    Server Description

    A compute-optimized instance featuring high-speed DDR5 memory, dedicated Intel Xeon cores, and integrated local NVMe SSD storage.

    Compute OptimizedStorage & Database

    Amazon Web Services c8id.4xlarge is an x86_64 compute-optimized instance featuring an Intel Xeon 6975P-C processor with 16 dedicated vCPUs, 8 physical cores, and a 3.9 GHz clock speed. It is equipped with 32.0 GB of DDR5 memory running at 7 GHz and a 950 GB local NVMe SSD instance store. Operating on the Nitro hypervisor, the instance delivers 8 Gbps of baseline network bandwidth. Benchmark data shows top-tier single-core performance, particularly in text processing and single-threaded compression, alongside strong performance in small-model LLM text generation. The 2.0 GB of memory per core makes it highly efficient for compute-bound tasks, though it may constrain memory-heavy applications. It is best suited for software compilation, database operations, and high-throughput web serving.

    Workload Profiles

    1.6Score
    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.
