      CPU and System Topology

      Server Description

      A balanced 64-vCPU general-purpose instance featuring high-frequency AMD EPYC processing for demanding database and compute workloads.

      General PurposeCompute Optimized

      The Microsoft Azure D64as_v7 is a general-purpose server instance powered by a dedicated AMD EPYC 9V45 processor running at 4.5 GHz. Built on the x86_64 architecture under Microsoft Hyper-V, it delivers 64 vCPUs across 32 physical cores and is paired with 256.0 GB of system memory. While it lacks local storage and GPUs, it is Premium Storage capable. Benchmarks highlight top-tier single-core CPU performance and database operations, alongside strong multi-core and memory bandwidth capabilities. The instance is highly efficient for workloads such as database management, static web serving, and CPU-based LLM inference.

      Workload Profiles

      2.7Score
      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.
