      Server Description

      An x86_64 compute-optimized instance featuring high-speed networking and dedicated Intel Xeon processors for network-bound and distributed workloads.

      Compute OptimizedGeneral Purpose

      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.

      Workload Profiles

      1.4Score
      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.
