      Server Description

      An ARM64 compute-optimized instance featuring thirty-two dedicated physical cores and sixty-four gigabytes of memory for multi-threaded workloads.

      Compute OptimizedGeneral Purpose

      Amazon Web Services c6g.8xlarge is a compute-optimized instance featuring 32 dedicated physical ARMv8 cores powered by the AWS Graviton2 Neoverse-N1 processor running at 2.5 GHz. Built on the Nitro hypervisor, it provides 64.0 GB of memory and 12 Gbps baseline network bandwidth, with no local storage or GPU. Benchmarks show average multi-core performance, with a stress-ng multi-core score of 48574.31 and a Geekbench multi-core score of 11649.0. However, single-core performance is a tradeoff, with Geekbench single-core scoring in the bottom 25%. The instance is suited for multi-threaded workloads like software compilation, static web serving, and database operations that leverage dedicated physical cores, offering a qualitatively cost-efficient ARM-based alternative to traditional x86 hardware for parallelized tasks.

      Workload Profiles

      1.5Score
      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.
