      Server Description

      An ARM-based compute-optimized instance featuring dedicated physical cores and high network bandwidth for parallelized workloads and web serving.

      Compute OptimizedGeneral Purpose

      Amazon Web Services c6gn.4xlarge is a compute-optimized instance featuring 16 dedicated physical ARM64 cores powered by the AWS Graviton2 Neoverse-N1 processor running at 2.5 GHz. It is equipped with 32.0 GB of system memory, providing 2.0 GB per core, and operates on the AWS Nitro hypervisor with a baseline network bandwidth of 25 Gbps. The instance does not include local storage or GPU accelerators. Performance benchmarks show average multi-core capabilities, including a stress-ng multi-core score of 24284.25 and a Geekbench multi-core score of 8613.0, alongside average static web serving and database performance. However, single-core performance and cryptographic operations are relatively weak. The c6gn.4xlarge is best suited for multi-threaded workloads, software compilation, and network-intensive applications such as static web serving, offering a cost-efficient ARM-based profile for parallelizable tasks.

      Workload Profiles

      0.954Score
      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.
