    Server Description

    A bare-metal ARM64 server combining 64 dedicated cores with high-capacity local NVMe storage for multi-threaded and high-throughput workloads.

    Compute OptimizedStorage & Database

    Amazon Web Services c6gd.metal is a bare-metal, compute-optimized server featuring 64 dedicated physical cores of the 64-bit ARMv8 AWS Graviton Neoverse-N1 processor running at 2.5 GHz. It is equipped with 128.0 GB of DDR4 memory, 3800 GB of local NVMe SSD storage, and a baseline network bandwidth of 25 Gbps. Benchmark data shows strong multi-core CPU performance, high cached memory bandwidth, and excellent throughput for static web serving and Redis operations, though single-core and LLM text generation performance are relatively weak. This server is designed for multi-threaded workloads, software compilation, and high-throughput database operations requiring fast local storage.

    Workload Profiles

    2.3Score
    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.
