Rubin Oberon Rack: NVL72 not NVL144 nor NVL36 - Line hint:
125
Context Before
The key difference between the Blackwell and Rubin Oberon architecture is the number of SKUs offered to customers. As Blackwell Oberon was the first ever mass deployment of a rack scale solution with rack power density over 100KW for the GB200 NVL72 SKU, many datacenters did not have the infrastructure ready to support 100kw+ per rack.
Evidence
Nvidia offered two SKUs of Blackwell Oberon: GB200 NVL72 and GB200 NVL36x2.
Context After
The latter being a lower density SKU offered for customers who did not have the infra ready to handle the thermals of a single high density rack.
② Atomic Claim
Nvidia 為 Blackwell Oberon 提供兩種 SKUs：GB200 NVL72 與 GB200 NVL36x2。
