Context Before
Several upgrades are also made on the cold plate for VR NVL72. For each Strata module, the cold plate will be provided as a single module covering the entire Strata board including two Rubin GPUs, one Vera CPU, SOCAMM modules, and the various VRM components. The cold plate of the Rubin GPU is upgraded to a “micro-channel cold plate” (MCCP).
Evidence
Essentially, the pitch between the channels in the cold plate is reduced to 100 micron from 150 micron.
Context After
This increases the surface area and increases the thermal dissipation capacity of the cold plate. Also, there will be a layer of gold plated on the surface contacting the Rubin GPU. The reason for this is to prevent corrosion of the copper from the liquid metal Indium TIM2.
