    Server Description

    A compute-optimized x86_64 platform featuring dedicated Intel Xeon processors, high-speed DDR5 memory, and integrated local NVMe SSD storage.

    Compute OptimizedStorage & Database

    Amazon Web Services c8id.12xlarge is an x86_64 compute-optimized instance featuring 48 dedicated vCPUs powered by an Intel Xeon 6975P-C processor running at 3.9 GHz. It is equipped with 96.0 GB of high-speed DDR5 memory and 2850 GB of local NVMe SSD instance storage. Operating on the Nitro hypervisor, the instance delivers 22 Gbps of baseline network bandwidth. Benchmark data highlights top-tier single-core performance, with a Geekbench single-core score of 2,200.0, and strong memory read bandwidth of up to 3,859.38 GB/sec. The processor supports advanced instruction sets like AVX-512 and Intel AMX for accelerated matrix operations. This instance is highly cost-efficient for compute-intensive tasks that benefit from fast local storage, making it well-suited for software compilation, database operations, image processing, and medium-scale language model inference.

    Workload Profiles

    3.69Score
    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.
