    Server Description

    A compute-optimized x86_64 platform featuring 128 vCPUs, DDR5 memory, and 7.6 TB of local NVMe SSD storage for multi-threaded workloads.

    Compute OptimizedStorage & Database

    Amazon Web Services c8id.32xlarge is an x86_64 compute-optimized server featuring 128 vCPUs, 64 physical Intel Xeon 6975P-C cores running at 3.9 GHz, and 256.0 GB of DDR5 memory. It includes 7600 GB of local NVMe SSD storage and a 50 Gbps baseline network interface. Operating on the Nitro hypervisor, this instance delivers top-tier multi-core CPU performance, high memory bandwidth, and strong database operation metrics, though its single-core performance remains in the average tier. With a low memory-to-core ratio of 2.0 GB per core, it offers a cost-efficient profile for compute-heavy tasks that leverage its built-in AVX-512 and AMX instructions. It is highly suited for multi-threaded decompression, software compilation, static web serving, and CPU-based LLM prompt processing.

    Workload Profiles

    7.5Score
    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.
