Context Before

The NVLink-C2C chiplet houses the SerDes for the Vera CPU connection, doubled in bandwidth to 1.8TB/s, while

Evidence

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.

Context After

Transistor count has climbed 60% to 336 billion.

② Atomic Claim

較大的 NVLink 6 chiplet 位於晶片另一端，配置 36 條 custom 400G SerDes links，使連到全部 72 顆 Rubin GPU 的 NVLink bandwidth 提升至 2 倍。
