Server Description
An arm64 compute-optimized server featuring sixty-four dedicated physical cores and high-speed one-hundred gigabit baseline network bandwidth.
Compute OptimizedGeneral Purpose
Amazon Web Services c6gn.16xlarge is an arm64 compute-optimized server instance powered by 64 dedicated physical cores of the AWS Graviton Neoverse-N1 processor running at 2.5 GHz. Operating on the Nitro hypervisor, it features 128.0 GB of RAM, 100 Gbps of baseline network bandwidth, and no local storage or GPU accelerators. Benchmarks show strong multi-core CPU performance, high cached memory bandwidth, and high throughput for Redis SET operations and static web serving. However, single-core performance and single-threaded compression tasks are relatively weak. Qualitatively, the instance offers high physical core density and network capacity for its resource class. It is suited for multi-threaded compute tasks, network-intensive applications, software compilation, and caching workloads.
