The P-cores in the 245HX and 235HX operate at base frequencies of 3.1 GHz and 2.9 GHz, respectively, while the E-cores run at a base speed of 2.6 GHz. These processors can boost the P-cores up to 5.1 GHz and the E-cores up to 4.5 GHz. Integrated graphics units (iGPU) feature 48 Execution Units (EUs), clocked at 1.8 GHz for the 235HX and 1.9 GHz for the 245HX. Notably, these lower-tier SKUs do not support Intel’s Thermal Velocity Boost or Turbo Boost Max 3.0 technologies, which are available in the higher-end models.
In the mid-range segment, Intel offers the Core Ultra 7 265HX and 255HX SKUs. Both models are configured with eight P-cores and twelve E-cores, providing a balanced mix of performance and efficiency. The Core Ultra 255HX operates with P-cores at a base frequency of 2.4 GHz and can boost up to 5.2 GHz, whereas the 265HX variant slightly increases the P-core base frequency to 2.6 GHz and the boost frequency to 5.3 GHz. The E-cores in the 255HX run at a base speed of 1.8 GHz and can boost to 4.5 GHz, while the 265HX E-cores are clocked at 2.3 GHz base and 4.6 GHz boost speeds. Both SKUs feature an integrated GPU with 64 EUs operating at 1.9 GHz, ensuring adequate graphics performance for demanding applications and gaming scenarios. These mid-tier processors support both Thermal Velocity Boost and Turbo Boost Max 3.0, enhancing their performance capabilities under optimal thermal conditions.
At the top of the lineup are the Core Ultra 9 275HX and 285HX processors, which cater to the most demanding laptop applications. These high-end SKUs incorporate eight P-cores and sixteen E-cores, delivering robust multitasking and processing power suitable for advanced workstations and high-performance gaming laptops. The Core Ultra 275HX has P-cores running at a base frequency of 2.7 GHz with a maximum boost of 5.4 GHz, while the flagship 285HX variant offers a slightly higher P-core base frequency of 2.8 GHz and a boost speed of 5.5 GHz. Both models’ E-cores are clocked at a base speed of 2.1 GHz, with a boost capability of 4.6 GHz. The integrated GPUs in these processors maintain a consistent performance level, featuring 64 EUs clocked at 1.9 GHz for the 275HX and 2.0 GHz for the 285HX. These top-tier CPUs support both Thermal Velocity Boost and Turbo Boost Max 3.0, allowing for sustained high performance during intensive tasks. Overall, Intel’s Arrow Lake-HX series for laptops aims to deliver a range of options tailored to different performance needs, ensuring that users can select a processor that aligns with their specific workload and usage scenarios.
