feature

AWS has announced the general availability of Amazon EC2 R9g and R9gd memory-optimized instances, featuring the new AWS Graviton5 processors. These instances deliver up to 25% better compute performance than Graviton4, with faster DDR5 memory, larger L3 cache, and increased network/EBS bandwidth. Designed for memory-intensive workloads like databases, in-memory caches, and real-time analytics, R9g instances are also AWS's most energy-efficient to date. R9gd variants include fast local NVMe SSD storage, and both types incorporate the Nitro Isolation Engine for enhanced security.

  • Enhanced Isolation with Nitro Isolation Engine (NIE)

    The new instances feature the Nitro Isolation Engine (NIE), an enhancement to the Nitro System that enforces isolation of instances and leverages formal verification. NIE ensures isolation between virtual machines, mediating access to memory, CPU state, and I/O devices through a minimal API set, establishing a mathematically proven standard for cloud security.

  • New EC2 R9g and R9gd Instances with Graviton5 Processors Generally Available

    AWS has launched Amazon EC2 R9g and R9gd memory-optimized instances, now generally available and powered by the new AWS Graviton5 processors. R9g instances offer up to 25% better compute performance compared to Graviton4-based R8g instances, making them suitable for databases, in-memory caches, and big data analytics. The R9gd variants further include local NVMe-based SSD block-level storage for workloads requiring fast, low-latency scratch space.

  • Graviton5 Processor Delivers Enhanced Performance and Efficiency

    Graviton5 processors provide significant hardware improvements, including DDR5 8800 MT/s memory, a 5x larger L3 cache, and up to 2x higher network and EBS bandwidth for larger instance sizes. These processors are designed for energy efficiency, offering better performance per vCPU while consuming less power. Workloads running on R8g instances can migrate to R9g for improved performance without code changes.

  • Instance Bandwidth Configuration and Nitro System Integration

    R9g and R9gd instances support Instance Bandwidth Configuration (IBC), allowing users to adjust bandwidth allocation between Amazon EBS and VPC networking. All instances run on the AWS Nitro System, offloading virtualization, storage, and networking to dedicated hardware for near-bare-metal performance and strong security isolation.

Notes (2) ›
  • Broad Workload Support and Migration Guidance

    R9g and R9gd instances are ideal for memory-intensive Linux-based workloads, containerized and micro-service applications, and support popular programming languages. Migration from R8g typically requires no code changes, and multi-arch container images for Arm64 run without modification. AWS provides resources like the Graviton Getting Started Guide and Graviton Savings Dashboard to assist users.

  • Regional Availability and Flexible Purchase Options

    Amazon EC2 R9g and R9gd instances are available in US East (N. Virginia, Ohio), US West (Oregon), and Europe (Frankfurt) Regions. They can be purchased via Savings Plans, On-Demand, Spot Instances, Dedicated Instances, or Dedicated Hosts, with detailed pricing available on the Amazon EC2 pricing page.
