Radix in silicon chips influences latency

Radix refers to the number of ports a network chip supports. It plays a crucial role in network design by impacting job completion time (JCT) and latency for AI workloads.

A higher radix allows more simultaneous connections and is vital for scalable networking.

Cisco Silicon One features the industry's highest radix with 512 x 100GE Ethernet ports.

In our example, Silicon One's high radix flattens the network, reducing latency from five hops to three. This is crucial in complex networks with many switches, maintaining agility in large-scale, hyper-scale operations.
