Context Before
Source: Nvidia VR NVL72 Component BoM and Power Budget Model ↗
Evidence
With the Strata board bigger than the Bianca board and the extra peripheral boards in the compute tray, we estimate that the area of high end PCB board increases by ~2.3 times from GB300 to VR NVL72
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
SemiAnalysis 估計 high-end PCB board area 從 GB300 到 VR NVL72 約增加 2.3 倍。
