      CPU and System Topology

      Server Description

      A memory-optimized virtual server featuring high-bandwidth RAM, dedicated Intel Xeon processing, and advanced matrix extensions for demanding database workloads.

      Memory OptimizedGeneral Purpose

      The Microsoft Azure E64ns_v6 is a memory-optimized virtual machine from the Env6 family, powered by a 64-vCPU Intel Xeon 8573C processor running at 4.2 GHz on the Microsoft Hyper-V hypervisor. It features 512.0 GB of RAM, providing a high 8.0 GB per vCPU ratio, but lacks local storage and GPUs. The server demonstrates top-tier memory bandwidth, with large-block read speeds reaching 378.82 GB/sec, and strong database performance, as evidenced by a Passmark database score of 30184.35 and 76.16 million Redis SET operations per second. Supported by Intel AMX and AVX-512 instruction sets, it delivers strong multi-threaded performance. The absence of local storage is a key tradeoff, requiring network-attached storage. This configuration is highly suited for memory-intensive databases, caching layers, and enterprise-scale web serving.

      Workload Profiles

      3.5Score
      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.
