Q:

What is the difference between HDR and NDR InfiniBand cables?

by 5***m on 2025-07-10 09:00:27

A:

HDR (High Data Rate) supports up to 200Gb/s per port, while NDR (Next Data Rate) can handle 400Gb/s. Both are used for high-performance computing, but NDR is designed for newer-generation systems requiring ultra-high bandwidth.
