With speculation about whether AMD will look to utilize PCIe 4.0 in upcoming products looks to be all settled as AMD’s vice president of data center design engineering, Raghu Nambiar confirmed that AMD intends to be an early adopter of PCIe 4.0.
Nambiar said during the recent Broadcom sampling of a new 200G Ethernet controller with 50G PAM-4.
“AMD intends to be an early adopter of PCIe 4.0 to meet the ever-increasing need for efficient, high-performance computing resources,” said Raghu Nambiar, vice president of datacenter design engineering at AMD.
“Broadcom is a valuable contributor to the technology ecosystem and AMD looks forward to the support for our CPU and GPU processor architectures from the Thor PCIe 4.0 product.”
AMD is set to release their first 7nm GPU, Vega 20 targeted for enterprise and aims to release before the end of the year. Will include xGMI technology, essentially an NVLink competitor allowing high-speed GPU-to-GPU interconnect built on AMD’s Infinity Fabric ignoring the limitations of PCIe bandwidth restrictions.
However AMD does not plan to introduce such technologies to the consumer for the time being but going off from this it only makes sense to adopt PCIe 4.0 for the next generation of Zen 2 CPU’s with a heavy focus on EPYC Rome and next generation Navi GPUs.
