      CPU and System Topology

      Server Description

      A high-density bare-metal platform featuring one hundred ninety-two ARMv9 cores and high-speed DDR5 memory for highly parallelized workloads.

      Compute OptimizedGeneral Purpose

      Amazon Web Services c9g.metal-48xl is a bare-metal, compute-optimized server utilizing 192 dedicated ARMv9 Neoverse-V3 physical cores running at 3.3 GHz. It features 384.0 GB of DDR5 memory, a 96 MB L3 cache, and 100 Gbps baseline network bandwidth, with no local storage or GPUs. Benchmarks show top-tier multi-core CPU performance, software compilation speeds, and memory bandwidth, though single-core performance and LLM text generation speeds are average to poor. The ARM-based architecture provides high resource density and qualitative cost efficiency for highly parallelized workloads. Tradeoffs include the lack of local storage and x86 instruction sets like AVX. It is best suited for multi-threaded applications, high-throughput web serving, Redis databases, and large-scale compilation tasks.

      Workload Profiles

      15.4Score
      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.
