Amazon EC2 R9g and R9gd instances powered by AWS Graviton5 processors are now generally available

This article announces the general availability of Amazon EC2 R9g and R9gd instances powered by AWS Graviton5 processors, delivering significant performance improvements for memory-intensive workloads.

• Up to 25% higher compute performance per vCPU compared to Graviton4-based R8g instances
• DDR5 8800 MT/s memory (fastest in cloud), 5x larger L3 cache, and up to 2x higher network/EBS bandwidth
• R9gd instances include local NVMe SSD storage for fast, low-latency workloads like databases and caching
• Support for Instance Bandwidth Configuration to optimize EBS and VPC networking allocation by 25%
• Nitro Isolation Engine provides formally verified security isolation between instances
• Available in 11 sizes from medium to metal-48xl across US East, US West, and Europe regions
• No code changes required for migration from R8g; works with EKS, ECS, and standard Kubernetes

R9g and R9gd instances enable better performance and energy efficiency for memory-intensive applications including databases, caching, analytics, and containerized workloads.
