      Server Description

      A memory-dense virtual machine pairing top-tier single-core Intel performance with an exceptional 168 GB of RAM for memory-bound workloads.

      Memory Optimized

      Microsoft Azure FX8-4ms_v2 is a memory-intensive virtual machine from the FXmsv2 family, running on the Microsoft Hyper-V hypervisor. It features 4 dedicated vCPUs powered by an Intel Xeon 8573C x86_64 processor clocked at 4.2 GHz with a 260 MB L3 cache. The instance is equipped with an exceptionally high memory capacity of 168.0 GB (42.0 GB per core), though it lacks local storage and GPU accelerators. Benchmarks show top-tier single-core performance, including a Geekbench single-core score of 2351.0 and strong single-threaded compression, contrasted by weak multi-core and uncached memory bandwidth results. This profile offers qualitative cost efficiency for memory-bound workloads by avoiding unnecessary CPU overhead. It is best suited for memory-intensive database operations, in-memory caching, and single-threaded data processing, while being poorly suited for highly parallelized compute tasks.

      Workload Profiles

      0.54Score
      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.
