There have been some recent reports from users observing performance issues when running VMware Workstation on Windows 11 along with using recent Intel (12th Gen and later) Hybrid CPUs, which introduces a new hybrid big.LITTLE architecture for Intel's x86 consumer CPUs.
This new Intel Hybrid CPU contains two types of CPU cores: Performance-cores (P-cores) and Efficiency-cores (E-cores) into the same physical CPU die, which follows a similar design to Apple Silicon CPUs. For information about the new Intel hybrid Intel CPUs, check out this resource HERE.
At first glance, most users had assumed this was due to Virtual Machines being scheduled to run on the less powerful E-Cores, this was problematic even for non-VMware use cases and with the recent introduction of Intel Thread Director, this was supposed to have been improved with Windows 11.
However, after some internal testing, the Intel Hybrid CPU may not actually be the culprit.
