      CPU and System Topology

      Server Description

      A high-density compute instance featuring 128 dedicated AMD EPYC vCPUs and a streamlined memory profile for intensive parallel processing.

      Compute OptimizedGeneral Purpose

      Microsoft Azure D128als_v7 is a compute-optimized virtual machine powered by a 128-vCPU AMD EPYC 9V45 processor running at 4.5 GHz on the Microsoft Hyper-V hypervisor. Featuring 256.0 GB of RAM, this instance provides a low memory-to-vCPU ratio of 2.0 GB per core, prioritizing raw compute density over memory capacity. It lacks local storage and dedicated GPUs but supports premium remote storage. Benchmark results place the server in the top 10% for single-core and multi-core CPU performance, memory bandwidth, and cryptographic execution. It demonstrates exceptional throughput in Redis operations and static web serving. The D128als_v7 is engineered for compute-intensive workloads, including high-concurrency web serving, CPU-based machine learning inference, and multi-threaded data processing pipelines.

      Workload Profiles

      4.9Score
      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.
