AWS unveiled EBS-optimized Amazon EC2 instances—the C8gb, M8gb, and R8gb families—in 48xlarge sizes, as well as metal-48xl sizes for C8gb and R8gb. These instances use AWS Graviton4 processors, delivering approximately 30% better compute performance compared to the preceding Graviton3 generation.
With up to 300 Gbps EBS bandwidth, 1440K IOPS, and 400 Gbps networking bandwidth, these instances provide top-tier block storage and network throughput. Support for Elastic Fabric Adapter enables lower latency and improved cluster performance, targeting workloads demanding high scalability and throughput. Availability was announced for US East (N. Virginia) and US West (Oregon).
