    Server Description

    An x86 compute instance combining dedicated AMD EPYC processors with fast local NVMe storage for balanced single-threaded workloads.

    Compute OptimizedStorage & Database

    Amazon Web Services c5ad.xlarge is an x86_64 compute-optimized instance featuring 4 vCPUs and 2 physical cores powered by an AMD EPYC 7R32 processor running at 3.3 GHz. It is configured with 8.0 GB of DDR4 memory and a 150 GB local NVMe SSD instance store. Operating on the AWS Nitro hypervisor, the instance delivers a baseline network bandwidth of 1 Gbps. Benchmark results reveal average performance in single-threaded tasks like gzip compression and Geekbench single-core tests, though multi-threaded CPU and memory bandwidth benchmarks fall into the lower percentiles. The inclusion of dedicated local NVMe storage offsets memory throughput limitations for specific workloads. This instance is suited for applications requiring moderate compute capacity and fast local scratch space, such as lightweight web serving, text processing, and basic database operations.

    Workload Profiles

    0.249Score
    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.
