    CPU and System Topology

    Server Description

    An x86_64 memory-optimized configuration featuring high memory density, dedicated AMD EPYC processing, and strong database and multi-core benchmark performance.

    Memory OptimizedGeneral Purpose

    The Microsoft Azure E64as_v5 is an EASv5-family virtual machine featuring 64 dedicated vCPUs and 512.0 GB of RAM, powered by an AMD EPYC 7763 processor running at 3.7 GHz. Built on the x86_64 architecture with Microsoft Hyper-V virtualization, this memory-optimized instance offers a high 1:8 vCPU-to-RAM ratio. It lacks local storage and GPUs but supports Premium Storage. Performance benchmarks place this server in the top 10% for Passmark memory scores and the top 25% for multi-core CPU execution, Redis SET operations, and database operations. Conversely, large-block uncached memory bandwidth and large-model LLM text generation perform in the average and poor tiers, respectively. The server is designed for memory-intensive workloads, including relational databases, in-memory data stores like Redis, and large-scale software compilation, where high memory density and strong multi-core processing are required.

    Workload Profiles

    2.14Score
    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.
