Thank you for posting in the Intel Community.
I recommend confirming if the Intel® Hyper-Threading feature is enabled on the system BIOS, make sure that you have the system BIOS up to date (we recommend taking this actions with the guidance of the Original Equipment Manufacturer).
You can also make sure that your operating system is set up to work in high performance (if your system is a laptop please set high performance for both plug and on battery settings), this setting can be found on:
1- Windows setting.
3- Power and sleep.
4- Additional power settings
Hope this helps.
