The latest generation compute optimized Amazon EC2 C7g instances are generally available. C7g instances are the first instances powered by the latest AWS Graviton3 processors and deliver up to 25% better performance over Graviton2-based C6g instances for a broad spectrum of applications such as application servers, microservices, batch processing, electronic design automation (EDA), gaming, video encoding, scientific modeling, distributed analytics, high performance computing (HPC), CPU-based machine learning (ML) inference, and ad serving.
AWS Graviton3 processors are the latest generation of custom-designed AWS Graviton processors that enable the best price performance for workloads in Amazon Elastic Compute Cloud (Amazon EC2). They offer up to 2x better floating-point performance, up to 2x faster crypto performance, and up to 3x better ML performance, including support for bfloat16, compared to AWS Graviton2 processors. Graviton3-based C7g instances are the first generally available instances in the cloud to feature the latest DDR5 memory, which provides 50% more memory bandwidth compared to DDR4, to enable high-speed access to data in memory. Graviton3-based instances also use up to 60% less energy for the same performance than comparable EC2 instances, enabling you to reduce your carbon footprint in the cloud. Amazon EC2 C7g instances are built on the AWS Nitro System, a collection of AWS designed hardware and software innovations that enable the delivery of efficient, flexible, and secure cloud services with isolated multi-tenancy, private networking, and fast local storage. They offer up to 30 Gbps enhanced networking bandwidth and up to 20 Gbps of bandwidth to the Amazon Elastic Block Store (Amazon EBS).
Since the preview announcement at re:Invent 2021, hundreds of customers, including Epic Games, Formula 1, NextRoll, Snap, Sprinklr, and Twitter, have tested their workloads on Graviton3-based C7g instances and observed significant performance improvement over Graviton2-based C6g instances. Twitter ran a number of tests representative of their workloads and found that C7g delivered up to 80% better performance than the previous generation C6g. In addition, they reported a reduction in tail latency of as much as 35%. Formula 1 ran their Computational Fluid Dynamics workloads on C7g and found them to deliver 40% better performance than C6g. Honeycomb.io, an early adopter of Graviton, saw a 35% performance improvement and a 30% reduction in latency compared with C6g for their telemetry ingestion workload.
Amazon EC2 instances powered by the AWS Graviton family of processors, including C7g instances, are supported by many popular Linux operating systems, including Amazon Linux 2, Red Hat Enterprise Linux, SUSE, and Ubuntu. The AWS Graviton Ready program provides you with several certified solutions for security, monitoring and management, containers, and CI/CD from third-party vendors that can be used on Graviton-based instances. Many AWS services also support Graviton-based instances, making it quick and easy for you to realize the price performance gains. AWS services that support Graviton-based instances include Amazon Elastic Kubernetes Service (Amazon EKS), Amazon Elastic Container Service (Amazon ECS), AWS Lambda, AWS Fargate, Amazon Aurora, Amazon Relational Database Service (Amazon RDS), Amazon EMR, and Amazon ElastiCache.
The Amazon EC2 C7g instances are now available in the following AWS US Regions: US East (N. Virginia) and US West (Oregon). They are available in 8 sizes, with 1, 2, 4, 8, 16, 32, 48, and 64 vCPUs, and are purchasable On-Demand, as Reserved Instances, as Spot Instances, or as part of Savings Plans. To get started with AWS Graviton3-based Amazon EC2 C7g instances, see the AWS Management Console, AWS Command Line Interface (CLI), and AWS SDKs. You can also get started with Graviton-based instances for no charge with the T4g free trial, which provides up to 750 hours per month with the t4g.small instances through December 31, 2022.
