Context Before

These power profiles are software managed. Users can also choose whatever max power draw they prefer (as long as it is no more than 2,300W per GPU) and this has been the case for previous GPU generations as well. Several hyperscalers and labs have chosen to run their GPUs at lower power to optimize for performance per Watt as well as taking into account power availability constraints.

Evidence

For the mechanical structure of the Rubin package, upgrades have also been made with the addition of an upgraded heat spreader and a stiffener.

Context After

This compares to Blackwell B200 and B300 packages that only have a heat spreader lid. The heat spreader lid allows more equal distribution of heat exiting the package. It also provides mechanical support for the package to prevent warpage.

② Atomic Claim

Rubin package 的 mechanical structure 也有升級，新增 upgraded heat spreader 與 stiffener。
