Submission + - News from Nvidia's GTC: updated Tesla/Tegra roadmaps (

gentryx writes: Today Nvidia's founder Jen-Hsun Huang has revealed two new future architectures which are currently being worked on: Volta in the Tesla line and Parker in the Tegra line. Volta will feature 3D chip stacks with through-silicone vias and 1 TB/s of memory bandwidth. Such an off-chip bandwidth would not be possible with the current technology which runs all connections through the rim of the chip. However, these stacks also increase thermal density, which may create other problems. Parker is to use FinFET transistors, which indicates that Nvidia will stick with TSMC as its fabrication partner.

Huang also announced the Nvidia GRID VCA (visual computing appliance), a machine stuffed with 8 dual-chip GPUs, which might be regarded as a GPU mainframe by some, or, since it runs virtual machines, a GPU cloud by marketing.

More details and some key slides are available here.
