      Server Description

      A compute-optimized x86_64 instance featuring high network bandwidth and balanced multi-core performance for network-bound workloads.

      Compute Optimized

      The Amazon Web Services c5n.4xlarge is an x86_64 compute-optimized instance powered by the Nitro hypervisor. It features an Intel Xeon 8124M processor running at 3.4 GHz with 16 vCPUs, 8 physical cores, and 42.0 GB of DDR4 memory. Designed for network-heavy workloads, it provides a 15 Gbps baseline network bandwidth but lacks local storage and GPU accelerators. Benchmark data indicates average multi-core performance, with a stress-ng multi-core score of 14808.85, alongside weak single-core performance. Memory bandwidth is moderate, reaching 89.55 GB/sec for large-block reads. This instance is suited for network-bound applications, multi-threaded processing, static web serving, and Redis deployments, though it is less efficient for single-threaded tasks or large-scale language model inference.

      Workload Profiles

      0.8Score
      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.
