Intel Core i7-1255U vs Apple M2

Last updated:
Introduction and Technical Foundations The Apple M2 is a System-on-a-Chip (SoC) developed by Apple for Mac systems and iPads, designed for deep hardware and software integration.

It is manufactured using a 5nm process and features an 8-core CPU with performance and efficiency cores, as well as a 10-core graphics unit. The Intel Core i7-1255U is a 12th generation Intel processor (Alder Lake U) for thin notebooks in the Windows market.

It is manufactured using a 10nm process and utilizes a hybrid architecture with ten cores (two performance, eight efficiency cores) and twelve threads. Performance, Gaming, and Energy Efficiency In single-core performance, the Apple M2 significantly outperforms the Intel Core i7-1255U.

In multi-core performance, the Apple M2 is more powerful in Geekbench 6, while the Intel Core i7-1255U shows slight advantages in Cinebench R23. The integrated Apple M2 (10 Core) graphics delivers stronger performance for games and creative applications than the Intel Iris Xe Graphics 96 (Alder Lake).

The Apple M2's 5nm manufacturing process ensures excellent energy efficiency and long battery life, a level the Intel Core i7-1255U usually does not achieve. The Apple M2 also offers higher maximum memory bandwidth. Price-Performance and Recommendation A direct price-performance evaluation is complex because the Apple M2 is available as an integral part of Apple devices.

The Intel Core i7-1255U is available in many Windows devices across different price ranges.
