At this year's GPU Technology Conference, Huang again unveiled the latest Nvidia GPU architecture, Volta, during today's keynote. And once again, the first product will be the Tesla V100 accelerator for datacenter use. The V100 comes in two flavors. One is a mezzanine card (shown above) designed for interconnection to a server (and other V100s) via Nvidia's proprietary NVLink. The other is a double wide PCIE card.
Since Nvidia has followed the pattern of last year so closely, I have to believe that consumer graphics cards based on Volta are not far in the future. Nvidia expects to start shipping V100s in Q3, behind last year's time phasing for the P100, which was already shipping in small volumes in April. Probably, that means that consumer Volta cards will arrive in late in Q3 or early Q4.
