      CPU and System Topology

      Server Description

      A dedicated ARMv9 compute instance delivering top-tier software compilation, database operations, and static web serving throughput with 32 physical cores.

      Compute OptimizedGeneral Purpose

      Amazon Web Services c9g.8xlarge is a compute-optimized instance utilizing the ARMv9 architecture with 32 dedicated physical cores and 32 vCPUs. Powered by the AWS Graviton Neoverse-V3 processor running at 3.3 GHz, it features 64.0 GB of memory, resulting in 2.0 GB of RAM per core. The instance operates on the Nitro hypervisor, lacks local storage and GPUs, and delivers a baseline network bandwidth of 17 Gbps. Benchmark evaluations show top-tier performance in software compilation, text processing, static web serving, and database operations. It also exhibits strong multi-core CPU capabilities and cached memory bandwidth, though uncached large-block memory operations remain average. This server is suited for workloads requiring dedicated ARM compute resources, such as software compilation, database hosting, web serving, and multi-threaded data processing.

      Workload Profiles

      3.98Score
      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.
