    Server Description

    An ultra-high-density memory instance pairing a high-frequency Intel Xeon processor with over one terabyte of RAM for memory-bound enterprise workloads.

    Memory OptimizedCompute Optimized

    The Microsoft Azure FX64-16ms_v2 is a highly memory-optimized server from the FXmsv2 family, built on the x86_64 architecture. It features a dedicated Intel Xeon 8573C processor operating at 4.2 GHz with 8 physical cores and 16 vCPUs. The defining characteristic of this instance is its massive 1344.0 GB of RAM, yielding an unusually high 84.0 GB of memory per vCPU. While it lacks local storage and complimentary public IPv4 addresses, it is Premium Storage capable. Benchmark data highlights top-tier single-core and text processing performance, alongside strong large-block write memory bandwidth and single-threaded compression speeds. This server offers qualitative cost efficiency for memory-bound workloads by avoiding the need to provision excess vCPUs to obtain high memory capacity. It is best suited for large in-memory databases, caching layers, and memory-intensive enterprise applications.

    Workload Profiles

    1.66Score
    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.
