The Intel Core Ultra 9 275HX is a 2025 mobile processor with 24 cores (8 P-cores, 16 E-cores) and 24 threads, based on the Arrow Lake microarchitecture.
The Intel Core Ultra 9 275HX is a high-end mobile processor released in January 2025. It features 24 cores (8 performance cores and 16 efficient cores) and 24 threads, with a base clock of 2.7 GHz and a boost clock of 5.4 GHz. The processor is built on a 3 nm process node and has a total L2 cache of 40 MB and an L3 cache of 36 MB. It supports up to DDR5 6400 MT/s memory across two channels and does not support ECC memory. The CPU has a base power of 55 W and a maximum turbo power of 160 W. It includes integrated Intel Arc graphics with 4 Xe-cores. The processor uses the FCBGA2114 socket and provides 24 PCIe lanes (version 5.0 and 4.0). It supports 64-bit instructions, Intel SSE4.1, SSE4.2, and AVX2. The multiplier is locked. This processor is designed for high-performance laptops and mobile workstations.
