      CPU and System Topology

      Server Description

      A 192-core ARM64 bare-metal server engineered for parallel multi-threaded compute workloads, in-memory caching, and fast software compilation.

      Amazon Web Services c9g.metal-48xl is a bare-metal compute-optimized instance equipped with 192 dedicated ARM64 cores on AWS Graviton Neoverse-V3 processors running at 3.3 GHz. It features 384.0 GB of DDR5 memory, 100 Gbps baseline network bandwidth, zero GPUs, and no local disk storage. Benchmark results show top-tier multi-core CPU throughput, high memory bandwidth, and fast performance in software compilation, multi-threaded decompression, static web serving, and Redis key-value workloads. Single-threaded performance and LLM text generation rates remain average to low. The high core count and high bandwidth suit parallel computing, software build farms, and high-throughput web serving.

      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.
