Context Before

Several upgrades are also made on the cold plate for VR NVL72.

Evidence

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.

Context After

The cold plate of the Rubin GPU is upgraded to a “micro-channel cold plate” (MCCP). Essentially, the pitch between the channels in the cold plate is reduced to 100 micron from 150 micron.

② Atomic Claim

每個 Strata module 的 cold plate 都是一體式 module，覆蓋整張 Strata board，包括 2 顆 Rubin GPUs、1 顆 Vera CPU、SOCAMM modules 與各種 VRM components。
