    Server Description

    An x86_64 compute-optimized platform featuring dedicated AMD EPYC processors, integrated high-speed local NVMe storage, and strong memory performance.

    Compute OptimizedStorage & Database

    Amazon Web Services c5ad.8xlarge is an x86_64 compute-optimized instance powered by an AMD EPYC 7R32 processor running at 3.3 GHz. It features 32 dedicated vCPUs, 16 physical cores, and 64.0 GB of DDR4 memory, alongside a bundled 1200 GB local NVMe SSD instance store. Operating on the Nitro hypervisor, it delivers a baseline network speed of 10 Gbps. Benchmarks show a tradeoff: single-core CPU performance is poor, but multi-core execution, software compilation, and database operations achieve average ratings. Notably, its Passmark memory score is strong. The qualitative cost efficiency of this instance is driven by its high-density local NVMe storage combined with a balanced 1:2 memory-to-vCPU ratio. It is suited for multi-threaded compute workloads, static web serving, software compilation, and database applications requiring fast local temporary storage.

    Workload Profiles

    1.2Score
    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.
