The newly available metal-24xl and metal-48xl instance sizes for M8gn and M8gb families feature AWS Graviton4 processors offering up to 30% better compute performance over Graviton3. M8gn targets network-heavy workloads with up to 600 Gbps network bandwidth, while M8gb is optimized for block storage throughput with up to 300 Gbps EBS bandwidth.
These instances support up to 768 GiB memory and Elastic Fabric Adapter (EFA) networking on larger sizes, enabling high-performance file systems, caching, real-time analytics, and 5G user plane functions. General availability began February 25, 2026, in the AWS US East (N. Virginia) region, facilitating demanding compute and network-intensive applications.
