Context Before
Source: Nvidia VR NVL72 BoM and Power Budget Model ↗
Evidence
On a side note, VR NVL72 was initially known as VR NVL144 as Jensen math ↗ from GTC 2025 defined the number of GPU as the number of GPU compute die in system (with 2 compute dies per package and 72 Rubin packages per Oberon rack = 144 compute die). The naming was changed back to VR NVL72 to represent the 72 Rubin GPU packages in the system in late December. This was right before CES 2026 where the naming was officially confirmed as VR NVL72.
