      CPU and System Topology

      Server Description

      A memory-optimized virtual machine featuring a high memory-to-core ratio and dedicated Intel Xeon processors for memory-intensive enterprise workloads.

      Memory OptimizedGeneral Purpose

      Microsoft Azure E20_v5 is a memory-optimized virtual machine from the Ev5 family, powered by a 2.8 GHz Intel Xeon 8370C processor with 20 dedicated vCPUs and 10 physical cores. Featuring 160.0 GB of RAM, it provides a high 8.0 GB per vCPU memory density, though it lacks local storage. Performance benchmarks place this instance in the average tier for most tasks, with a single-core Geekbench score of 1623.0 and a multi-core score of 11025.0. It delivers solid database performance, processing 19.7 million Redis SET operations per second, and shows strong text generation speeds of 273.66 tokens/sec on small 135M LLM models. However, prompt processing for large 70B LLM models is poor at 4.16 tokens/sec. This server is suited for memory-intensive applications, relational databases, and caching layers that rely on network-attached storage.

      Workload Profiles

      1.3Score
      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.
