The six SKUs revealed include the 285HX, 275HX, 265HX, 255HX, 245HX, and 235HX. The flagship 285HX and its close relative, the 275HX, boast the most cores, featuring a formidable combination of eight performance (P) cores and sixteen efficiency (E) cores. This powerful combination allows these processors to seamlessly handle both demanding applications and lighter workloads. The key distinction between these two chips lies in their maximum turbo clock speeds. The 285HX reaches a blistering 5.5 GHz, while the 275HX sits just below at 5.4 GHz. The 275HX also experiences a slight reduction in base clock speed for P-cores, clocking in at 2.7 GHz compared to the 285HX's 2.8 GHz. Notably, both chips maintain identical E-core clock speeds.
Moving down the lineup, the 265HX and 255HX feature a slightly reduced core configuration with eight P-cores and twelve E-cores, resulting in four fewer E-cores compared to their high-end counterparts. Their maximum turbo frequencies also see a modest decrease, reaching 5.3 GHz for the 265HX and 5.2 GHz for the 255HX, respectively. The P-core base clocks for these two chips are 2.6 GHz for the 265HX and 2.4 GHz for the 255HX. The E-core clock speeds exhibit a similar pattern, with the 265HX offering a 4.6 GHz boost and a 2.3 GHz base, while the 255HX settles for a 4.5 GHz boost and a 1.8 GHz base.
At the lower end of the spectrum, the 245HX and 235HX distinguish themselves by having fewer P-cores than their predecessors. These chips feature six P-cores and eight E-cores, providing a balanced combination of performance and efficiency. Both chips share a maximum turbo clock of 5.1 GHz on the P-cores and 4.5 GHz on the E-cores. The differentiation between these two chips lies in their integrated graphics clock speeds and P-core base clocks. The 245HX boasts a higher P-core base clock of 3.1 GHz compared to the 235HX's 2.9 GHz. Both chips maintain the same E-core base clock of 2.6 GHz. However, these two SKUs lack support for Thermal Velocity Boost and Turbo Boost Max 3.0, potentially limiting their peak-rated boost frequencies.
The integrated graphics units also demonstrate variation across the six SKUs. The 285HX, 275HX, 265HX, and 255HX feature a larger iGPU equipped with 64 execution units (EUs) operating at a 1.9 GHz clock speed. The only exception is the flagship 285HX, which enjoys a 100 MHz boost to its iGPU, reaching a flat 2 GHz.
In contrast, the 245HX and 235HX are equipped with a noticeably smaller 48 EU iGPU compared to their higher-tier counterparts. The 245HX maintains the same 1.9 GHz operating GPU frequency as most of the other chips, but the 235HX experiences a 100 MHz reduction in clock speed, dropping to 1.8 GHz.
These upcoming Arrow Lake-HX chips demonstrate Intel's commitment to providing high-performance mobile processors that cater to demanding users. The increased core counts, enhanced clock speeds, and support for key technologies like HyperThreading set these processors apart from their predecessors. While Lunar Lake prioritizes efficiency, Arrow Lake-HX is clearly focused on pushing the boundaries of mobile performance, potentially challenging the dominance of AMD's Ryzen 7000 series.
The upcoming Arrow Lake-HX series holds great promise for the mobile computing landscape. With its powerful combination of cores, impressive clock speeds, and advanced features, this series is poised to deliver a compelling performance experience for users seeking the ultimate in mobile computing power. The release of these processors will be closely watched by industry experts and users alike, as they represent a significant step forward in the evolution of mobile computing.
