Intel Core Ultra 7 255U

The Intel Core Ultra 7 255U is a 12-core mobile processor released in January 2025, based on the Arrow Lake microarchitecture.

The Intel Core Ultra 7 255U is a mobile processor from Intel's Arrow Lake family, launched in January 2025. It features 12 cores (2 performance cores and 8 efficient cores) with 14 threads, a base clock of 2.0 GHz, and a boost clock of up to 5.2 GHz. The processor includes 12 MB of L3 cache and is built on a 3 nm process node. It has a base power of 15 W and a maximum turbo power of 57 W, making it suitable for thin-and-light laptops. The CPU supports up to LPDDR5/X 8400 MT/s or DDR5 6400 MT/s memory across two channels, but does not support ECC memory. It integrates Intel Graphics and provides 20 PCIe 4.0 lanes. The processor uses the FCBGA2049 socket and supports instruction sets including SSE4.1, SSE4.2, and AVX2. The multiplier is locked, preventing overclocking.
