Performance Tuning Games for Hybrid Architectures | GDC 2022 | Intel Software
9Get an overview of 12th generation Intel® Core™ processors (formerly code named Alder Lake), the differences between P-cores and E-cores, and how to leverage each of these cores to your advantage in games. We cover some of the basics, performance characteristics, thread scheduling, Intel® Thread Director, CPUID and MSR changes, and discuss some of the game subsystems that we think are particularly well suited for E-cores.
