      CPU and System Topology

      Server Description

      A memory-optimized virtual machine featuring sixty-four high-frequency AMD cores and half a terabyte of RAM for demanding database workloads.

      Memory OptimizedGeneral Purpose

      Microsoft Azure E64as_v7 is an Easv7-family virtual machine featuring 64 dedicated vCPUs and 512.0 GB of RAM, establishing a memory-optimized 1:8 vCPU-to-RAM ratio. Powered by an AMD EPYC 9V45 processor operating at 4.5 GHz, this x86_64 server utilizes Microsoft Hyper-V virtualization. It does not include local storage or GPUs but is Premium Storage capable. Performance benchmarks place its single-core CPU execution, Passmark database operations, and small-to-medium LLM inference speeds in the top 10% tier, while multi-core performance and memory bandwidth rank in the top 25%. This configuration is highly efficient for memory-intensive workloads, including database management, data compression, and web serving, where local storage is not required. The absence of bundled storage and GPUs optimizes the cost profile for pure memory and compute tasks.

      Workload Profiles

      2.9Score
      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.
