      Server Description

      A high-density, memory-optimized virtual machine featuring sixty-four dedicated vCPUs and over five hundred gigabytes of RAM for enterprise workloads.

      Memory OptimizedGeneral Purpose

      Microsoft Azure E64_v4 is an Ev4-family memory-optimized virtual machine featuring 64 dedicated vCPUs and 504.0 GB of RAM. Powered by an Intel Xeon 8272CL processor running at 2.6 GHz, this x86_64 server utilizes Microsoft Hyper-V virtualization to deliver 32 physical cores with Hyper-Threading. The instance lacks local storage and GPU accelerators, making it reliant on network-attached storage. Performance benchmarks highlight strong multi-threaded capabilities, with top-tier results in bzip3 decompression and Passmark database operations. Conversely, single-core performance and LLM text generation speeds remain average to weak. This hardware profile is qualitatively cost-effective for memory-intensive enterprise applications, in-memory databases, and heavy multi-threaded data processing workloads that do not require local NVMe drives.

      Workload Profiles

      2.2Score
      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.
