      Server Description

      A high-core, memory-optimized instance featuring top-tier memory bandwidth and advanced Intel Xeon processing for demanding enterprise database workloads.

      Memory OptimizedStorage & Database

      Microsoft Azure M128bs_v3 is a memory-optimized server powered by an Intel Xeon 8473C processor with 128 vCPUs and 1024.0 GB of RAM. Operating on the x86_64 architecture, this instance delivers top-tier memory bandwidth, reaching 9026.27 GB/sec for cached reads and 433.45 GB/sec for uncached reads. While it lacks local storage and GPUs, it supports premium block storage and features advanced CPU instructions like AVX-512 and Intel AMX. Benchmarks highlight exceptional multi-threaded performance, top-tier database operations, and high Redis throughput of 138.25 million operations per second. This profile makes it highly efficient for memory-intensive enterprise applications, large-scale databases, and in-memory caching systems.

      Workload Profiles

      5.8Score
      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.
