AWS Graviton5-powered EC2 R9g and R9gd instances are now generally available

New Graviton5 Instances Launched

Amazon EC2 R9g and R9gd instances, featuring AWS Graviton5 processors, have reached general availability. These memory-optimized instances are designed for workloads requiring high memory capacity and performance.

Performance Improvements

The new R9g instances deliver up to 25% better compute performance compared to the previous Graviton4-based R8g instances. This improvement is attributed to enhancements in the Graviton5 processor architecture, including faster memory and increased cache sizes.

Key Hardware Upgrades

Graviton5 processors incorporate DDR5 8800 MT/s memory, an increase from the 5600 MT/s in Graviton4. They also feature a 5x larger L3 cache for improved data locality and up to 2x higher network and EBS bandwidth for the largest instance sizes, reaching up to 100 Gbps network and 72 Gbps EBS on the 48xlarge instance.

Workload Suitability

R9g instances are optimized for memory-intensive applications such as databases, in-memory caches (Valkey, Redis, MemCached), and real-time big data analytics. R9gd instances further include local NVMe-based SSD block-level storage, catering to workloads that require fast, low-latency local storage, including open-source databases and large caching applications.

Underlying Technology

All R9g and R9gd instances operate on the AWS Nitro System, which offloads virtualization, storage, and networking functions to dedicated hardware. These instances also integrate the Nitro Isolation Engine (NIE), a security enhancement previously introduced with C9g and M9g instances, which enforces isolation between instances.
