Intel Arrow Lake-HX Core Ultra 9 275HX Leaks on Geekbench: 24-Core, 24-Thread CPU with 5.3 GHz Boost Clock

The highly anticipated Intel Core Ultra 9 275HX mobile CPU from the Arrow Lake-HX series has recently emerged on Geekbench, offering insights into its capabilities and performance potential.

Key Specifications of the Intel Core Ultra 9 275HX

Following the release of the Arrow Lake desktop processors, Intel is now developing mobile variants, with an expected launch in early 2025. The Arrow Lake mobile lineup includes the Core Ultra 200H and Core Ultra 200HX series. While there have been multiple leaks concerning the former, information regarding the 200HX CPUs has been comparatively sparse.

Benchmark tests indicate that the Core Ultra 9 275HX is designed to cater to high-performance gaming laptops. Notably, the Razer Blade 18 gaming laptop featured in the Geekbench test yielded data primarily related to the GeForce RTX 4090 GPU used in its OpenCL performance, with no direct scores disclosed for the CPU. However, the System Information page revealed crucial specifications of the CPU.

The Intel Core Ultra 9 275HX is positioned as one of the high-end models in the Ultra 200HX family, just below the flagship Core Ultra 9 285HX. It features a total of 24 cores, organized into dual clusters consisting of 8 Performance and 16 Efficient Cores.

Notably, the Arrow Lake architecture does not support hyperthreading, resulting in a configuration of 24 cores and 24 threads. The Core Ultra 9 275HX has a base clock speed of 2.7 GHz and can boost up to 5.3 GHz (exactly 5286 MHz), slightly lower than the Core Ultra 9 285HX’s maximum boost capability.

With the Core Ultra 9 285HX expected to achieve a boost frequency of up to 5.5 GHz, both CPUs share similar specifications, including a 36 MB L3 cache. The thermal design power (TDP) specifics remain undisclosed in this benchmark data, but integrated graphics based on the Xe-LPG architecture are confirmed, comprising 64 execution units (EUs) and running at 2000 MHz.

These high-end CPUs are poised to be paired with powerful discrete GPUs, exemplified by the performance of the NVIDIA GeForce RTX 4090 highlighted in the benchmark. Anticipation is building as Intel prepares to unveil its Arrow Lake-HX series at CES 2025, taking place on January 6.
