CPU and System Topology
Server Description
An ARM64 compute-optimized instance delivering high-density dedicated cores and top-tier memory bandwidth for parallelized workloads.
Amazon Web Services c8g.12xlarge is a compute-optimized instance powered by 48 dedicated physical cores of the ARM64 AWS Neoverse-V2 processor running at 2.8 GHz. Operating on the Nitro hypervisor, it features 96.0 GB of RAM, providing a 2.0 GB per core ratio, and delivers a baseline network bandwidth of 22 Gbps. The instance lacks local storage and GPU accelerators. Benchmarks highlight top-tier multi-core capabilities, software compilation speeds, and memory bandwidth, alongside average single-core performance. This hardware profile offers high resource density and qualitative cost-efficiency for multi-threaded tasks. It is highly suited for database operations, static web serving, software compilation, and parallelized compute workloads.
