The Intel Core i7-1260P is a 12-core mobile processor built on the Alder Lake architecture, designed for thin-and-light laptops requiring a balance of performance and battery life.
The Core i7-1260P represents the entry point for Intel's 12th Gen P-series mobile lineup. Featuring a 4P+8E core configuration, it provides 12 cores and 16 threads. With a base 28W TDP that can boost up to 64W, it fits perfectly into premium ultrabooks needing sustained performance.
The integrated Iris Xe 96EU graphics handle everyday multimedia and light gaming efficiently.
Specifications
Performance
Excels at multitasking, heavy office workloads, and web browsing with dozens of tabs open.
Capable of running local virtual machines for development purposes, though limited by memory bandwidth.
Handles esports titles and older games at 1080p well, but struggles with demanding AAA titles without a discrete GPU.
The E-cores provide excellent idle and low-load efficiency, extending battery life significantly.
- •Relies on Iris Xe 96EU integrated graphics
- •Suitable for Minecraft, CS:GO, and League of Legends
- •Not recommended for modern AAA gaming without discrete GPU
- •Uses CPU-based inference for AI workloads
- •Lacks a dedicated NPU found in later Meteor Lake generations

History
The Core i7-1260P launched in early 2022 as a critical component of Intel's 12th Gen mobile strategy. It represented a shift from the traditional monolithic core design to a hybrid approach. Aimed directly at the premium ultrabook market, it allowed manufacturers to build devices that could sustain heavy workloads without requiring the large batteries and coolers of full H-series gaming laptops.
This chip successfully bridged the gap for power users on the go.</br>The release of this processor coincided with Intel's broader push to reclaim performance leadership in the mobile sector. By introducing the P-series designation, Intel clearly separated their high-efficiency U-series from their high-performance H-series, giving OEMs a perfect 28W middle ground.
The 1260P specifically served as the value-entry to this new tier, offering nearly the same capabilities as the top-tier 1280P but at a more accessible price point for business and premium consumer laptops.
Improvements over Previous Generation
- Addition of 8 E-cores vastly increasing multi-thread performance
- Transition to hybrid architecture
- Support for DDR5 memory
