    Server Description

    An ARM64 compute-dense platform featuring integrated NVMe storage, exceptional memory bandwidth, and strong multi-threaded database performance.

    Compute OptimizedStorage & Database

    Amazon Web Services c8gd.16xlarge is an ARM64 compute-optimized server featuring 64 dedicated physical cores on the AWS Graviton Neoverse-V2 processor running at 2.8 GHz. It is configured with 128.0 GB of RAM, 3800 GB of local NVMe SSD storage, and a 30 Gbps baseline network interface managed by the Nitro hypervisor. Benchmark data shows top-tier multi-core performance, particularly in software compilation, multi-threaded decompression, and memory bandwidth. Database operations are highly efficient, with Redis SET throughput reaching 133.11 million operations per second. While single-core performance is average, the server's high core density and integrated high-speed local storage make it highly effective for parallel processing, database hosting, static web serving, and medium-scale language model inference.

    Workload Profiles

    4.89Score
    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.
