Intel Core Ultra 9 285HX vs AMD Ryzen 9 9955HX

Intel Core Ultra 9 285HX

► remove from comparison Intel Ultra 9 285HX

The Intel Core Ultra 9 285HX 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 5.5 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 Enterprise. 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 - 2000 MHz.

Performance - High End

The performance of the Ultra 9 285HX should be slightly below the similar Desktop Core Ultra 9 285K (higher clocked with up to 5.7 GHz and more TDP with 125 watts). Thanks to the improved IPC of the cores (especially the efficiency cores), the CPU should outperform the old 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 9955HX

► remove from comparison AMD R9 9955HX

The AMD Ryzen 9 9955HX is a high-end notebook processor from the Fire Range series with 16 cores and hyperthreading (SMT), which means it can process up to 32 threads simultaneously. Unlike the Ryzen 9 9955HX3D, the chip does not offer a 3D V-Cache. The chip was presented at CES in early 2025 and is intended for fast and expensive gaming laptops.

Thanks to the high-clocked 16 Zen 5 cores, the performance of the CPU should be excellent and only be outperformed by the 9955HX3D thanks to the 3D V-Cache. Together with the Intel Core Ultra 9 285HX at the top of the mobile CPUs.

The 9955HX is intended for large and heavy gaming notebooks and is therefore configurable from 55-75 watts TDP (default 55 watts). The SoC is manufactured in the modern 4nm FinFET process at TSMC (both compute dies, I/O die in 6nm) and should therefore have very good energy efficiency.
