Core Ultra 7 270HX Plus

The Intel Core Ultra 7 270HX Plus is a mobile high-end CPU for gaming notebooks based on the Arrow Lake architecture. It offers 20 cores consisting of 8 fast performance cores with 2.4 to 5.3 GHz and 12 of the 16 smaller efficiency cores with 1.8 to 4.7 GHz clock speed. The CPU can access 36 MB L2 cache and 36 MB L3 cache and is specified with a TDP of 55 watts. An improvement of the Plus-Refresh is a faster die-to-die frequency (+900 MHz).

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 256 GB dual channel DDR5-6400 (ECC not supported). The integrated GPU (iGPU) is a small Intel Graphics graphics card with four Xe cores running at 300 - 1900 MHz.

Performance - High End

Due to the only minimally changed clock rates (most importantly the +100 MHz boost of the efficiency cores), the Core Ultra 7 270HX Plus is only slightly ahead of the old Ultra 7 265HX. This makes the CPU ideal for demanding tasks such as high-end gaming and content creation.

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 using 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.
