How does the OS/hardware decide how to schedule tasks to P or E cores?
- tedunangst 3y agoAMD used to have one core identified as "best" that could boost a little higher.
- tibbydudeza 3y ago"Intel’s Thread Director controller puts an embedded microcontroller inside the processor such that it can monitor what each thread is doing and what it needs out of its performance metrics. It will look at the ratio of loads, stores, branches, average memory access times, patterns, and types of instructions. It then provides suggested hints back to the Windows 11 OS scheduler about what the thread is doing, whether it is important or not, and it is up to the OS scheduler to combine that with other information about the system as to where that thread should go." Don't think AMD has such a thing consider their all cores are "equal" approach.
