Intel “Arrow Lake-HX” Leaks: Up to 24 Cores and 5.5 GHz in Laptop Form

While the upcoming desktop versions of Intel’s “Arrow Lake” processors are stealing all the hype, we are getting a leak about the high-performance “Arrow Lake-HX” chips for laptop space. Thanks to Jaykihn on X, we learn that Intel has prepared six SKUs for laptop enthusiasts to power workstations and gaming. The upcoming Core Ultra 200 series SKUs are 285HX, 275HX, 265HX, 255HX, 245HX, and 235HX. Starting with the lower-end Core Ultra Core Ultra 5 245HX / 235HX, we get six P-cores running at 3.1 and 2.9 GHz base speeds, respectively. For both SKUs, E-cores are clocked at 2.6 GHz at the base. Boosing the P-cores yields a maximum of 5.1 GHz, while E-cores top out at 4.5 GHz. For graphics, the 48 EUs inside the iGPU are clocked at 1.8 GHz on the 235 HX, while 245 HX runs at 1.9 GHz. THese models don’t support Thermal Velocity Boost and Turbo Boost Max 3.0, while of the remaining SKUs support both features.

Moving to the middle of the stack, there are two SKUs: Core Ultra 7 265HX / 255HX. Both feature eight P-cores and twelve E-cores. The differentiator here is the clock speed. P-cores on the 255HX run at 2.4 GHz base and 5.2 GHz boost, while the P-cores on 265HX run at 2.6 GHz base and 5.3 GHz boost. E-cores have a wider gap with the 255HX running at 1.8 GHz base and 4.5 GHz boost, while 265HX has E-cores pinned at 2.3 GHz base and 4.6 GHz boost. Both of these SKUs have iGPU with 64 EUs set at 1.9 GHz.

For the highest-end part, we have Core Ultra 9 275HX and 285HX CPUs. These SKUs come with eight P-cores and sixteen E-cores. The “weaker” 275HX CPU has P-cores clocked at 2.7 GHz base and 5.4 GHz boost, while the flagship 285HX SKU has P-cores at 2.8 GHz base and 5.5 GHz boost. E-cores run at 2.1 GHz at the base, with a 4.6 GHz boost on both SKUs. The graphics output capability is similar, with both SKUs rocking 64 EUs at 1.9 GH and 2.0 GHz for 275HX and 285HX.
