AMD Helios rack-scale platform
AMD's open rack-scale design combining 72 Instinct MI455X GPUs, networking and management, built on the Open Rack Wide standard.
- Type
- Technology
- Where it sits
- A second rack-scale route for AI capacity, using open scale-up and scale-out networking rather than a proprietary fabric.
- Constraint
- Partner systems depend on AMD delivering the MI455X and new CPUs; one trade-press report on HPE's Helios offer said availability was pending that delivery.
What we checked
- AMD's August 2026 blog describes 72 MI455X GPUs per rack with 31 TB of HBM4 memory, with scale-up using UALink over Ethernet and scale-out using Ultra Ethernet-based networking. (source)
- It is reported that HPE will offer a Helios rack with a Juniper scale-up switch built on Broadcom Tomahawk 6 silicon. (source)
