GPU optimized virtual machine sizes

GPU optimized VM sizes are specialized virtual machines available with single, multiple, or fractional GPUs. These sizes are designed for compute-intensive, graphics-intensive, and visualization workloads. This article provides information about the number and type of GPUs, vCPUs, data disks, and NICs. Storage throughput and network bandwidth are also included for each size in this grouping.

  • NC-series, NCv2-series, NCv3-series and NCT4_v3-series sizes are optimized for compute-intensive and network-intensive applications and algorithms. Some examples are CUDA and OpenCL-based applications and simulations, AI, and Deep Learning. The NCT4v3-series is focused on inference workloads featuring NVIDIA's Tesla T4 GPU and AMD EPYC2 Rome processor. The NCv3-series is focused on high-performance computing workloads featuring NVIDIA’s Tesla V100 GPU. The NC-series uses the Intel Xeon E5-2690 v3 2.60GHz v3 (Haswell) processor, and the NCv2-series and NCv3-series VMs use the Intel Xeon E5-2690 v4 (Broadwell) processor.

  • ND-series, and NDv2-series sizes are focused on training and inference scenarios for deep learning. They use the NVIDIA Tesla P40 GPU and the Intel Xeon E5-2690 v4 (Broadwell) processor. The NDv2-series uses the Intel Xeon Platinum 8168 (Skylake) processor.

  • NV-series and NVv3-series sizes are optimized and designed for remote visualization, streaming, gaming, encoding, and VDI scenarios using frameworks such as OpenGL and DirectX. These VMs are backed by the NVIDIA Tesla M60 GPU.

  • NVv4-series VM sizes optimized and designed for VDI and remote visualization. With partitioned GPUs, NVv4 offers the right size for workloads requiring smaller GPU resources. These VMs are backed by the AMD Radeon Instinct MI25 GPU. NVv4 VMs currently support only Windows guest operating system.

Supported operating systems and drivers

To take advantage of the GPU capabilities of Azure N-series VMs, NVIDIA or AMD GPU drivers must be installed.

Deployment considerations

  • For availability of N-series VMs, see Products available by region.

  • N-series VMs can only be deployed in the Resource Manager deployment model.

  • N-series VMs differ in the type of Azure Storage they support for their disks. NC and NV VMs only support VM disks that are backed by Standard Disk Storage (HDD). NCv2, NCv3, ND, NDv2, and NVv2 VMs only support VM disks that are backed by Premium Disk Storage (SSD).

  • If you want to deploy more than a few N-series VMs, consider a pay-as-you-go subscription or other purchase options. If you're using an Azure free account, you can use only a limited number of Azure compute cores.

  • You might need to increase the cores quota (per region) in your Azure subscription, and increase the separate quota for NC, NCv2, NCv3, ND, NDv2, NV, or NVv2 cores. To request a quota increase, open an online customer support request at no charge. Default limits may vary depending on your subscription category.
