AWS servers m6i vs. m7i family

0

Hello all

In our case, we upgraded our Windows servers from the m6i family to the m7i family.

The AWS documentation states that the m7i family has an Intel Xeon Scalable (Sapphire Rapids) CPU with a clock speed of 3.2GHz:

My question is, why does this CPU actually have a clock speed of only 2.4GHz?

Thanks for your answer and best regards

Sascha

Do you have the processor under load to cause it to scale to the turbo frequency?

Powered by 4th Generation Intel Xeon Scalable processors

M7i-flex and M7i instances are powered by custom 4th Generation Intel Xeon Scalable processors with an all-core turbo frequency of 3.2 GHz (max core turbo frequency of 3.8 GHz). These custom processors are only available on AWS and offer the best performance among comparable Intel processors. Both instances include support for always-on memory encryption using Intel Total Memory Encryption (TME).

I see it in the Windows Task Manager and in the CPU-Z tool.

The M7i[1] EC2 instance types supports CPU Clock Frequency of upto 3.2 GHz.

Features:

Up to 3.2 GHz 4th Generation Intel Xeon Scalable processor (Sapphire Rapids 8488C) The Windows Task Manager does not show the Turbo Frequency on the Nitro Based EC2 instances. You can get information about Turbo Frequency using third party tools such as HWInfo[1].

This issue doesn’t limit the instance from using the Turbo Frequency.
