Built for AI Factories
AMD Instinct™ MI455X
Power your AI workloads with MI455X in Helios™ rack-scale architecture, combining next-generation HBM4, massive memory bandwidth, and ROCm-optimized AMD infrastructure for frontier-scale training and inference.
MI455X on TensorWave
Experience true rack-scale dominance with AMD's groundbreaking Helios architecture. Integrating up to 72 MI400-series GPUs (such as the MI455X) into a single rack, providing over 31 TB of aggregate HBM4 memory and high-bandwidth connectivity through optimized direct liquid cooling, UALink interconnects, and an Ethernet-forward approach. This dense, cohesive design supports large deployments more efficiently than traditional multi-rack setups.
