    Server Description

    A high-density memory-optimized virtual machine featuring sixty-four dedicated AMD EPYC vCPUs and five hundred twelve gigabytes of system RAM.

    Memory OptimizedGeneral Purpose

    The Microsoft Azure E64as_v6 is an x86_64 memory-optimized virtual machine from the Eav6 family, featuring 64 dedicated vCPUs (32 physical AMD EPYC 9V74 cores) running at 3.7 GHz and 512.0 GB of RAM. Lacking local storage and GPUs, this Premium Storage-capable instance is designed for external storage attachment. Benchmarks highlight top-tier multi-core performance, with a Geekbench multi-core score in the top 10% and strong memory write bandwidth of 108.95 GB/sec. It also excels in cryptography and database operations, as evidenced by a Redis SET throughput of 88.78 million operations per second. The E64as_v6 is qualitatively cost-efficient for memory-heavy workloads, making it highly suitable for enterprise databases, in-memory analytics, and large-scale software compilation.

    Workload Profiles

    2.75Score
    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.
