    CPU and System Topology

    Server Description

    A dedicated 64-core AMD EPYC processor platform delivering top-tier multi-core performance and high memory bandwidth for compute-intensive enterprise workloads.

    Compute OptimizedGeneral Purpose

    Microsoft Azure F64as_v6 is an x86_64 server from the Fasv6 family, configured with 64 dedicated AMD EPYC 9V74 physical cores running at 3.7 GHz and 256.0 GB of RAM. Operating under Microsoft Hyper-V, this server lacks local storage and GPUs but supports Premium Storage. It delivers top-tier multi-core CPU performance, as evidenced by a PassMark CPU score of 91,536.52 and a stress-ng multi-core score of 196,900.41. Memory performance is strong, with cached read bandwidth reaching 9,339.97 GB/sec. The server is highly effective for multi-threaded tasks, software compilation, and database operations, achieving 132.21 million operations per second on Redis SET benchmarks. It also handles medium-sized language model inference efficiently, processing 7B model prompts at 231.52 tokens per second. This hardware profile is optimized for compute-intensive workloads, web serving, and database applications requiring high-density processing without local storage.

    Workload Profiles

    3.62Score
    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.
