    Server Description

    A compute-optimized instance featuring high-frequency Intel Xeon processors, DDR5 memory, and high-capacity local NVMe SSD storage for demanding workloads.

    Compute OptimizedStorage & DatabaseGeneral Purpose

    Amazon Web Services c8id.12xlarge is a compute-optimized instance featuring 48 vCPUs and 24 physical cores powered by an Intel Xeon 6975P-C processor running at 3.9 GHz. Built on the Nitro hypervisor, it includes 96.0 GB of high-speed DDR5 RAM and 2850 GB of local NVMe SSD storage. The x86_64 architecture supports advanced instruction sets like AVX-512 and Intel AMX, which contribute to strong benchmark results, including a Geekbench multi-core score of 19875.0 and top-tier performance in image and text processing. With a baseline network bandwidth of 22 Gbps and strong memory read bandwidth of 194.95 GB/sec for large uncached blocks, this instance is well-suited for compute-heavy applications, software compilation, high-throughput web serving, and database workloads.

    Workload Profiles

    3.8Score
    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.
