      Server Description

      An arm64 compute-optimized instance delivering dedicated physical cores and high-speed network bandwidth for multi-threaded workloads.

      Compute OptimizedGeneral Purpose

      The Amazon Web Services c6gn.8xlarge is an arm64 compute-optimized instance powered by a 32-core AWS Graviton Neoverse-N1 processor running at 2.5 GHz. It features 32 dedicated vCPUs with no hyperthreading, 64.0 GB of system memory, and a 50 Gbps baseline network bandwidth. Lacking local storage and GPU accelerators, the instance relies entirely on network-attached storage. Benchmark results show average multi-core performance, with a stress-ng multi-core score of 48563.42 and a Geekbench multi-core score of 11689.0, alongside average static web serving throughput of 33.08 GB/sec. Conversely, single-core performance and memory bandwidth for large blocks are relatively weak. This instance is qualitatively cost-efficient for network-heavy, multi-threaded workloads such as static web serving, software compilation, and distributed database operations.

      Workload Profiles

      1.51Score
      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.
