    CPU and System Topology

    Server Description

    A high-density, memory-optimized virtual machine featuring dedicated AMD EPYC processing and substantial local storage for demanding database workloads.

    Memory OptimizedStorage & Database

    Microsoft Azure E64as_v4 is a memory-optimized virtual machine powered by a dedicated AMD EPYC 7763 processor with 64 vCPUs and 512.0 GB of RAM. Operating at 3.525 GHz on the x86_64 architecture, this instance features 32 physical cores, 885 GB of local storage, and is premium storage capable. Benchmark results show top-tier memory performance and strong multi-core processing, though uncached memory bandwidth and single-core operations remain average. The server excels in database operations and memory-intensive tasks, achieving 62.62 million Redis SET operations per second and strong multi-threaded decompression. However, without GPU acceleration, it exhibits weak performance for large-scale LLM text generation, averaging 2.76 tokens per second on 70B models. It is highly suited for large databases, in-memory caching, and software compilation.

    Workload Profiles

    2.12Score
    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.
