Along with the announcement of the new Tesla A100 based on Ampere, Nvidia also officially announced its new artificial intelligence system DGX A100, based on this graphics and accompanied by two AMD EPYC processors to take advantage not only of the great computing power but also a large number of PC-E 4.0 lines.
Nvidia decided to use not only one but two AMD EPYC 7742 with a total of 128 cores and 256 threads and 256 PCI-E 4.0 lines for expansion. These PCI-E 4.0 lines are used to connect the 8 Tesla A100 cards, and also provide connectivity to the 8-port Infiniband NIC Mellanox ConnectX 200 Gbps, the NVLINK switches, two 1.92TB M.2 SSDs, and four U.2 SSDs for a total of 15TB. Other features include 1 TB of 16-channel RAM and the Ubuntu operating system.
Obviously a system with these features is not economical at all. Nvidia sells the new DGX A100 system for 199,999 USD, and it is already available for pre-order.
