Intel Core i9-14900HX vs Intel Core Ultra 7 255HX

Intel Core i9-14900HX

► remove from comparison Intel i9-14900HX

The Intel Core i9-14900HX is a high-end CPU based on the Raptor Lake architecture for large and heavy notebooks. The CPU was introduced at the beginning of 2024 and is a slightly higher clocked variant of the older Core i9-13980HX.

The total of 32 threads are divided into P-cores and E-cores, which we already know from Alder-Lake. Here, 8 performance cores (P-cores) with hyperthreading are used and 16 efficiency cores, so that a total of 32 threads can be processed simultaneously. The P-cores clock from 2.2 GHz (base clock) to 5.8 GHz (single-core turbo) and the E-cores from 1.6 GHz to 4.1 GHz.

Performance

Due to the slightly higher maximum clock rates, the single-core performance of the 14900HX in particular increases slightly compared to the 13980HX. Compared to AMD's top model, the Ryzen 9 7945HX or 7945HX3D the 14900HX comes in just behind (on average in our benchmarks). However, the performance depends on the benchmark and the cooling and is usually very comparable.

Graphics

Like the Intel Core i9-12900HX, the Intel Core i9-14900HX offers an integrated graphics unit. The Intel Iris XE architecture continues to serve as the basis. In terms of performance, however, not much has changed with the Intel UHD Graphics 770.

The 14900HX is manufactured on the improved 10nm FinFET process at Intel (Intel 7 process) and is specified with 55 watts of base power and 157 watts of turbo power.

Intel Core Ultra 7 255HX

► remove from comparison Intel Ultra 7 255HX

The Intel Core Ultra 7 255HX 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 up to 5.2 GHz and 12 of the 16 smaller efficiency cores with up to 4.5 GHz clock speed. The CPU has access to 30 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 - 1850 MHz.

Performance - High End

Thanks 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 i9-14700HX (8 + 12 cores, max 5.5 / 3.9 GHz). 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 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.
