    CPU and System Topology

    Server Description

    A dedicated 44-core high-memory instance with RDMA networking designed for parallel computing, database operations, and memory-bound scientific workloads.

    Memory OptimizedCompute OptimizedStorage & Database

    Microsoft Azure HC44rs is an HCS-family high-performance computing instance designed for memory-intensive and parallel workloads. Powered by an Intel Xeon 8168 processor on the x86_64 architecture, it delivers 44 dedicated physical cores and 44 vCPUs at 2.7 GHz, paired with 352.0 GB of RAM (8.0 GB per core) and 717 GB of local storage. The instance is RDMA-capable and supports Premium Storage. Benchmarks show strong multi-core CPU performance, high memory read bandwidth, and excellent throughput in software compilation and Redis operations. However, single-threaded performance is average, and text generation for large language models is poor due to the absence of a GPU. The HC44rs is highly suited for clustered HPC simulations, large-scale databases, and parallel processing workloads where high memory bandwidth and dedicated physical cores are critical.

    Workload Profiles

    2.57Score
    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.
