History
The Alder Lake-P series, launched in early 2022, represented Intel's ambitious restructuring of the mobile processor market. For years, the standard U-series (15W) and H-series (45W) dominated the landscape, leaving a gap for thin-and-light laptops that needed more power without extreme battery drain. Intel addressed this by introducing the P-series, a 28W line designed to bridge the gap.
The Core i5-1250P debuted as a prime example of this new strategy, offering 12 cores in a form factor traditionally reserved for 4-core chips. This launch was critical in Intel's response to AMD's efficient Ryzen 6000 mobile series. By utilizing the hybrid architecture from desktop Alder Lake, Intel managed to fit 12 cores into a 28W design, dramatically increasing multi-threaded performance for ultraportables.
The P-series effectively replaced older 28W Intel chips and offered a compelling alternative for users who found U-series too slow and H-series too bulky. The i5-1250P thus stands as a key product in Intel's 12th Gen mobile transition, redefining performance expectations for premium thin-and-light laptops.
Improvements over Previous Generation
- Massive increase in core count (4 to 12).
- Introduction of hybrid P-core and E-core architecture.
- Higher turbo power limit and DDR5 support.
