Server Description
A dedicated 32-core ARM64 compute-optimized instance delivering 100 Gbps network bandwidth and top-tier memory throughput for demanding workloads.
Amazon Web Services c8gn.8xlarge is an ARM64 compute-optimized server powered by a 32-core AWS Graviton Neoverse-V2 processor running at 2.8 GHz. Operating on the Nitro hypervisor, it features 32 dedicated physical cores, 64.0 GB of system memory, and a baseline network bandwidth of 100 Gbps, with no local storage or GPU hardware. Benchmark results highlight top-tier memory bandwidth and database operations, alongside strong multi-core performance in Geekbench and software compilation. However, large-model LLM inference presents a performance tradeoff, scoring in the bottom 25% for 70B model prompt processing. This instance provides qualitative cost efficiency for high-throughput, network-bound, and compute-intensive workloads. It is highly suited for database operations, static web serving, software compilation, and multi-threaded decompression tasks.
