    CPU and System Topology

    Server Description

    A memory-optimized, block-storage-capable virtual server featuring sixty-four dedicated vCPUs and strong multi-threaded performance for demanding database workloads.

    Memory OptimizedStorage & Database

    Microsoft Azure E64bs_v5 is an x86_64 memory-optimized server from the EBSv5 family, powered by a 2.8 GHz Intel Xeon 8370C processor. It features 64 dedicated vCPUs (32 physical cores) and 512.0 GB of RAM, yielding a high 8.0 GB per vCPU ratio. Running on the Microsoft Hyper-V hypervisor, the instance lacks local storage but is engineered for high-performance Premium Block Storage. Benchmark data reveals strong multi-core CPU performance, high uncached memory bandwidth, and strong database and Redis throughput. Conversely, single-core metrics and large-scale LLM text generation represent performance tradeoffs, with the latter dropping to 2.76 tokens per second on a 70B model. This configuration is suited for memory-intensive databases, caching layers, software compilation, and high-throughput web serving.

    Workload Profiles

    3.17Score
    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.
