      CPU and System Topology

      Server Description

      An ARM64 compute-optimized instance delivering high-density dedicated cores and top-tier memory bandwidth for parallelized workloads.

      Compute OptimizedGeneral Purpose

      Amazon Web Services c8g.12xlarge is a compute-optimized instance powered by 48 dedicated physical cores of the ARM64 AWS Neoverse-V2 processor running at 2.8 GHz. Operating on the Nitro hypervisor, it features 96.0 GB of RAM, providing a 2.0 GB per core ratio, and delivers a baseline network bandwidth of 22 Gbps. The instance lacks local storage and GPU accelerators. Benchmarks highlight top-tier multi-core capabilities, software compilation speeds, and memory bandwidth, alongside average single-core performance. This hardware profile offers high resource density and qualitative cost-efficiency for multi-threaded tasks. It is highly suited for database operations, static web serving, software compilation, and parallelized compute workloads.

      Workload Profiles

      3.9Score
      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.
