UALink – In May 2024 AMD, Broadcom, Cisco, Google, HPE, Intel, Meta, and Microsoft announced the formation of a group that will form a new industry standard, UALink (Ultra Accelerator Link), to create an ecosystem and provide an alternative to NVIDIA’s NVLink.

  • UALink creates an open ecosystem for Scale-up connections of many Al accelerators
  • Effectively communicate between accelerators using an open protocol
  • Easily expand the number of accelerators in a pod
  • Provide the performance needed for compute-intensive workloads now and in the future

A scale-up memory semantic fabric has significant advantages. Scale-out is covered by Ultra Ethernet and the industry is aligned behind the Ultra Ethernet Consortium (UEC) to connect multiple pods with the ability to scale multiple pods.
