InfiniBand

As AI and High-Performance Computing (HPC) workloads push the boundaries of networking, the demand for ultra-low latency and high bandwidth is more critical than ever. Traditionally, InfiniBand has led the charge in delivering the performance AI workloads need, but Ethernet has been advancing rapidly, thanks to developments led by the Ultra Ethernet Consortium (UEC). With its upcoming 1.0 specification, UEC aims to redefine what Ethernet can achieve at speeds of 400G and 800G, giving InfiniBand significant competition.

In the rapidly evolving fields of high-performance computing (HPC) and artificial intelligence (AI), choosing the right interconnect for your compute nodes is critical. The two most prominent technologies—InfiniBand and Ethernet—have distinct strengths and are increasingly important for meeting the ultra-low-latency, high-throughput demands of modern computing.
