Comment 0What is the difference between HDR and NDR InfiniBand cables?
by x***m on 2025-07-10 09:34:26
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.
