      CPU and System Topology

      Server Description

      A memory-intensive, high-vCPU virtual machine delivering top-tier memory bandwidth and processing power for demanding database and enterprise workloads.

      Memory OptimizedCompute Optimized

      Microsoft Azure F64ams_v7 is a memory-intensive virtual machine from the Famsv7 family, configured with 64 dedicated AMD EPYC 9V45 vCPUs operating at 4.5 GHz and 512.0 GB of RAM. Running on the x86_64 architecture under Microsoft Hyper-V, this server delivers top-tier CPU and memory performance, as evidenced by stress-ng and Passmark benchmarks. It achieves exceptional memory bandwidth and handles up to 170.72 million Redis SET operations per second. However, the server lacks local storage and dedicated GPUs, which limits its efficiency for large-scale 70B LLM inference, where it delivers average performance. This instance is optimized for memory-intensive databases, high-throughput web serving, and CPU-driven enterprise workloads that utilize remote Premium Storage.

      Workload Profiles

      3.8Score
      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.
