GPU Memory of Standard_NC16as_T4_V3

Hello Everyone

I am researching a solution for Azure Virtual Machines that can run Siemens NX and I came across this article: https://learn.microsoft.com/en-us/azure/architecture/guide/hpc/siemens-nx

They recommend three Virtual machines, and the Standard_NC16as_T4_V3 seemed the best solution for me, so I looked up the device's specification, which say that the device has 2GB of GPU Memory: https://learn.microsoft.com/en-us/azure/virtual-machines/nct4-v3-series

But they also state that the GPU's have 16GB of Memory just above it:

The NCasT4_v3-series virtual machines are powered by Nvidia Tesla T4 GPUs and AMD EPYC 7V12(Rome) CPUs. The VMs feature up to 4 NVIDIA T4 GPUs with 16 GB of memory each

So which one of these specifications are true? Or is it up to 16 GB of memory?

Thank you for your help.

Kind regards,

Gabriel

    Where does it say 2GB GPU? I can't see this anywhere. It is 16GB of GPU for the NC16as_T4__v3 size.

    Can you provide a screen capture for where you are seeing 2GB?

    Hello @Bühler Gabriel

    Based on the information provided in the article and the Azure documentation, it appears that the Standard_NC16as_T4_V3 virtual machine has 4 NVIDIA T4 GPUs, each with 16 GB of memory, for a total of 64 GB of GPU memory.

    The statement you made about the device having 2 GB of GPU memory may be a mistake or a typo. The correct information is the one mentioned in the same paragraph, which states that the VMs feature up to 4 NVIDIA T4 GPUs with 16 GB of memory each.

    I would recommend referring to the Azure documentation for the most accurate and up-to-date information on the specifications of the Standard_NC16as_T4_V3 virtual machine.
    According to the documentation, the NCasT4_v3-series virtual machines are powered by Nvidia Tesla T4 GPUs and feature up to 4 NVIDIA T4 GPUs with 16 GB of memory each. Therefore, the total GPU memory for the Standard_NC16as_T4_V3 virtual machine is up to 64 GB.
