    Server Description

    A memory-optimized server featuring dedicated 5.0 GHz AMD EPYC cores, 768 GB DDR5 RAM, and high-speed local NVMe storage.

    Memory OptimizedStorage & Database

    Amazon Web Services x8aedz.6xlarge is a memory-optimized server featuring 24 dedicated physical cores powered by an AMD EPYC 9R05 processor running at 5.0 GHz. It is equipped with 768.0 GB of high-speed 6 GHz DDR5 memory, providing 32.0 GB of RAM per core, and includes a 1900 GB local NVMe SSD. Operating on the Nitro hypervisor, the instance delivers a baseline network bandwidth of 19 Gbps. Benchmark results place its single-core CPU performance, large-block memory bandwidth, and image processing capabilities in the top 10% of tested servers. While LLM prompt processing for large 70B models falls in the middle 50%, text generation remains highly efficient. This hardware profile is designed for memory-intensive applications, database operations, and high-throughput caching systems.

    Workload Profiles

    4.1Score
    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.
