Context Before
Source: Nvidia VR NVL72 Component BoM and Power Budget Model ↗
Evidence
In Grace Blackwell, the only boards with high end material are the Bianca board with M7 grade CCL and the NVSwtich board with M8 grade CCL, leaving front half of the compute tray uncovered by high end PCB board
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 Grace Blackwell 中，使用 high-end material 的 board 僅有採 M7 grade CCL 的 Bianca board，以及採 M8 grade CCL 的 NVSwtich board，因此 compute tray 前半部沒有 high-end PCB board。
