      Server Description

      A dedicated 16-core ARM64 compute instance delivering balanced multi-threaded performance and high memory bandwidth for containerized workloads.

      Compute OptimizedGeneral Purpose

      Amazon Web Services c6g.4xlarge is a compute-optimized instance running on the AWS Nitro hypervisor and powered by a 64-bit ARMv8 AWS Graviton processor. It features 16 dedicated physical cores (16 vCPUs) at 2.5 GHz, 32.0 GB of RAM, and a 5 Gbps baseline network bandwidth, with no local storage or GPU. Benchmarks show average multi-core performance, with a stress-ng multi-core score of 24286.42 and a Geekbench multi-core score of 8581.0, though single-core performance is weaker. The instance delivers solid results for database operations and web serving, achieving 19.74 million Redis SET operations per second and 18.73 GB/sec static web serving throughput. It offers a cost-efficient option for multi-threaded workloads, software compilation, and containerized microservices, while being less suited for single-threaded tasks or large language model inference.

      Workload Profiles

      0.91Score
      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.
