      CPU and System Topology

      Server Description

      An x86_64 memory-optimized configuration featuring high single-core clock speeds and an exceptional memory-to-vCPU ratio for memory-intensive workloads.

      Memory OptimizedGeneral Purpose

      Microsoft Azure F16-4ams_v7 is an x86_64 memory-optimized server powered by a 4.5 GHz AMD EPYC 9V45 processor with 4 dedicated vCPUs and 128.0 GB of RAM. Running on Microsoft Hyper-V, this instance features an exceptionally high memory-to-core ratio of 32.0 GB per vCPU. It does not include local storage or GPUs. Performance benchmarks show top-tier results in single-core CPU execution, single-threaded gzip compression, and small-model LLM text generation. However, multi-core CPU performance, memory bandwidth, and database operations fall into the average tier, while medium-model LLM prompt processing is relatively weak. Qualitatively, the server provides high memory density per vCPU, offering cost-efficient resource allocation for memory-heavy workloads that do not require massive parallel compute. It is suited for memory-intensive databases, caching systems, and single-threaded processing tasks.

      Workload Profiles

      0.48Score
      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.
