      CPU and System Topology

      Server Description

      A memory-optimized virtual machine featuring dedicated AMD EPYC processors and high memory density for demanding enterprise database and caching workloads.

      Memory OptimizedGeneral Purpose

      Microsoft Azure E20as_v5 is an EASv5-family virtual machine configured with 20 dedicated vCPUs and 160.0 GB of RAM, running on an AMD EPYC 7763 processor at 3.525 GHz. Utilizing the Microsoft Hyper-V hypervisor, this x86_64 instance provides a high memory-to-vCPU ratio of 8.0 GB per core, making it highly suitable for memory-intensive applications. It features no local storage but is Premium Storage capable, and lacks bundled GPUs or public IPv4 addresses. Benchmark data shows strong single-core CPU performance and memory scores, alongside average multi-core and memory bandwidth results. However, LLM inference performance on large models is poor due to the absence of hardware accelerators. This instance is best suited for memory-optimized workloads such as database management, in-memory caching, and general-purpose enterprise applications requiring substantial memory capacity without local storage dependencies.

      Workload Profiles

      0.93Score
      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.
