    Server Description

    A high-core compute-optimized platform featuring massive local NVMe storage and DDR5 memory for parallel processing and database workloads.

    Compute OptimizedStorage & Database

    Amazon Web Services c8id.96xlarge is an x86_64 compute-optimized instance featuring 384 vCPUs and 192 physical cores powered by an Intel Xeon 6975P-C processor running at 3.9 GHz. It is equipped with 768.0 GB of DDR5 memory at 7 GHz and 22,800 GB of local NVMe SSD storage, alongside a 100 Gbps baseline network. Benchmark results indicate top-tier performance in multi-core CPU execution, memory bandwidth, and database operations, supported by hardware-accelerated instruction sets like AVX-512 and AMX. However, single-core performance is average, and LLM text generation speeds are limited by the absence of dedicated GPUs. This instance is best suited for highly parallelized workloads, large-scale database operations, high-throughput web serving, and software compilation.

    Workload Profiles

    14Score
    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.
