Nvidia's CPO Roadmap - Line hint:
241
Context Before
Nvidia’s approach has been to use copper where they can, and optics where they must. The architecture of NVL1152 in the Feynman generation will follow the same principle. It is clear that the NVL1152 will adopt CPO to connect between racks, but
Evidence
from GPUs to NVLink Switches is currently copper POR.
Context After
Nvidia is unable to achieve another doubling of electrical lane speed from 224Gbit/s bi-di to 448Gbit/s uni-di means bandwidth isn’t that amazing.
② Atomic Claim
目前從 GPU 到 NVLink Switch 的 POR 仍採 copper。
