Context Before
We have more detailed power and architecture details in our VR NVL72 Component BoM and Power Budget Model ↗.
Networking: NVLink 6, Rubin Scale Out
Evidence
NVIDIA’s gen-on-gen innovations are evolutionary and not revolutionary. With GPU scale-up and scale-out bandwidth doubling approximately every 18 months, the copper infrastructure in NVIDIA racks are being innovated to accommodate higher bandwidth workloads. Scale-up network infrastructure will eventually involve optics to build larger world sizes, but that is the topic of a separate article.
Context After
The below table shows the evolution of scale-up and scale-out networking speeds. NVLink 6 used in Vera Rubin doubles NVLink bandwidth by implementing bi-directional signaling over the same number of copper cables - effectively delivering 4 Lanes of 200G per NVLink. Much more on this in the following sections.
