Server Description
A high-bandwidth, 64-core ARM64 compute instance designed for network-intensive workloads, software compilation, and distributed multi-threaded applications.
Amazon Web Services c7gn.16xlarge is a compute-optimized instance powered by a 64-core AWS Graviton3 Neoverse-V1 ARM64 processor running at 2.6 GHz. It features 128.0 GB of memory, providing 2.0 GB per core, and lacks local storage and GPUs. The instance delivers a baseline network bandwidth of 200 Gbps. In benchmark evaluations, the c7gn.16xlarge demonstrates top-tier performance in software compilation and multi-core Geekbench tests, alongside strong memory bandwidth and database operations. However, single-core performance remains average, and small-model LLM text generation is poor. This server offers high resource density and qualitative cost efficiency for multi-threaded, network-heavy workloads. It is best suited for network-intensive applications, software compilation, and distributed databases.
