AWS extended availability of C8gb instances powered by Graviton4 processors to regions including US East (Ohio), US West (N. California), Europe (multiple locations), and Africa (Cape Town). These instances provide up to 30% better compute performance compared to Graviton3 equivalents and deliver high EBS bandwidth (up to 300 Gbps) and IOPS suitable for performance-intensive workloads like high-performance file systems.
The instances range up to 48xlarge size with substantial memory (384 GiB) and networking bandwidth (up to 400 Gbps), supporting Elastic Fabric Adapter (EFA) networking on large sizes for reduced latency in clustered environments. While AWS cites performance improvements, independent benchmarks can confirm suitability for specific workloads.
