      CPU and System Topology

      Server Description

      A high-frequency, memory-intensive virtual server featuring massive RAM capacity and top-tier single-core processing performance for demanding enterprise databases.

      Memory OptimizedCompute Optimized

      The Microsoft Azure FX48-24ms_v2 is a memory-optimized virtual machine designed for resource-intensive workloads. Powered by an Intel Xeon 8573C processor running at 4.2 GHz, it delivers 24 vCPUs and 12 physical cores alongside a massive 1008.0 GB of RAM, translating to 42.0 GB of memory per core. The server features top-tier single-core performance, as demonstrated by its Geekbench single-core score of 2356.0 and strong memory write bandwidth of 120.35 GB/sec. While it lacks local storage and dedicated GPUs, it supports Premium Storage and features advanced instruction sets like AVX-512 and Intel AMX. This configuration makes it highly effective for memory-bound applications, including large-scale in-memory databases, complex text processing, and memory-intensive enterprise applications.

      Workload Profiles

      2.2Score
      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.
