Server Description
A compute-optimized instance featuring dedicated Intel Xeon processors, high-speed DDR4 memory, and optimized network bandwidth for compute-heavy workloads.
Amazon Web Services c5n.4xlarge is a compute-optimized instance utilizing the Nitro hypervisor and an x86_64 Intel Xeon 8124M processor. It provides 16 dedicated vCPUs running at 3.4 GHz, paired with 42.0 GB of DDR4 memory at 3 GHz. The instance lacks local storage and GPUs, relying on its 15 Gbps baseline network bandwidth for external storage and network operations. Benchmark results show average tier performance, with a Geekbench multi-core score of 7317.0 and a Passmark CPU score of 15733.02. It processes Redis SET operations at 13.96 million operations per second and delivers 11.58 GB/sec in static web serving. While efficient for compute-bound tasks, software compilation, and network-heavy applications, it exhibits weak performance on medium-sized LLM prompt processing.
