    Server Description

    An x86_64 compute-optimized instance featuring dedicated AMD EPYC processors and high-speed local NVMe SSD storage for balanced workloads.

    Compute OptimizedStorage & Database

    Amazon Web Services c5ad.2xlarge is a compute-optimized instance featuring an AMD EPYC 7R32 processor with 8 vCPUs, 4 physical cores, and 16.0 GB of DDR4 memory. Operating on the Nitro hypervisor, this x86_64 instance includes 300 GB of local NVMe SSD storage and a baseline network bandwidth of 2 Gbps. Benchmark data indicates average performance across Geekbench tests, software compilation, and Redis operations, though stress-ng CPU tests and large-block memory bandwidth show weaker results. The instance represents a qualitative balance of dedicated compute resources and fast local storage, making it suitable for workloads like static web serving, moderate database operations, and software development, while its lower memory-to-vCPU ratio presents a tradeoff for memory-intensive applications.

    Workload Profiles

    0.426Score
    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.
