Verdict

The Intel Core i7-1355U is a 13th Gen 'Raptor Lake-U' mobile processor featuring 10 cores (2 Performance-cores at 1.7–5.0 GHz and 8 Efficient-cores at 1.2–3.7 GHz) and 12 threads with a 12MB L3 cache. Its main strengths include a low 15W base power (max 55W) for excellent energy efficiency in thin-and-light laptops, support for modern LPDDR5-6400 memory, and capable integrated Intel Iris Xe graphics with 96 execution units. However, its low TDP limits sustained performance during heavy workloads like 4K video editing, and it offers only minor performance gains over its predecessor, the i7-1255U.
