      Server Description

      An ARM64 compute-optimized server featuring dedicated physical cores, high-speed memory bandwidth, and 50 Gbps baseline network performance.

      Compute OptimizedGeneral Purpose

      Amazon Web Services c8gn.4xlarge is a compute-optimized instance utilizing the 64-bit ARMv9 architecture with an AWS Graviton Neoverse-V2 processor. It delivers 16 dedicated physical cores and 16 vCPUs at 2.8 GHz, paired with 32.0 GB of RAM. The server lacks local storage and GPUs, relying on a 50 Gbps baseline network interface. Benchmark data highlights top-tier memory performance and strong database operations, though CPU-intensive stress tests and medium-sized LLM prompt processing show average to weak results. This instance is suited for network-bound workloads, database operations, and memory-intensive compute tasks where ARM-native execution is preferred.

      Workload Profiles

      1.7Score
      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.
