    Server Description

    An x86_64 server combining dedicated AMD EPYC processing, high-capacity DDR4 memory, and local NVMe storage for data-intensive workloads.

    Memory OptimizedStorage & DatabaseGeneral Purpose

    Amazon Web Services f2.12xlarge is an x86_64 server featuring a dedicated 24-core AMD EPYC 7R13 processor running at 3.4 GHz, delivering 48 vCPUs. It is equipped with 512.0 GB of DDR4 RAM, a 1880 GB NVMe SSD, and a 25 Gbps baseline network interface, all managed via the Nitro hypervisor. Benchmark results show strong CPU performance, with stress-ng and PassMark CPU scores ranking in the top 25%. Multi-threaded bzip3 decompression, ray tracing, and image processing also perform in the top tier. Conversely, memory bandwidth and database operations fall into the average range, and LLM text generation for large 70B models is poor, placing in the bottom 10%. This server is suited for memory-intensive workloads, local storage-dependent applications, and general multi-threaded processing, though it presents clear performance tradeoffs for large-scale language model inference.

    Workload Profiles

    1.82Score
    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.
