      CPU and System Topology

      Server Description

      A dedicated 48-core AMD EPYC server delivering top-tier CPU performance and high memory bandwidth for intensive computational workloads.

      Compute OptimizedGeneral Purpose

      Microsoft Azure F48as_v7 is a dedicated x86_64 server from the Fasv7 family, featuring 48 AMD EPYC 9V45 physical cores operating at 4.5 GHz. It is equipped with 192.0 GB of RAM (4.0 GB per core) and operates on the Microsoft Hyper-V hypervisor. The server lacks local storage and GPUs but is Premium Storage capable. Benchmark data indicates top-tier CPU performance, with a stress-ng multi-core score of 176853.77 and a PassMark CPU score of 98684.41. Memory performance is strong, with a large-block write bandwidth of 177.67 GB/sec. While it excels in database operations and small-model LLM inference, processing speeds drop to average levels for larger 70B models. This server is suited for compute-heavy workloads, database management, and web serving.

      Workload Profiles

      3.1Score
      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.
