      CPU and System Topology

      Server Description

      A memory-intensive virtual machine featuring dedicated high-frequency AMD EPYC cores and a dense sixty-four gigabyte memory configuration for memory-bound workloads.

      Memory OptimizedGeneral Purpose

      Microsoft Azure F8-4ams_v7 is an x86_64 memory-intensive virtual machine from the Famsv7 family, powered by a dedicated 4.5 GHz AMD EPYC 9V45 processor. It features 4 physical cores, 4 vCPUs, and 64.0 GB of RAM, providing a high memory density of 16.0 GB per core. The instance lacks local storage and GPUs but is premium storage capable. In benchmarks, it delivers top-tier single-core CPU performance and single-threaded compression speeds, while multi-core metrics and memory bandwidth remain in the average tier. This resource allocation makes the server a cost-effective option for memory-bound workloads that do not require high core counts. It is suited for database operations, caching layers, and single-threaded data processing.

      Performance

      Workload Profiles

      0.46Score
      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.
