Turbo Boost on Azure VM Bseries

Question

Hello,

I was wondering if Turbo Boost was enabled on the Bseries Azure VM ?

I saw there that it was enabled by default on the Dseries.enabling-turbo-boost-on-d-series-servers

I was looking at this thread banked-credits-on-bseries-vm-questions-2018 regarding Turbo Boost on Azure VM. It referred to this specs webpage sizes-b-series-burstable but with no mention of Turbo Boost on it, whereas it is clearly mentioned for the Dseries there dv3-dsv3-series .

Thanks in advance

Hello @Tristan ,

Thank you for reaching out to the Microsoft Q&A platform. Happy to answer your question.

That's correct. Turbo boost is enabled by default on the D-series which is not enabled for B-series. To add more, "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.

As far as I know, the processor on the B-series, does not include that technology and It is not something you yourself can enable or disable.

Hope this helps.

Thank you for your answer !

To sum up, Turbo Boost is available on the processors List_of_Intel_Xeon_processors_(Ice_Lake-based) of the B-series but disabled on Azure, and the user can not enable them as it is at the Bios level.
