    CPU and System Topology

    Server Description

    A memory-intensive virtual server featuring forty-eight dedicated AMD EPYC cores and high-bandwidth system memory for demanding database workloads.

    Memory OptimizedGeneral Purpose

    Microsoft Azure F48ams_v7 is a memory-optimized virtual machine from the Famsv7 family, featuring 48 dedicated vCPUs and 48 physical cores powered by an AMD EPYC 9V45 processor running at 4.5 GHz. Built on the x86_64 architecture and managed via Microsoft Hyper-V, it provides 384.0 GB of RAM, translating to 8.0 GB per core. The server lacks local storage and GPUs but is premium storage capable. In benchmark testing, the F48ams_v7 demonstrates top-tier performance, ranking in the top 10% for stress-ng CPU tests, Passmark database operations, and Redis SET operations, which reach 130.96 million operations per second. It also shows strong memory bandwidth and efficient medium-model LLM inference. This configuration is highly suited for memory-intensive workloads, database management, and in-memory caching.

    Workload Profiles

    3.11Score
    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.
