Amazon EC2 C7g instances

Best price performance for compute-intensive workloads in Amazon EC2

Amazon EC2 C7g instances, powered by the latest generation AWS Graviton3 processors, provide the best price performance 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 AWS Graviton2-based C6g instances. C7g instances are the first in the cloud to feature DDR5 memory, which provides 50% higher memory bandwidth compared to DDR4 memory to enable high-speed access to data in memory.

Best price performance for compute-intensive workloads in Amazon EC2

C7g instances deliver up to 25% better performance over Graviton2-based C6g instances. They are ideal for a large number of compute-intensive applications, such as high performance computing, video encoding, gaming, and CPU-based machine learning inference, that are built on Linux.

Enhanced security and maximized resource efficiency

C7g instances are powered by AWS Graviton3 processors and are built on the AWS Nitro System. AWS Graviton3 processors offer enhanced security to customers with always-on memory encryption, dedicated caches for every vCPU, and support for pointer authentication. The AWS Nitro System is a combination of dedicated hardware and a lightweight hypervisor that delivers isolated multi-tenancy, private networking, and fast local storage. C7g instances also support encrypted Amazon Elastic Block Store (EBS) volumes by default.

Extensive software support

AWS 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 AWS and software partners also support AWS Graviton-based instances. The AWS Graviton Ready program offers certified solutions from partner software vendors that can be used on AWS Graviton-based instances.


Powered by AWS Graviton3 processors

AWS Graviton3 is the latest generation of AWS-designed Arm-based processors that provide the best price performance for workloads in Amazon EC2. AWS 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 AWS Graviton2 processors. Additionally, Graviton3 processors deliver up to 3x better performance compared to Graviton2 processors for ML workloads, including support for bfloat16. 

High performance networking and storage

C7g instances deliver 20% higher enhanced networking bandwidth compared to C6g instances for network intensive applications, such as network appliances and data analytics. These instances support Elastic Fabric Adapter (EFA), a network interface for EC2 instances. You can use it to run applications that require high inter-node communication at scale, such as HPC and video encoding.

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, delivering high performance, high availability, and high security while reducing virtualization overhead.

Customer Testimonials

Epic Games

Founded in 1991, Epic Games is the creator of Fortnite, Unreal, Gears of War, Shadow Complex, and the Infinity Blade series of games. Epic’s Unreal Engine technology brings high-fidelity, interactive experiences to PC, console, mobile, AR, VR, and the web.

“As we look to the future and building increasingly immersive and compelling experiences for players, we are excited to use AWS Graviton3-based EC2 C7g instances. Our testing has shown they are suitable for even the most demanding latency-sensitive workloads while providing significant price performance benefits and expanding what is possible within Fortnite and any Unreal Engine-created experience.” 

Mark Imbriaco, Senior Director of Engineering at Epic Games

Formula 1

Formula 1 (F1) racing began in 1950 and is the world’s most prestigious motor racing competition, as well as the world’s most popular annual sporting series.

“We had already seen that Graviton2-based C6gn instances provided us the best price performance for some of our CFD workloads. We have now found Graviton3 C7g instances to be 40% faster than the Graviton2 C6gn instances for those same simulations. We’re excited that EFA will be standard on this instance type, and given this much-improved price performance, we expect Graviton3-based instances to become the optimal choice to run all of our CFD workloads.”

Pat Symonds, CTO at Formula 1 Management logo develops an observability platform that allows engineering teams to visualize, analyze, and improve cloud application quality and performance.

“We're excited to have tested our high-throughput telemetry ingestion workload against early preview instances of Graviton3 and have seen a +35% performance increase for our workload over Graviton2. We were able to run 30% fewer instances of C7g than C6g serving the same workload, and with 30% reduced latency. Once this instance type reaches production, we believe we'll see over 50% price-performance improvement over Intel instances overall.”

Liz Fong-Jones, Principal Developer Advocate,

Twitter logo

Twitter is what’s happening and what people are talking about right now.

“Twitter is working on a multi-year project to leverage AWS Graviton-based EC2 instances to deliver Twitter timelines. As part of our ongoing effort to drive further efficiencies, we tested the new Graviton3-based C7g instances. Across a number of benchmarks that we've found to be representative of the performance of Twitter workloads, we found Graviton3-based C7g instances deliver 20-80% higher performance vs. Graviton2 based C6g instances, while also reducing tail latencies by as much as 35%. We are excited to utilize Graviton3-based instances in the future to realize significant price performance benefits."
