Oracle Announces Largest AI Supercomputer in the Cloud: Oracle Cloud Infrastructure (OCI) Zettascale10

Strategic Insights

— 1 min read

Oracle has announced Oracle Cloud Infrastructure (OCI) Zettascale10, the largest AI supercomputer in the cloud, with the ability to deliver up to 16 zettaFLOPS of peak performance. This massive computing power is achieved through the connection of hundreds of thousands of NVIDIA GPUs across multiple data centers, forming multi-gigawatt clusters. The new infrastructure is designed to support large-scale AI workloads and has been deployed in collaboration with OpenAI at the Stargate site in Abilene, Texas.

Key Takeaways:

  • Oracle Cloud Infrastructure (OCI) Zettascale10 is the largest AI supercomputer in the cloud, capable of delivering up to 16 zettaFLOPS of peak performance.
  • The supercomputer is built by connecting hundreds of thousands of NVIDIA GPUs across multiple data centers, forming multi-gigawatt clusters.
  • OCI Zettascale10 is powered by Oracle Acceleron RoCE networking architecture, which provides breakthrough scale, extremely low GPU-GPU latency, industry-leading price-performance, and improved cluster utilization.
  • The new infrastructure has been deployed in collaboration with OpenAI at the Stargate site in Abilene, Texas, and will support large-scale AI workloads.
  • OCI Zettascale10 is a powerful evolution of the first Zettascale cloud computing cluster, which was introduced in September 2024.
  • The supercomputer is designed to provide customers with the ability to build, train, and deploy their largest AI models into production using less power per unit of performance and achieving high reliability.
  • Customers will have the freedom to operate across Oracle's distributed cloud with strong data and AI sovereignty controls.

Statistics:

  • Peak performance: up to 16 zettaFLOPS
  • Number of NVIDIA GPUs: hundreds of thousands across multiple data centers
  • Multi-gigawatt clusters: powered by Oracle Acceleron RoCE networking architecture
  • Initial deployments: up to 800,000 NVIDIA GPUs
  • Power efficiency: less power per unit of performance
  • Cluster utilization: improved cluster utilization and strong cost efficiency
