The new Graviton4-based Amazon EC2 instances—C8g for compute-intensive, M8g for general purpose, and R8g for memory-heavy workloads—were introduced in the AWS Secret East region. These instances deliver up to 30% better performance than Graviton3-based counterparts, featuring up to triple the vCPUs and memory for larger instance sizes.
Built on the Amazon Nitro System, these instances optimize CPU virtualization and I/O operations, enhancing security and performance. AWS highlights up to 40% faster processing in databases and significant speedups for web and Java applications, supporting various use cases including HPC, batch processing, gaming, scientific modeling, and ML inference. This expands AWS's energy-efficient, ARM-based server options in specialized regions.
