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

Voiced by Polly

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.
