      CPU and System Topology

      Server Description

      A balanced 64-vCPU virtual machine featuring dedicated AMD EPYC processing and 256 GB RAM for demanding multi-threaded enterprise workloads.

      General Purpose

      Microsoft Azure D64as_v6 is a general-purpose virtual machine from the Dav6 family, powered by an AMD EPYC 9V74 processor with 64 dedicated vCPUs and 32 physical cores running at 3.7 GHz. It features 256.0 GB of RAM, translating to a balanced 4.0 GB per core. While it lacks local storage, it supports Premium Storage for external disk attachments. The instance excels in multi-threaded performance, ranking in the top 10% for Geekbench multi-core benchmarks and showing strong results in database operations, Redis SET performance, and software compilation. It supports AVX-512 and cryptographic instructions, making it highly capable for secure, compute-intensive tasks. This server is optimized for general-purpose enterprise applications, web serving, database hosting, and moderate LLM inference workloads.

      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.
