    CPU and System Topology

    Server Description

    A memory-optimized virtual server featuring dedicated Intel Xeon cores and local storage for database and caching workloads.

    Memory OptimizedStorage & DatabaseGeneral Purpose

    Microsoft Azure DC4ds_v3 is a virtual machine in the DDCSv3 family, utilizing the Microsoft Hyper-V hypervisor. It is equipped with a dedicated 2.8 GHz Intel Xeon 8370C processor featuring 4 physical cores and 4 vCPUs on an x86_64 architecture. The instance provides 32.0 GB of RAM, establishing an 8.0 GB per core memory density, alongside 307 GB of local storage with Premium Storage capability. Performance benchmarks generally fall in the average tier, with a Geekbench single-core score of 1646.0 and multi-core score of 5403.0. While it handles database operations and small-model LLM inference reliably, it exhibits performance trade-offs in multi-threaded bzip3 decompression and 7B LLM inference. This server is best suited for memory-optimized workloads, relational databases, and caching applications.

    Performance

    Workload Profiles

    0.55Score
    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.
