AMD launches Helios racks with MI455X; Anthropic to deploy up to 2 GW, OpenAI online Q4
At Advancing AI 2026 (2026-07-23) AMD launched Helios rack-scale systems (72 Instinct MI455X GPUs + 18 EPYC 'Venice' CPUs) into production, claiming up to 30% more tokens per dollar than the leading competitor; Anthropic announced plans for up to 2 GW of MI455X/Helios, and OpenAI expects its first Helios capacity online in Q4 2026 under its 6 GW AMD deal.
Key facts
- Helios: 72 MI455X GPUs + 18 6th-gen EPYC 'Venice' CPUs per rack
- MI455X claimed 34x token throughput vs MI355X; Helios 'up to 30% more tokens per dollar' than leading competitor (AMD claims)
- Anthropic: up to 2 GW of MI455X in Helios
- OpenAI: Helios online from Q4 2026; part of 6 GW multi-generation deal starting with 1 GW of MI450-class in H2 2026
- Customers also include Meta, Microsoft, Oracle, HUMAIN; roadmap MI500 (2027), MI600 (2028)
What happened
AMD's first rack-scale system answers Nvidia's NVL72 and comes with gigawatt-scale commitments from two of the top three frontier labs.
Why it matters
A credible second source of frontier training/inference compute weakens Nvidia's pricing power and diversifies lab supply chains.
