      CPU and System Topology

      Server Description

      A high-density memory-optimized platform featuring advanced Intel Xeon processing and top-tier memory bandwidth for demanding database workloads.

      Memory OptimizedStorage & DatabaseCompute Optimized

      Microsoft Azure M128-64bs_v3 is a memory-optimized virtual machine from the MBSMediumMemoryv3 family, powered by a 32-core Intel Xeon 8473C processor running at 4.0 GHz. Utilizing the x86_64 architecture under Microsoft Hyper-V, it delivers 64 vCPUs and 1024.0 GB of RAM, providing a high resource density of 16.0 GB of memory per vCPU. While it lacks local storage and GPUs, it is designed for premium block storage integration. Benchmarks highlight top-tier memory bandwidth, reaching 365.6 GB/sec for large-block reads, and exceptional database performance with 35,206.66 PassMark database operations. Supported by Intel AMX and AVX-512 instruction sets, this instance is highly efficient for memory-intensive workloads, including large-scale relational databases, in-memory data stores like Redis, and enterprise data processing.

      Workload Profiles

      4Score
      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.
