Amazon EC2 C7g Instances

A price performance choice for compute-intensive workloads in Amazon EC2

Overview

Amazon Elastic Compute Cloud (Amazon EC2) C7g instances, powered by the latest generation Amazon Graviton3 processors, provide the a price performance choice in Amazon EC2 for compute-intensive workloads. C7g instances are ideal for high performance computing (HPC), batch processing, electronic design automation (EDA), gaming, video encoding, scientific modeling, distributed analytics, CPU-based machine learning (ML) inference, and ad serving. They offer up to 25% better performance over the sixth-generation Amazon Graviton2-based C6g instances. C7g instances are the first in the cloud to feature Double Data Rate 5 (DDR5) memory, which provides 50% higher memory bandwidth compared to DDR4 memory to enable high-speed access to data in memory.

Benefits

C7g instances deliver up to 25% better performance over Graviton2-based C6g instances . It is ideal for a large number of compute-intensive applications, such as HPC, video encoding, gaming, and CPU-based ML inference, that are built on Linux.
C7g is built on the Amazon Nitro System. Amazon Nitro System is a combination of dedicated hardware and a lightweight hypervisor that delivers isolated multi-tenancy, private networking, and fast local storage. Amazon Graviton3 offer enhanced security with always-on memory encryption, dedicated caches for every vCPU, and support for pointer authentication. These instances also support encrypted Amazon Elastic Block Store (EBS) volumes by default.
Amazon Graviton-based instances are supported by many Linux operating systems, including Amazon Linux 2, Red Hat Enterprise Linux, SUSE, and Ubuntu. Many popular applications and services for security, monitoring and management, containers, and continuous integration and delivery (CI/CD) from Amazon Web Services and software partners also support Amazon Graviton-based instances. The Amazon Graviton Ready program offers certified solutions from partner software vendors that can be used on Amazon Graviton-based instances.

Features

Amazon Graviton3 is the latest generation of Amazon-designed Arm-based processors that provide a price performance choice for workloads in Amazon EC2. Amazon Graviton3 processors deliver up to 25% better compute performance, up to 2x higher floating-point performance, and up to 2x faster cryptographic workload performance compared to Amazon Graviton2 processors. Additionally, Graviton3 processors deliver up to 3x better performance compared to Graviton2 processors for ML workloads, including support for bfloat16. This improvement provides higher performance benefits for HPC applications.
C7g instances use leading edge DDR5 memory to provide 50% higher bandwidth compared to C6g instances. C7g instances have support for Elastic Fabric Adapter (EFA) in the 16xlarge and bare-metal sizes.
The Amazon 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, reducing virtualization overhead.
