Nvidia details its itty bitty GB10 superchip for local AI development

Hot Chips Back in 2023, Nvidia's superchip architecture introduced a new programming model for accelerated workloads by coupling the CPU to the GPU via a high-speed NVLink fabric that makes PCIe feel positively glacial.

The only problem? Outside of the datacenter or cloud, there weren't a lot of ways for developers to take advantage of it.

Nvidia's Project Digits — since rebranded as DGX Spark — aims to change that by bringing a miniaturized version of Nvidia's superchip architecture called the GB10 to the masses — or at least to devs with north of $2,999 burning a hole in their pockets.

At Hot Chips this week, GB10 lead architect Andi Skende offered a closer look at its architecture.

Fabbed on TSMC's 3nm manufacturing tech, the GB10 is composed of two distinct compute dies: a CPU tile designed by MediaTek, and a GPU tile designed by Nvidia. These ...
