TLDR

AMD's Helios rack-scale system links 72 Instinct MI455X accelerators into one compute domain. The company lists more than 18,000 CDNA 5 GPU compute units, 4,600 Zen 6 CPU cores and 31TB of HBM4 memory in a single rack. Each MI455X provides 432GB of HBM4 and up to 23.3TB/s of memory bandwidth, while an all-to-all UALoE fabric connects the GPUs in one hop. These are AMD's architecture specifications and positioning, not independent performance results.
