Context Before
For VR NVL72, the design has turned toward cableless given the higher density and manufacturing complexity of AI server. The cost saved on improving higher manufacturing yields and assembly time reduction more than offsets the higher cost of the upgraded PCB materials. It is critical that all the factors that contribute towards insertion loss in the PCB are mitigated, hence PCB material upgrades are necessary for VR NVL72. We break down the cost by component here ↗.
PCB Materials Upgrade and Area Growth
Evidence
PCB content value in VR NVL72 will grow significantly compared to that of GB200/GB300. The two main drivers of this content growth are significant material upgrades and the notable increase of high-end PCB area and layers. 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.
