      CPU and System Topology

      Server Description

      A memory-optimized virtual machine featuring dedicated AMD EPYC processing and high memory density for memory-bound workloads.

      Memory OptimizedGeneral Purpose

      Microsoft Azure E4as_v6 is an x86_64 virtual machine from the Eav6 family, featuring a dedicated AMD EPYC 9V74 processor running at 3.7 GHz with 2 physical cores and 4 vCPUs. It provides 32.0 GB of RAM, establishing a memory-optimized 1:8 vCPU-to-RAM ratio. The instance lacks local storage and GPUs but supports Premium Storage. Performance benchmarks indicate strong single-core capabilities, with stress-ng and Geekbench single-core scores in the top 25%. Conversely, multi-core performance and memory read bandwidth are weaker, placing in the average and bottom 25% respectively. Database operations and software compilation also show lower relative performance. Qualitatively, the E4as_v6 offers high memory density per vCPU, making it suitable for memory-intensive workloads, caching, and text processing that do not demand intensive multi-threaded compute or high-speed local storage.

      Workload Profiles

      0.36Score
      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.
