NGads V620-series
The NGads V620 series are GPU-enabled virtual machines with CPU, memory resources and storage resources balanced to generate and stream high quality graphics for a high performance, interactive gaming experience hosted in Azure. They're powered by AMD Radeon(tm) PRO V620 GPU and AMD EPYC 7763 (Milan) CPUs. The AMD Radeon PRO V620 GPUs have a maximum frame buffer of 32 GB, which can be divided up to four ways through hardware partitioning. The AMD EPYC CPUs have a base clock speed of 2.45 GHz and a boost1 speed of 3.5Ghz. VMs are assigned full cores instead of threads, enabling full access to AMD’s powerful “Zen 3” cores.
(1 EPYC-018: Max boost for AMD EPYC processors is the maximum frequency achievable by any single core on the processor under normal operating conditions for server systems.)
NGads instances come in four sizes, allowing customers to right-size their gaming environments for the performance and cost that best fits their business needs. The NG-series virtual machines feature partial GPUs to enable you to pick the right-sized virtual machine for GPU accelerated graphics applications and virtual desktops. The vm sizes start with 1/4 of a GPU with 8-GiB frame buffer up to a full GPU with 32-GiB frame buffer. The NGads VMs also feature Direct Disk NVMe ranging from 1 to 4x 960 GB disks per VM.

1 Physical Cores.
2 The actual GPU VRAM reported in the operating system will be little less due to Error Correcting Code (ECC) support.
3 Local NVMe disks are ephemeral. Data is lost on these disks if you stop/deallocate your VM. Local NVMe disks aren't encrypted by Azure Storage encryption, even if you enable encryption at host.
Supported operating systems and drivers
The NGads V620 Series VMs support a new AMD Cloud Software driver that comes in two editions: A Gaming driver with regular updates to support the latest titles, and a Professional driver for accelerated Virtual Desktop environments, with Radeon PRO optimizations to support high-end workstation applications.
To take advantage of the GPU capabilities of Azure NGads V620 Series VMs, AMD GPU drivers must be installed. NG virtual machines currently support only Windows guest operating systems.
To install AMD GPU drivers manually, see N-series AMD GPU driver setup for Windows for supported operating systems, drivers, installation, and verification steps.
Size table definitions
Storage capacity is shown in units of GiB or 1024^3 bytes. When you compare disks measured in GB (1000^3 bytes) to disks measured in GiB (1024^3) remember that capacity numbers given in GiB may appear smaller. For example, 1023 GiB = 1098.4 GB.
Disk throughput is measured in input/output operations per second (IOPS) and MBps where MBps = 10^6 bytes/sec.
Data disks can operate in cached or uncached modes. For cached data disk operation, the host cache mode is set to ReadOnly or ReadWrite. For uncached data disk operation, the host cache mode is set to None.
To learn how to get the best storage performance for your VMs, see Virtual machine and disk performance.
Expected network bandwidth is the maximum aggregated bandwidth allocated per VM type across all NICs, for all destinations. For more information, see Virtual machine network bandwidth.
Upper limits aren't guaranteed. Limits offer guidance for selecting the right VM type for the intended application. Actual network performance will depend on several factors including network congestion, application loads, and network settings. For information on optimizing network throughput, see Optimize network throughput for Azure virtual machines. To achieve the expected network performance on Linux or Windows, you may need to select a specific version or optimize your VM. For more information, see Bandwidth/Throughput testing (NTTTCP).
