Microsoft Azure – NVadsA10 v5-series

Microsoft have released a new instance powered by NVIDIA A10 GPUs and AMD EPYC 74F3V(Milan) CPU with a base frequency of 3.2 Ghz, all cores peak frequency of 4.0Ghz.  With NVadsA10v5-series Azure is introducing virtual machines with partial NVIDIA GPUs. Pick the right sized virtual machine for GPU accelerated graphics applications and virtual desktops starting at 1/6th of a GPU with 4-GiB frame buffer to a full A10 GPU with 24-GiB frame buffer.

The preview is currenty availabe in Azure – US South Central and Azure – West Europe regions.

Prices are now GA (21th March 2022) for North Europe, US East 2, US West3

Sign up for preview to get early access to the NVadsA10v5-series.

NVIDIA Ampere GPU (A10) is supporting GPU-P (SR-IOV) which is why its a big step for partitioning the GPU and making the price dramatically cheaper in Azure. *note there have not been released any prices yet of the instances (its unknown)

Findings Video conference with Azure Virtual Desktop using Zoom





Over the last couple of years, there has been an impressive flux with many businesses and institutions adopting and relying on large-scale remote working and remote learning environments to maintain workforce and learning continuity. During this time, it’s generally been recognised that this type of remote working/learning has been quite successful, with many businesses and institutions continuing remoting working/learning practices or introducing hybrid models with a combination of remote and office work for their staff. 

One of the reasons why remote working/learning has been successful is the availability of supporting technologies that have delivered a high standard of human communication and engagement across large numbers of workers or students/faculty in remote environments. Video conferencing applications, which includes video conferencing, screen sharing, IMs and more, are such technologies that have contributed to viable remote working/learning environment success.  

But to use these applications to their fullest potential, a robust IT infrastructure is also a must. Many large enterprise companies, as well as SMB and other institutions have centralised their IT environment into virtualized desktop infrastructure (VDI), either as an on-premises solution or as a managed-service by cloud service providers (CSP). Centralizing resources, applications and data into a single infrastructure allows for better IT management and security of vital resources and data which can help improve workforce productivity, data security and IT efficiencies.

Investigation overview

This blog details a recent technical investigation where popular video conferencing applications are deployed on AMD-based Azure instances to determine the performance of each application, the number of deployable users in a multi-session environment, and the user experience each person would receive. The AMD-based instances includes both CPU-only based instances and CPU+GPU based instances to understand the impact of GPU-enabled resources to the density and experience of the users.

So next let’s look at the various parameters for the investigation.
