    Server Description

    A high-frequency bare-metal platform combining massive memory capacity with local NVMe storage for demanding database and in-memory workloads.

    Memory OptimizedStorage & Database

    Amazon Web Services x8aedz.metal-12xl is a bare-metal, memory-optimized server powered by an AMD EPYC 9R05 x86_64 processor with 48 dedicated physical cores running at 5.0 GHz. It features 1536.0 GB of RAM, providing a high density of 32.0 GB per core, alongside a 3800 GB local NVMe SSD and a 38 Gbps baseline network bandwidth. Lacking GPU hardware, the instance relies on its high-frequency CPU and memory architecture, achieving top-tier performance in multi-core processing, memory bandwidth, and database operations. Benchmark results show 176.61 million Redis SET operations per second and 118.26 GB/sec static web serving throughput. This configuration offers high qualitative cost efficiency for memory-intensive applications without requiring GPU acceleration. It is designed for large-scale in-memory databases, heavy data processing, enterprise database management systems, and high-throughput web serving workloads.

    Workload Profiles

    7.23Score
    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.
