    Server Description

    An x86_64 compute-optimized platform featuring ninety-six virtual cores, integrated NVMe SSD storage, and strong multi-threaded cryptographic performance.

    Compute OptimizedStorage & Database

    Amazon Web Services c5ad.24xlarge is an x86_64 compute-optimized instance featuring 96 vCPUs (48 physical cores) powered by an AMD EPYC 7R32 processor running at 3.3 GHz. It includes 192 GB of DDR4 memory and 3800 GB of local NVMe SSD storage, running on the Nitro hypervisor with 20 Gbps baseline network bandwidth. Benchmark results indicate a tradeoff: single-core CPU performance is in the bottom 10%, whereas multi-core performance is average, and cryptography execution is in the top 10%. The instance also shows strong performance in software compilation, ray tracing, and Redis SET operations. Qualitatively, the bundled local NVMe storage provides cost-efficient high-speed scratch space. This instance is suited for multi-threaded workloads, software compilation, cryptographic processing, and database operations requiring high-speed local storage.

    Workload Profiles

    2.6Score
    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.
