    Server Description

    A memory-optimized server combining dedicated Intel Xeon processors, high-speed DDR5 RAM, and fast local NVMe SSD storage for demanding database workloads.

    Memory OptimizedStorage & Database

    Amazon Web Services r8id.12xlarge is a memory-optimized instance featuring 48 vCPUs and 24 physical cores powered by dedicated Intel Xeon 6975P-C processors running at 3.9 GHz. It is equipped with 384.0 GB of high-speed 7 GHz DDR5 memory and 2850 GB of local NVMe SSD storage. Operating under the Nitro hypervisor, the server delivers a baseline network bandwidth of 22 Gbps. Benchmark data highlights strong performance, including a Geekbench single-core score of 2190.0 and a Redis SET throughput of 85.77 million operations per second. The processor supports advanced vector and matrix extensions, enabling efficient local LLM inference, such as 27.85 tokens per second on 7B models. This hardware profile is designed for memory-intensive databases, high-throughput caching, and data processing workloads requiring fast local storage.

    Workload Profiles

    3.68Score
    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.
