Intel Core Ultra 9 275HX vs AMD Ryzen 9 9955HX3D

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. The base tile is manufactured by Intel in the 22nm process and carries the individual chiplets thanks to Fovero's 3D packaging.

AMD Ryzen 9 9955HX3D

► remove from comparison AMD R9 9955HX3D

The AMD Ryzen 9 9955HX3D is a high-end notebook processor of the Fire Range series with 16 cores and hyperthreading (SMT), which means it can process up to 32 threads simultaneously. The CPU uses the new Zen 5 architecture for all 16 cores and clocks them at 2.5 to 5.4 GHz (single-core boost). As a special feature, the HX3D has an additional 64M 3D V-Cache on a CCD. This means that the CPU offers combined 128 MB L3 cache and 16 MB L2 cache. The chip was presented at CES in early 2025 and is intended for fast and expensive gaming notebooks.

AMD claims that the Ryzen 9 9955HX3D is the fastest mobile gaming CPU. Based on the experience with its predecessor, the Ryzen 9 7945HX3D, this is quite realistic. The 3D V-Cache in particular can accelerate demanding 3D games. However, the 16 fast Zen 5 cores should also provide enough power for all possible demanding applications.

The 9955HX3D is intended for large and heavy gaming notebooks and can therefore draw quite an amount of power (configurable from 55- to 75 watts TDP, default 55 watts). The SoC consists out of three dies on a package where the processor dies are manufactured in the modern 4nm 4nm FinFET process at TSMC (I/O die in 6nm) and should therefore still have a good energy efficiency.
