The [DGX-2][a] introduces NVIDIA’s new NVSwitch, enabling 300 GB/s chip-to-chip communication at 12 times the speed of PCIe.
With NVLink2, it enables sixteen Nvidia V100-SXM3 GPUs in a single system, for a total bandwidth going beyond 14 TB/s.

Featuring pair of Xeon 8168 CPUs, 1.5 TB of memory, and 30 TB of NVMe storage,
we get a system that consumes 10 kW, weighs 163.29 kg, but offers perfomance in excess of 130TF.
