VR2R-0080

① SA Source

Context Before

The NVLink-C2C chiplet houses the SerDes for the Vera CPU connection, doubled in bandwidth to 1.8TB/s, while the larger NVLink 6 chiplet on the other end of the chip features 36 custom ‘400G’ SerDes links for 2x NVLink bandwidth to all 72 Rubin GPUs.

Evidence

Transistor count has climbed 60% to 336 billion.

Context After

A notable omission from Rubin is the mention of Sparse FLOPs. In previous generations, 2:4 structured sparsity was used to double marketing FLOPs numbers. However, adoption was minimal especially at low precisions due to accuracy losses from the rigid sparsity structure forcing half of the values to be zero. Programmers basically ignored structured sparsity as it was not useful, which caused hardware designs to change as well.
