    Server Description

    A compute-optimized x86_64 platform featuring high-speed DDR5 memory, integrated NVMe storage, and advanced matrix extensions for intensive processing workloads.

    Compute OptimizedStorage & Database

    Amazon Web Services c8id.16xlarge is an x86_64 compute-optimized server utilizing a dedicated Intel Xeon 6975P-C processor with 64 vCPUs (32 physical cores) and 128.0 GB of DDR5 memory. Operating at 3.9 GHz, the CPU features a 480 MB L3 cache and supports advanced instruction sets including AVX-512 and AMX. The instance is equipped with 3800 GB of local NVMe SSD storage and a 30 Gbps baseline network interface. Benchmarks show top-tier performance in software compilation, image processing, and static web serving, alongside strong multi-core processing and database operations. While it delivers top-tier prompt processing for large language models via CPU-based matrix extensions, text generation speeds remain average due to the absence of dedicated GPUs. This server is configured for compute-intensive applications, software development pipelines, and high-throughput database workloads requiring fast local storage.

    Workload Profiles

    4.51Score
    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.
