    Server Description

    High-frequency single-core processing paired with extreme memory density and fast local NVMe storage for memory-intensive workloads.

    Memory OptimizedStorage & Database

    Amazon Web Services x8aedz.xlarge is a memory-optimized instance featuring 4 dedicated vCPUs on an AMD EPYC 9R05 processor running at 5.0 GHz. It is equipped with 128.0 GB of 6 GHz DDR5 memory, providing a high ratio of 32.0 GB per core, and includes a 316 GB local NVMe SSD. Operating on the Nitro hypervisor, the instance delivers top-tier single-core CPU performance, single-threaded compression, and text processing, while multi-core and memory bandwidth benchmarks remain in the average tier. The high memory-to-vCPU ratio offers qualitative cost efficiency for memory-bound applications that do not require high parallel compute scaling. It is well-suited for in-memory databases, caching layers, and memory-intensive data processing workloads.

    Workload Profiles

    1.04Score
    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.
