    Server Description

    A compute-optimized platform featuring dedicated Intel Xeon processors, high-speed local NVMe storage, and strong multi-core performance for intensive workloads.

    Compute OptimizedStorage & Database

    Amazon Web Services c6id.16xlarge is an x86_64 compute-optimized instance featuring 64 vCPUs powered by an Intel Xeon 8375C processor running at 3.5 GHz. It is configured with 128.0 GB of DDR4 memory, 3800 GB of local NVMe SSD storage, and a 25 Gbps baseline network interface. Operating on the Nitro hypervisor, the instance delivers strong multi-core CPU performance, particularly in software compilation, ray tracing, and database operations, as evidenced by top-tier benchmark results. While its 2.0 GB of memory per core presents a tradeoff for memory-heavy tasks, the integrated high-speed NVMe storage and dedicated compute resources make it highly efficient for compute-intensive workloads. It is well-suited for database hosting, static web serving, and CPU-based machine learning inference.

    Workload Profiles

    2.7Score
    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.
