      CPU and System Topology

      Server Description

      A high-density ARMv9 compute instance delivering 192 dedicated cores and 100 Gbps networking for highly parallelized enterprise workloads.

      Compute OptimizedGeneral Purpose

      Amazon Web Services c9g.48xlarge is a compute-optimized instance powered by 192 dedicated physical cores of the 3.3 GHz AWS Graviton Neoverse-V3 ARMv9 processor. Operating on the arm64 architecture, it features 384.0 GB of RAM and runs on the Nitro hypervisor. The instance lacks local storage and GPUs but provides a 100 Gbps baseline network bandwidth. Benchmarks show top-tier multi-core performance, with a stress-ng multi-core score of 380393.63 and exceptional memory bandwidth, alongside strong database and Redis performance. It is highly cost-efficient for parallelized, compute-heavy workloads. This server is best suited for high-concurrency web serving, multi-threaded data processing, database operations, and medium-model LLM prompt processing.

      Workload Profiles

      15Score
      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.
