    Server Description

    An ARM64 compute-optimized platform featuring dedicated physical cores, high-speed local NVMe storage, and top-tier multi-threaded and database performance.

    Compute OptimizedStorage & Database

    Amazon Web Services c8gd.16xlarge is an ARM64 compute-optimized instance powered by 64 dedicated AWS Neoverse-V2 physical cores running at 2.8 GHz. It features 128.0 GB of memory, a bundled 3800 GB local NVMe SSD instance store, and 30 Gbps baseline network bandwidth. Benchmark results show top-tier multi-core and memory performance, including 133.11 million operations per second in Redis SET tests and 459.25 GB/sec uncached large-block read memory bandwidth. Single-core performance and text processing sit in the average tier. The 2.0 GB of memory per core presents a tradeoff for memory-bound applications, but the high-speed local storage and compute density make this instance highly efficient for database operations, multi-threaded software compilation, static web serving, and medium-to-large LLM inference workloads.

    Workload Profiles

    4.86Score
    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.
