@Nguyễn Hữu Tùng Apologies for the delay in response and all the inconvenience caused because of the issue.
As mentioned here by our internal team member :
Turbo Boost is an internal implementation and is triggered automatically as needed by the underlying host infrastructure and there is no way to control it or monitor it by customer. This is controlled at the Bios level and you do not have any access to this level of hardware.
Although the processor does include that technology it is not something you yourself can enable or disable.
You are allocated the number of processors you pay for when you pick your size but besides that there is no additional options to enable turbo boost technology. As mentioned, this series of processor can be better for applications that require faster CPUs but this is already configured by Azure. There is no additional action required from you to be able to utilize this technology.
Hope it helps!!!
