Intel's Arrow Lake-based Core Ultra 7 255H appears to have been tested in PassMark, where it outperformed its Meteor Lake equivalent by 32% in single-threaded tests (via x86deadandback at X). Across a wide variety of metrics, the 255H is roughly 15% faster in CPU Mark, which is PassMark's proprietary metric for gauging a CPU's performance.
Intel revealed its Arrow Lake-H family of processors at CES, shortly followed by a user review at Bilibili, which left much to be desired from these CPUs. Dubbed Core Ultra 200H, these processors employ Intel's Arrow Lake architecture featuring Lion Cove P-cores and Skymont E-cores. What separates them from desktop chips, apart from the power envelope, is that these CPUs feature an LPE (Low Power Efficient) core cluster on the SoC Tile, a feature reused from Meteor Lake.
