Intel Arrow Lake-HX CPUs Leak: Core Ultra 9 285HX to Feature 24 Cores, Set for Q4 2024 Launch

Details about Intel’s upcoming Arrow Lake-HX enthusiast CPU family have surfaced, showcasing the Core Ultra 9 285HX as the flagship model featuring up to 24 cores. Intel’s next-gen “HX” laptop lineup will be built around the company’s new Core Ultra 200 processor, which shares the same die design as its desktop counterparts and includes at least six SKUs according to recent information shared by @jaykihn0.

Leaks About the Intel Arrow Lake-HX CPUs

The Arrow Lake-HX CPU lineup will feature the Intel Core Ultra 9 285HX, Core Ultra 9 275HX, Core Ultra 7 265HX, and Core Ultra 7 255HXS as well as the only listed U / ULT variant which is the six core/12 thread Intel Core Ultra-5 i5-U225HX and quad-core/eight-thread part (Core Quad-Core Turbo Processor). There will be more than one configuration for each SKU, almost all centered on clock frequencies.

First-up is Core Ultra 9 285HX, the flagship of the family which includes 8 P-Cores with Lion Cove architecture along with 16 E-Cores with Skymont design, a total of 24 cores and threads. It boasts a ground clock of 2.8 GHz for the P-Cores along with 2.1 GHz for the E-Cores and also an optimal turbo clock of 5.5 GHz for the P-Cores and 4.6 GHz for the E-Cores. P-Cores can boost up to 5.2 GHz, all-core, and there is an integrated GPU with 64 EUs ticking at 2.0 GHz as well. The next Core Ultra 9 275HX will feature the same specs but come with P-Cores that are up to 100 MHz slower in terms of boost clocks.

Next is the Core Ultra 7 265HX, which features 8 P-cores and 12 E-cores for a total of 20 cores and 20 threads. It operates at a base frequency of 2.6 GHz for the P-Cores and 2.3 GHz for the E-Cores, with maximum boost clocks of 5.3 GHz and 4.6 GHz, respectively. The maximum all-core boost for the P-Cores is 5.1 GHz. The Core Ultra 7 255HX will have 100 MHz lower boost clocks for both core types.

Finally, the Core Ultra 5 245HX will provide a configuration of 6 P-cores and 8 E-cores, resulting in 14 cores and 14 threads. This CPU will run at a base frequency of 3.1 GHz for the P-Cores and 2.6 GHz for the E-Cores, with maximum boost clocks of 5.1 GHz and 4.5 GHz. The maximum all-core boost clock is set at 5.0 GHz, while the Core Ultra 5 235HX will feature a similar core configuration but a reduced base frequency of 2.9 GHz for the P-Cores.

Intel has indicated that the Arrow Lake CPUs, which will be available for both desktops and laptops, are on schedule for a Q4 2024 launch. The first Arrow Lake desktop family is expected to be unveiled next month, with the Arrow Lake-HX “Core Ultra 200” lineup likely to be announced around the same time, possibly at CES in early 2025. This new lineup will compete with AMD’s Fire Range (HX) SKUs and will be paired with NVIDIA’s next-gen RTX 50 GPUs.
