Performance Hybrid Architecture

Recently, Intel introduced the 12th generation Intel® Core™ processor family, formerly code named Alder Lake. These processors are unique because they are the first PC processor family based on a new performance hybrid architecture. This CPU architecture leverages two distinct types of cores: Performance-cores and Efficient-cores. This multicore solution is optimized for many workload types: single-threaded and partially threaded, as well as multithreaded applications.



Introduction to Performance Hybrid Architecture for 12th Generation Intel® Core™ Processors 

The first in a series of white papers, this document provides an overview of the performance hybrid architecture and the motivation behind it. It continues with Instruction Set Architecture and operating system support and introduces Intel® Thread Director technology.
