Intel Core Ultra 5 235HX vs Intel Core Ultra 9 275HX

Intel Core Ultra 5 235HX

► remove from comparison Intel Ultra 5 235HX

The Intel Core Ultra 5 235HX 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.

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 DDR5-6400 (dual channel, ECC optional). The integrated GPU (iGPU) is a small Intel Graphics graphics card with three of the four Xe cores running at 300 - 1800 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 performance difference to the Core Ultra 5 245HX is only slight, as the CPUs only differ in the base clock of the performance cores (2.9 vs 3.1 GHz).

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.

Intel Core Ultra 9 275HX

► remove from comparison Intel Ultra 9 275HX

The Intel Core Ultra 9 275HX is a mobile high-end CPU for gaming notebooks based on the Arrow Lake architecture. It offers 24 cores consisting of 8 fast performance cores with up to 5.4 GHz and 16 smaller efficiency cores with up to 4.6 GHz clock speed. The CPU has access to 40 MB L2 cache and 36 MB L3 cache and is specified with a TDP of 55 watts.

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 DDR5-6400 (dual channel, ECC optional). The integrated GPU (iGPU) is a small Intel Graphics graphics card with four Xe cores running at 300 - 1900 MHz.

Performance - High End

The performance of the Ultra 9 275HX is only slightly behind the top model, the Core Ultra 9 285HX, due to the 100 MHz lower boost clock of the P-cores Core Ultra 9 285HX and therefore also remains below the similar Desktop Core Ultra 9 285K (higher clocked with up to 5.7 GHz and more TDP with 125 watts). Due to the improved IPC of the cores (especially the efficiency cores), the CPU should perform just behind or at the level of the Raptor Lake Core i9-14900HX (8 + 16 cores, max 5.8 / 4.1 GHz). This makes the CPU ideal for very 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 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.
