Starting today, Amazon Elastic Compute Cloud (Amazon EC2) C9g and C9gd instances, powered by AWS Graviton5 processors, are available in the Asia Pacific (Tokyo) region. AWS Graviton5 processors are the fifth generation of custom-designed CPUs, delivering the best price performance for compute-intensive workloads running on Amazon EC2.

[C9g and C9gd instances](https://aws.amazon.com/ec2/instance-types/c9g/) deliver up to 25% better compute performance compared to AWS Graviton4-based C8g and C8gd instances. They are up to 30% faster for databases, up to 35% faster for web applications, and up to 35% faster for machine learning. These instances are built on the sixth-generation [AWS Nitro System](https://aws.amazon.com/ec2/nitro/) and are the first to feature the [Nitro Isolation Engine](https://aws.amazon.com/blogs/compute/aws-nitro-isolation-engine-formally-verifying-the-hypervisor-in-the-aws-nitro-system/), harnessing formal verification to provide mathematical assurance that customer workloads are isolated from each other and AWS operators, pioneering a new standard for mathematically proven cloud security.

C9g instances are ideal for workloads such as high-performance computing (HPC), batch processing, gaming, video encoding, scientific modeling, distributed analytics, CPU-based machine learning (ML) inference, real time analytics, and ad serving. C9gd instances offer local NVMe-based SSD block-level storage for customers running compute-intensive workloads that also require high-speed, low-latency local storage for scratch space, temporary files, and caches.

C9g and C9gd instances are available for purchase in Asia Pacific (Tokyo) via Savings Plans, On-Demand, Spot instances, Dedicated instances, or Dedicated hosts.
