Intel Core i5-1335U
A 15W Raptor Lake-U chip with two performance cores and eight efficiency cores, the mid-range refresh of the earlier Core i5-1235U. Clocks rise modestly for quicker single-thread response, but the same core layout still limits heavy multi-threaded workloads.
Pros
- Quick single-core response for everyday tasks and browsing
- Ten cores handle background multitasking comfortably
- 80-EU Iris Xe graphics ahead of entry-level iGPUs
- Supports LPDDR5-6400 and DDR5-5200 memory
- 15W base power suits thin, fanless laptop designs
Cons
- Only two performance cores limits heavy multi-core work
- Multi-core throughput trails 8-core Ryzen U chips
- Sustained clocks drop quickly in thin chassis
