      Server Description

      A memory-intensive server combining a terabyte of RAM with strong single-core performance for specialized database and caching workloads.

      Memory OptimizedStorage & Database

      Microsoft Azure FX48-12ms_v2 is a memory-optimized x86_64 server configured with an Intel Xeon 8573C processor operating at 4.2 GHz. It features 12 dedicated vCPUs across 6 physical cores and an exceptionally large memory allocation of 1008.0 GB, resulting in 84.0 GB of RAM per core. The server lacks local storage and GPU accelerators, representing a clear tradeoff that prioritizes memory capacity over raw compute density. Benchmark data highlights top-tier single-core and text processing performance, alongside strong single-threaded compression speeds, while multi-core metrics remain in the average tier. This resource profile makes the instance highly cost-efficient for memory-bound workloads that do not require massive parallelization. It is best suited for in-memory databases, large-scale caching layers, and enterprise applications requiring a massive memory footprint paired with strong single-core execution.

      Workload Profiles

      1.3Score
      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.
