New Amazon EC2 C7gn Instances: Graviton3E Processors and Up To 200 Gbps Network Bandwidth

The C7gn instances that we previewed last year are now available and you can start using them today. The instances are designed for your most demanding network-intensive workloads (firewalls, virtual routers, load balancers, and so forth), data analytics, and tightly-coupled cluster computing jobs. They are powered by AWS Graviton3E processors and support up to 200 Gbps of network bandwidth.

Here are the specs:

Instance Name	vCPUs	Memory	Network Bandwidth	EBS Bandwidth
c7gn.medium	1	2 GiB	up to 25 Gbps	up to 10 Gbps
c7gn.large	2	4 GiB	up to 30 Gbps	up to 10 Gbps
c7gn.xlarge	4	8 GiB	up to 40 Gbps	up to 10 Gbps
c7gn.2xlarge	8	16 GiB	up to 50 Gbps	up to 10 Gbps
c7gn.4xlarge	16	32 GiB	50 Gbps	up to 10 Gbps
c7gn.8xlarge	32	64 GiB	100 Gbps	up to 20 Gbps
c7gn.12xlarge	48	96 GiB	150 Gbps	up to 30 Gbps
c7gn.16xlarge	64	128 GiB	200 Gbps	up to 40 Gbps

The increased network bandwidth is made possible by the new 5th generation AWS Nitro Card. As another benefit, these instances deliver the lowest Elastic Fabric Adapter (EFA) latency of any current EC2 instance.

Here’s a quick infographic that shows you how the C7gn instances and the Graviton3E processors compare to previous instances and processors:

As you can see, the Graviton3E processors deliver substantially higher memory bandwidth and compute performance than the Graviton2 processors, along with higher vector instruction performance than the Graviton3 processors.

C7gn instances are available in the US East (Ohio, N. Virginia), US West (Oregon), and Europe (Ireland) AWS Regions in On-Demand, Reserved Instance, Spot, and Savings Plan form. Dedicated Instances and Dedicated Hosts are also available.
