Server Description
A dedicated 48-core ARM64 compute instance delivering strong multi-threaded performance and balanced memory bandwidth for parallelized workloads.
Amazon Web Services c6g.12xlarge is an ARM64 compute-optimized instance featuring 48 dedicated physical cores on AWS Graviton processors running at 2.5 GHz. Built on the Nitro hypervisor, it provides 96.0 GB of memory (2.0 GB per core) and a 20 Gbps baseline network bandwidth, with no local storage or GPU accelerators. Performance benchmarks indicate strong multi-core CPU capabilities, scoring in the top 25% on stress-ng multi-core tests, though single-core performance and single-threaded tasks like gzip compression fall into the bottom 25%. The instance offers a cost-efficient profile for parallelized workloads due to its dedicated physical core density. It is optimized for multi-threaded applications, software compilation, static web serving, and database operations.
