Context Before
Source: Nvidia VR NVL72 Component BoM and Power Budget Model ↗
Evidence
For VR NVL72, the Orchid board and the midplane board increases the high end PCB board area in the compute tray covering the front half of the chassis
Context After
Our VR NVL72 Component BoM and Power Budget Model ↗ has provides the $ content breakdown of high end CCL and PCB content for VR NVL72 vs GB200/GB300.
Compute Tray: Thermal
② Atomic Claim
在 VR NVL72 中，Orchid board 與 midplane board 覆蓋 chassis 前半部，使 compute tray 內 high-end PCB board area 增加。
