• Source: 開啟完整 SA 文章
• Section: Rubin Oberon Rack: NVL72 not NVL144 nor NVL36
• Line hint: 133

Context Before

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).

Evidence

The naming was changed back to VR NVL72 to represent the 72 Rubin GPU packages in the system in late December.

Context After

This was right before CES 2026 where the naming was officially confirmed as VR NVL72.

② Atomic Claim

到 12 月下旬，命名改回 VR NVL72，以代表 system 內的 72 個 Rubin GPU packages。
