The NVIDIA A100 Tensor Core GPUs in the DGX Station A100 comes packed with 80 GB of HBM2e memory which is twice the memory size of the original A100. This means that the DGX Station has a total of 320 GB of total available capacity while fully supporting MIG (Multi-Instance GPU protocol) and 3rd Gen NVLink support, offering 200 GB/s of bidirectional bandwidth between any GPU pair & 3 times faster interconnect speeds than PCIe Gen 4. The rest of the specs for the A100 Tensor Core GPUs remain the same.

The system itself houses an AMD EPYC Rome 64 Core CPU with full PCIe Gen 4 support, up to 512 GB of dedicated system memory, 1.92 TB NVME M.2 SSD storage for OS, and up to 7.68 TB NVME U.2 SSD storage for data cache. For connectivity, the system carries 2x 10 GbE LAN controllers, a single 1 GbE LAN port for remote management. Display output is provided through a discrete DGX Display Adapter card which offers 4 DisplayPort outputs with up to 4K resolution support. The AIC features its own active cooling solution.

Talking about the cooling solution, the DGX Station A100 houses the A100 GPUs on the rear side of the chassis. All four GPUs and the CPU are supplemented by a refrigerant cooling system which is whisper quiet and also maintenance free. The compressor for the cooler is located within the DGX chassis.

NVIDIA DGX Station A100 System Performance

As for performance, the DGX Station A100 delivers 2.5 Petaflops of AI training power & 5 PetaOPS of INT8 inferencing horsepower. The DGX Station A100 is also the only workstation of its kind to support the MIG (Multi-Instance GPU) protocol, allowing users to slice up individual GPUs, allowing for simultaneous workloads to be executed faster and more efficiently.

Over the original DGX Station, the new version offers a 3.17x increase in Training performance, 4.35x increase in Inference performance, and 1.85x increase in HPC oriented workloads. NVIDIA has also updated its DGX A100 system to feature 80 GB A100 Tensor Core GPUs too. Those allow NVIDIA to gain 3 times faster training performance over the standard 320 GB DGX A100 system, 25% faster inference performance, and two times faster data analytics performance.

NVIDIA DGX Station A100 System Availability

NVIDIA has announced that the DGX Station A100 and NVIDIA DGX A100 640 GB systems will be available this quarter through NVIDIA's partner network resellers worldwide. The company will also be offering an upgrade option for DGX A100 320 GB system owners to upgrade to the 640 GB DGX variant featuring eight 80 GB A100 Tensor Core GPUs.
