Amazon Elastic Compute Cloud (Amazon EC2) C8g instances, powered by the latest-generation AWS Graviton4 processors, provide the best price performance in Amazon EC2 for compute-intensive workloads. Amazon EC2 C8g instances are ideal for compute-intensive workloads, such as high performance computing (HPC), batch processing, gaming, video encoding, scientific modeling, distributed analytics, CPU-based machine learning (ML) inference, and ad serving. C8g instances offer up to 30% better performance and larger instance sizes with up to 3x more vCPUs and memory than the seventh-generation AWS Graviton3-based C7g instances.

Benefits
High performance
C8g instances deliver up to 30% better performance over Graviton3-based C7g instances. These instances include DDR5-5600 memory and are ideal for compute-intensive workloads, such as HPC, batch processing, gaming, video encoding, scientific modeling, distributed analytics, CPU-based ML inference, and ad serving.
Maximized resource efficiency
C8g instances are built on the AWS Nitro System. The AWS Nitro System is a combination of dedicated hardware and a lightweight hypervisor that delivers isolated multitenancy, private networking, and fast local storage.
Extensive software support
AWS Graviton-based instances are supported by most popular Linux operating systems. Many popular applications and services for security, monitoring and management, containers, and continuous integration and delivery (CI/CD) from AWS and software partners also support AWS Graviton-based instances. The AWS Graviton Ready program offers certified solutions from AWS Partner software vendors that you can use on AWS Graviton-based instances.
Features
Powered by AWS Graviton4 processors
AWS Graviton4 is the latest generation of server processors designed by AWS that provide the best performance and energy efficiency for workloads in Amazon EC2. AWS Graviton4 processors deliver up to 30% better compute performance than Graviton3 processors.
Enhanced security
AWS Graviton4 processors offer enhanced security with always-on memory encryption, dedicated caches for every vCPU, and support for pointer authentication. C8g instances also support encrypted Amazon Elastic Block Store (Amazon EBS).
Built on the AWS Nitro System
The AWS Nitro System is a rich collection of building blocks that offloads many of the traditional virtualization functions to dedicated hardware and software. It delivers high performance, high availability, and high security, thus reducing virtualization overhead.
