CPU Comparison
Core i5-1334U vs Core i7-1355U
A side-by-side comparison of specs, performance and value. The Intel Core i5-1334U is a low-power mobile processor designed for everyday ultrabooks and thin-and-light laptops. Part of the Raptor Lake-U family, it features 10 cores (2 Performance + 8 Efficient) and 12 threads. Operating at a 15W base TDP, it prioritizes battery life and thermals. With a max turbo of 4.6 GHz and 12MB of L3 cache, it delivers snappy performance for daily tasks, web browsing, and office applications. The integrated Iris Xe Graphics with 80 Execution Units provides capable display handling and light media consumption. Released in early 2023, the 1334U targets students and professionals who need long battery life and basic productivity capability in a highly portable, fanless or single-fan chassis.
