      CPU and System Topology

      Server Description

      A dedicated ARM64 compute-optimized instance delivering top-tier single-threaded performance and high memory efficiency for intensive processing workloads.

      Compute OptimizedGeneral Purpose

      Amazon Web Services c9g.4xlarge is a compute-optimized instance featuring 16 dedicated ARM64 physical cores powered by the AWS Graviton ARMv9 Neoverse-V3 processor running at 3.3 GHz. Operating under the Nitro hypervisor, it provides 32.0 GB of memory and a baseline network bandwidth of 8 Gbps, with no local storage or GPU accelerators. Benchmarks highlight top-tier single-threaded performance in gzip compression, bzip3 decompression, and Geekbench text processing, alongside strong multi-core capabilities in database operations and static web serving. The dedicated core architecture delivers high compute density and efficiency for parallel processing without hyperthreading. This instance is optimized for compute-intensive workloads, including web serving, text and data processing, database operations, and lightweight machine learning inference.

      Workload Profiles

      2.47Score
      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.
