      Server Description

      A compute-optimized instance featuring dedicated Intel Xeon processors, high-speed DDR4 memory, and optimized network bandwidth for compute-heavy workloads.

      Compute OptimizedGeneral Purpose

      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.

      Workload Profiles

      0.81Score
      Precomputed compound score for Cache Intensive workloads. A weighted average (geometric mean) of benchmark scores compared to their medians: score = ∏ (x_i / m_i)^(w_i / Σw). The score of 1.0 represents a synthetic baseline server with the median performance of each component benchmark; 0.5 means roughly half the performance; and 2.0 means twice the performance of that reference profile. Component weights: 50% Redis RPS (pipeline=1, SET), 20% Redis RPS (pipeline=16, SET), 10% PassMark Memory Mark (composite), 10% Memory bandwidth (read, 16 MB ~ L3), 10% PassMark single-thread CPU. Rationale for component selection: In-memory key-value store workload, mixing direct Redis performance metrics with memory speed and latency benchmarks, and single-core CPU performance profiles.
