NVIDIA DGX-2 is a server rack with 16 Volta GPUs and Dual Xeon Platinums for $399,000. It packs a total of 81,920 CUDA Cores with 512 GB HBM2 memory and a 14.4 TB/s aggregate bandwidth and 300 GB/s GPU to GPU. The total power consumption of the rack is 10,000 watts and weighs 350 pounds.

Alexnet five years ago took six days to train with 2 GTX 580s. That can now be done in 18 minutes on DGX-2.

DGX-2 provides 10X the processing power of DGX-1 of six months ago, unveiled in September 2017.

It's $399K for the world's most powerful computer. This replaces $3M of 300 dual-CPU servers consuming 180 kilowatts. This is 1/8th the cost, 1/60th of the space, 18th the power.
