Server Description
An ARM64 compute-optimized instance featuring forty-eight dedicated cores and high-speed seventy-five gigabit network bandwidth for multi-threaded workloads.
Amazon Web Services c6gn.12xlarge is a compute-optimized instance built on the AWS Nitro hypervisor and powered by 48 dedicated ARM64 physical cores via the AWS Graviton Neoverse-N1 processor. Operating at 2.5 GHz, it includes 96.0 GB of memory, resulting in 2.0 GB per core, and lacks local storage or GPU accelerators. The instance features a high baseline network bandwidth of 75 Gbps. Performance benchmarks show strong multi-core capabilities, with a stress-ng multi-core score of 72814.16, though single-core performance remains average to weak. Memory read bandwidth reaches 167.25 GB/sec for large blocks. This hardware profile is suited for network-bound compute workloads, multi-threaded batch processing, and static web serving, offering a cost-efficient alternative to x86 architectures for workloads optimized for ARM64 multi-core scaling.
