Description

The new NVIDIA® DGX-1 is similar to the previous generation offering based Pascal, but is powered by eight Tesla V100s GPUs, linked together via next-gen NVIDIA® NVLink interconnect technology that ups the bandwidth per GPU to 300GB/s. The rest of the system consists of:

  • Dual, 20-core Intel® Xeon® E5-2698 CPUs
  • 512GB of RAM
  • four 1.92TB SSDs in RAID 0
  •  a pair of 10GbE connections

There are a total of 40,960 CUDA cores (5,120 Tensor cores) in the system, with 128GB of total GPU memory, spread across those Tesla V100 processors. All told, the Volta-infused DGX-1 offers up to 960 TFLOPs of FP16 compute performance, versus 170 TFLOPs for the original, with significantly more bandwidth on tap.
