AMD Instinct MI455X Helios 72-GPU Rack (Supermicro)
AMD Instinct MI455X Helios rack — Supermicro’s rack-scale platform with 72 GPUs, 18 AMD EPYC processors and up to 31 TB HBM4, offered for pre-order allocation.
Supermicro AMD Helios Platform is a double-wide OCP Open Rack Wide system built around 72 AMD Instinct MI455X accelerators and 18 sixth-generation AMD EPYC processors. The liquid-cooled Helios architecture uses UALink over Ethernet (UALoE) for scale-up connectivity and AMD Pensando Vulcano networking for scale-out. Supermicro’s public datasheet names the platform without an orderable system part number. This pre-order listing is an allocation inquiry for a complete rack; cooling infrastructure, power and network configuration are scoped with the deployment. Configuration and availability confirmed at quote.
