NVIDIA CEO Jen-Hsun Huang told the conference:
Volta is going to solve one of the biggest challenges facing GPUs today, which is access to memory bandwidth. We never seem to have enough! This is unbelievable stuff.
The speed is made possible by stacking DRAM layers on a single chip and drilling holes through the silicon to connect them. This far ahead, the company has sensibly avoided committing itself to either a price or a more specific release date.
