      CPU and System Topology

      Server Description

      An ARM64 compute-optimized instance featuring dedicated physical cores and balanced memory bandwidth for efficient web serving and compilation workloads.

      Compute OptimizedGeneral Purpose

      The Amazon Web Services c8g.2xlarge is an ARM64-based, compute-optimized server instance powered by an 8-core AWS Graviton Neoverse-V2 processor running at 2.8 GHz. It features 16.0 GB of RAM, providing a 2.0 GB per vCPU ratio, and operates on the Nitro hypervisor with a 4 Gbps baseline network bandwidth. The instance does not include local storage or GPU accelerators. In benchmark evaluations, the c8g.2xlarge delivers average performance across most compute and memory metrics, highlighted by strong single-threaded bzip3 decompression speeds. However, it exhibits weaker results in CPU encryption and medium-model LLM prompt processing. This instance is qualitatively cost-efficient for dedicated ARM64 compute tasks, making it suitable for workloads such as software compilation, static web serving, Redis deployments, and general-purpose microservices that do not require high memory-to-CPU ratios or local storage.

      Workload Profiles

      1Score
      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.
