      Server Description

      A high-capacity memory-optimized instance featuring sixty-four virtual cores and robust large-block memory bandwidth for demanding enterprise database workloads.

      Memory OptimizedGeneral Purpose

      Microsoft Azure E64s_v4 is a memory-optimized virtual machine featuring 64 vCPUs and 504.0 GB of RAM, running on an Intel Xeon 8370C x86_64 processor at 2.8 GHz. Utilizing Microsoft Hyper-V, it provides 32 physical cores with hyper-threading and a 48 MB L3 cache. The instance lacks local storage and GPUs, relying on Premium Storage. Benchmarks show strong large-block uncached memory bandwidth, with read speeds at 300.14 GB/sec and write speeds at 134.52 GB/sec, alongside high multi-threaded bzip3 decompression performance. Conversely, single-threaded decompression and LLM text generation speeds are relatively weak. This hardware profile is optimized for memory-intensive enterprise applications, large databases, and multi-threaded data processing tasks.

      Workload Profiles

      2.5Score
      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.
