      CPU and System Topology

      Server Description

      A network-optimized, high-vCPU virtual machine featuring advanced vector extensions and balanced memory for demanding database and web workloads.

      General PurposeCompute Optimized

      Microsoft Azure D64ns_v6 is a network-optimized virtual machine from the Dnv6 family, powered by an Intel Xeon 8573C processor. Operating on the x86_64 architecture, it provides 64 dedicated vCPUs across 32 physical cores at 4.2 GHz, paired with 256.0 GB of RAM. The instance lacks local storage but supports Premium Storage. Benchmarks show strong performance in database operations, Redis SET operations at 71.06 million operations per second, and multi-threaded decompression, alongside strong LLM prompt processing enabled by AVX-512 and AMX instructions. However, large-block uncached memory bandwidth is average, and PassMark memory scores are in the lower tier. This server is suited for network-heavy applications, database hosting, static web serving, and CPU-based machine learning inference.

      Workload Profiles

      3Score
      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.
