Amazon primed to fuse Nvidia's NVLink into 4th-gen Trainium accelerators

Re:Invent Amazon says that its next generation of homegrown silicon will deliver 6x higher performance thanks to a little help from its buddy Nvidia.

At its Re:Invent convention in Las Vegas on Tuesday, Amazon Web Services (AWS) teased its Trainium4 accelerators, which will be among the first to embrace Nvidia's NVLink Fusion interconnect tech for chip-to-chip communications.

NVLink is a high-speed interconnect that allows multiple GPUs spanning multiple systems to pool resources and behave like a single accelerator. Previously, this technology has been limited to Nvidia CPUs and GPUs, but back in May, the AI infrastructure giant announced it was opening the tech to others with the introduction of NVLink Fusion at Computex.

Amazon claims that the technology will allow its Trainium4 accelerators, Graviton CPUs, and EFA networking tech to communicate seamlessly across Nvidia's MGX racks.

In its current form, Nvidia's fifth-gen NVLink fabrics support ...
