The newest generation of Amazon Elastic Compute Cloud EC2 C7gn instances, powered by AWS Graviton processors, are now generally available, according to AWS. For network-intensive workloads, Amazon EC2 C7gn instances with the new 5th generation AWS Nitro Cards offer the highest network bandwidth, the best packet-processing speed, and the best pricing. Compared to equivalent current generation x86-based network optimised instances, C7gn instances offer up to 200 Gbps network bandwidth and up to 3x greater packet-processing speed per vCPU. The AWS Nitro System is the foundation for Amazon EC2 C7gn instances.
The Nitro System is a group of AWS-designed technological advancements in hardware and software that enables the delivery of effective and adaptable cloud services with improved security, isolated multi-tenancy, private networking, and quick local storage. Utilise the improved networking capabilities to grow throughput and performance while reducing operating costs for applications that are network-intensive. Network virtual appliances, data analysis, and CPU-based artificial intelligence and machine learning (AI/ML) inference are a few workload examples.
C7gn instances come in 8 distinct instance sizes for greater scalability. These instances provide Amazon Elastic Block Store (EBS) with up to 40 Gbps of bandwidth. For applications deployed on densely connected clusters, C7gn instances offer Elastic Fabric Adapter (EFA) networking on the 16xlarge scale, resulting in decreased latency and increased cluster performance.

Enhanced security and maximized resource efficiency
The AWS Nitro System serves as the foundation for C7g and EC2 C7gn instances. The AWS Nitro System offers fast local storage, private networking, and isolated multi-tenancy with a lightweight hypervisor and specialized hardware. With pointer authentication capability, separate caches for each vCPU, and always-on memory encryption, the AWS Graviton3 and AWS Graviton3E processors provide increased security. Additionally, by default, these instances support encrypted Amazon Elastic Block Store (EBS) volumes.
Extensive software support
Numerous Linux operating systems, such as Amazon Linux 2, Red Hat Enterprise Linux, SUSE, and Ubuntu, support instances hosted on AWS Graviton. AWS Graviton-based instances are also supported by a number of well-known security, monitoring, and management, container, and continuous integration and delivery (CI/CD) apps and services from AWS and software partners. Certified software solutions from partner vendors are available for use on AWS Graviton-based instances through the AWS Graviton Ready program.
Amazon EC2 C7gn Features
Powered by AWS Graviton3 processors
AWS Graviton3, the latest Arm-based processor from AWS, provides high performance at a low cost for Amazon EC2 applications. AWS Graviton3 processors have 25% faster computation, 2x faster floating-point, and 2x faster cryptographic workload performance than AWS Graviton2. Graviton3 processors surpass Graviton2 processors in machine learning by three times using bfloat16. C7gn instances use AWS Graviton3E processors, which perform vector-instructions 35% better than Graviton3. HPC applications benefit from increased performance as a result of this enhancement.
High-performance interfaces
Compared to C6g and C6gn instances, C7g and C7gn instances offer 50% more bandwidth With their cutting-edge DDR5 memory. Local instance storage (C7gd) is another option for C7g instances. For network-intensive applications like data analytics and network appliances, C7gn instances offer twice as much increased networking bandwidth as C6gn instances. The Elastic Fabric Adapter (EFA) is supported in the 16xlarge and bare-metal sizes for instances C7g, C7gd, and C7gn.
