Amazon expanded availability of EC2 C8gn instances, built on AWS's latest Graviton4 processors, to Europe (Milan) and Asia Pacific (Hong Kong). These instances deliver up to 30% better compute performance versus the previous Graviton3-based C7gn instances. Featuring 6th generation AWS Nitro Cards, they support up to 600 Gbps network bandwidth—the highest among EC2 network-optimized instances.
Additionally, C8gn supports large instance sizes up to 48xlarge with 384 GiB memory and 120 Gbps EBS bandwidth. Selected sizes enable Elastic Fabric Adapter (EFA) networking for low-latency, high-performance tightly coupled clusters. The instances cater to network-intensive workloads like virtual appliances, data analytics, and AI/ML inference.
