Context Before
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.
Evidence
The Orchid board is the main contributor to the delta of total high-end PCB area between GB300 and VR NVL72 rack.
Context After
② Atomic Claim
Orchid board 是 GB300 與 VR NVL72 rack 之間 total high-end PCB area 差異的主要貢獻者。
