      CPU and System Topology

      Server Description

      A memory-optimized virtual machine featuring high RAM-to-core density and strong single-core performance for memory-bound enterprise workloads.

      Memory OptimizedGeneral Purpose

      Microsoft Azure E8-4as_v5 is an x86_64 memory-optimized virtual machine from the EASv5 family, powered by an AMD EPYC 7763 processor running at 3.7 GHz. It features 4 dedicated vCPUs, 2 physical cores, and 64.0 GB of RAM, providing a high memory-to-core ratio of 16.0 GB per core. The instance does not include local storage or integrated GPUs but is Premium Storage capable. Benchmark data indicates strong single-core CPU performance, though multi-core CPU performance and memory bandwidth fall into the lower percentiles. Single-threaded compression and text processing show average throughput, whereas multi-threaded decompression and database operations are weak. This configuration is qualitatively cost-efficient for memory-intensive, low-concurrency workloads, making it suitable for in-memory caching, relational databases, and text processing tasks that require substantial memory capacity without demanding high multi-threaded compute performance.

      Workload Profiles

      0.28Score
      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.
