Volta is ready, but the fabrication process isn't. The original Volta designed would have needed a 10nm processes, but Nvidia have officially announced releases of Volta cores on 12nm TSMC with mass available Q3 this year for the driver PX units.Driver PX uses a GPU core at about the 160 level, so mid sized Volta chips may not be that far away but a lot will depend exactly what Nvidia wants with Volta for Gaming. Volta has mostly been discussed in terms of HPC, deep learning and autonomous cars. Volta could be quite segregated with a very different gaming chip. Pascal already separated out the GP100 for HPC use. There could be a simpler Volta for gaming built on TSMC 12nm by the end of the year, of a more complex design on 10nm next year.
