      CPU and System Topology

      Server Description

      A high-density, memory-optimized virtual machine featuring 128 vCPUs and one terabyte of RAM for demanding enterprise database workloads.

      Memory OptimizedGeneral Purpose

      Microsoft Azure E128as_v7 is a memory-optimized virtual machine from the Easv7 family, powered by a dedicated AMD EPYC 9V45 processor. Utilizing the x86_64 architecture, it provides 128 vCPUs (64 physical cores) running at 4.5 GHz and 1024.0 GB of RAM, establishing a high-density 8.0 GB per vCPU ratio. The instance lacks local storage and GPUs but supports Premium Storage. Benchmarks place this server in the top 10% for both single-core and multi-core CPU performance, memory bandwidth, and database operations. It also demonstrates strong capabilities in CPU-based LLM inference and high-throughput web serving. The E128as_v7 is highly suited for memory-intensive enterprise applications, large-scale in-memory databases, and complex data processing pipelines.

      Workload Profiles

      4.9Score
      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.
