    Server Description

    High-frequency dual-core processing paired with massive DDR5 memory and local NVMe storage for memory-intensive single-threaded workloads.

    Memory OptimizedStorage & DatabaseGeneral Purpose

    Amazon Web Services x8aedz.large is a memory-optimized instance featuring an AMD EPYC 9R05 processor with 2 dedicated physical cores running at 5.0 GHz. It is equipped with 64.0 GB of high-speed DDR5 memory, providing an exceptional 32.0 GB of RAM per core. The instance includes a bundled 158 GB local NVMe SSD for high-speed temporary storage and delivers a baseline network bandwidth of 2 Gbps. Benchmarks indicate top-tier single-core CPU performance and single-threaded compression speeds, though multi-core metrics remain average due to the dual-core design. This hardware profile offers high resource density for memory-heavy, single-thread-bound tasks. It is well-suited for database hosting, caching layers, and text processing workloads.

    Workload Profiles

    0.61Score
    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.
