Vultr to deploy AMD Instinct MI355X GPUs in a 20 MW Chennai AI cluster

Cloud infrastructure provider Vultr said it will build a new 20-megawatt AI supercluster in Chennai, India, filled with AMD Instinct MI355X accelerators. Vultr describes it as India's largest AMD Instinct deployment and its second very large AMD AI site after Springfield, Ohio. The cluster is aimed at AI labs, startups, enterprises and research institutions and will run on AMD's ROCm software, while Vultr plans further capacity in 2027 using MI455X GPUs and the Helios rack-scale architecture. The news extends a pattern of cloud operators committing to AMD Instinct hardware, which matters for AMD's data center GPU revenue outlook, though the size and timing of the purchase are not disclosed in the sources reviewed.
