Server Description
An x86_64 compute-optimized instance featuring high-speed networking and dedicated Intel Xeon processors for network-bound and distributed workloads.
Amazon Web Services c5n.9xlarge is an x86_64 compute-optimized instance running on the Nitro hypervisor. It is equipped with an Intel Xeon 8124M processor operating at 3.4 GHz, delivering 36 dedicated vCPUs across 18 physical cores. The system includes 96.0 GB of DDR4 memory at 3 GHz, but lacks local storage and GPU hardware. It features a baseline network bandwidth of 50 Gbps. Benchmark data indicates average performance across most metrics, including a multi-core stress-ng score of 33340.81 and a static web serving throughput of 21.71 GB/sec. However, a notable tradeoff is observed in large-scale language model inference, where prompt processing for a 70B model falls to a poor 5.27 tokens per second. This instance is suited for network-intensive compute tasks, software compilation, and database operations that do not require local SSD storage or GPU acceleration.
