    CPU and System Topology

    Server Description

    A memory-optimized virtual machine featuring dedicated AMD processors, substantial RAM capacity, and high-speed local SSD storage for enterprise workloads.

    Memory OptimizedStorage & Database

    Microsoft Azure EC48ads_v5 is an ECADSv5-family virtual machine featuring 48 dedicated x86_64 vCPUs powered by AMD processors on the Microsoft Hyper-V hypervisor. It provides 384.0 GB of system memory, establishing a high memory-to-core ratio of 8.0 GB per vCPU. The instance includes 1843 GB of local SSD storage and supports Premium Storage, though it lacks onboard GPUs and complimentary public IPv4 addresses. This hardware profile is optimized for memory-intensive workloads, large-scale databases, and enterprise applications requiring substantial memory capacity and fast local storage. The dedicated CPU allocation ensures consistent performance for multi-threaded enterprise tasks, while the local SSD storage provides reliable temporary space for high-throughput operations.

    Workload Profiles

    1.8Score
    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.Partial coverage: missing component benchmark(s): PassMark Memory Mark (composite), Memory bandwidth (read, 16 MB ~ L3), PassMark single-thread CPU.
