History
The Core i5-1345U was introduced in early 2023 as part of Intel's 13th Gen Raptor Lake mobile lineup. It arrived during a critical time when laptop manufacturers were demanding more performance within the same 15W power envelope. By adding more E-cores and bumping up the turbo frequencies compared to its Alder Lake predecessor, Intel managed to provide a tangible generation-over-generation improvement.
This processor helped bridge the gap between basic office tasks and heavy multitasking, allowing ultrabooks to handle more aggressive workloads without sacrificing the thin-and-light form factors that consumers preferred.
Improvements over Previous Generation
- Higher boost clock
- Faster memory support
- Refined E-core cluster
