# AMD Launches Helios AI Rack System in a Direct Challenge to Nvidia

**AMD unveiled its Helios rack-scale AI system, built from 72 Instinct MI455X GPUs and 18 EPYC CPUs, aimed squarely at Nvidia's data-center lead.**

## What AMD announced

At its sold-out Advancing AI conference in San Francisco, AMD unveiled Helios, described by [TechCrunch](https://techcrunch.com/2026/07/23/amd-takes-on-nvidia-with-its-helios-ai-rack-scale-system) as AMD's first true rack-scale AI system and a direct challenge to Nvidia's hold on data-center AI hardware. AMD Chair and CEO Dr. Lisa Su called Helios the industry's highest-performance AI rack, and the company said it is now in production and will be deployed by leading AI companies at gigawatt scale.

## Inside a Helios rack

According to AMD's own announcement, each Helios rackscale system combines 72 high-performance AMD Instinct MI455X GPUs with 18 sixth-generation AMD EPYC CPUs, tied together with AMD's Pensando networking and run by AMD's ROCm software. AMD also introduced a separate data-center CPU, the Venice-X, which the company expects to launch in 2027.

## AMD's performance claim against Nvidia

AMD says Helios delivers up to 30% more inference tokens per dollar than what it calls the leading competitive solution, though AMD has not named that comparison configuration in detail, so the figure should be read as AMD's own claim rather than an independently verified benchmark. Nvidia has dominated rack-scale AI systems with its Vera Rubin and Grace Blackwell platforms, and AMD is positioning Helios as its answer to that lead.

## How the specs compare, per The Register

[The Register](https://www.theregister.com/systems/2026/07/23/amd-attacks-the-rack-with-helios-systems-that-rival-nvidias/5277246) reported that, spec for spec, Helios looks bigger and faster than Nvidia's Vera Rubin by nearly every metric on paper. The outlet said Helios has roughly 50% more HBM4 memory and scale-out bandwidth than Vera Rubin, along with 15% to 25% higher performance for AI training workloads. The Register also reported that Vera Rubin's compression technology could give it about a 25% edge over Helios on certain low-precision inference work, while Helios offers roughly 15% higher peak performance on those same calculations. These are third-party comparisons rather than figures either chipmaker has independently certified.

## Who is already on board

AMD said Helios already has a growing list of customers with plans to deploy the system, including OpenAI, Meta, Oracle, Anthropic, and Microsoft. Microsoft said it will expand its Azure infrastructure with Helios, and Anthropic separately announced a strategic partnership with AMD to deploy up to 2 gigawatts of GPUs through the new rack system.
