    CPU and System Topology

    Server Description

    A memory-dense virtual server featuring dedicated AMD EPYC processing and local SSD storage for memory-bound, single-threaded workloads.

    Memory OptimizedStorage & Database

    Microsoft Azure E8-4as_v4 is an x86_64 memory-optimized server from the EASv4 family, powered by a dedicated AMD EPYC 7763 processor running at 3.35 GHz. It is configured with 4 vCPUs, 2 physical cores, 64.0 GB of RAM, and a 131 GB local SSD. Operating under the Microsoft Hyper-V hypervisor, this Premium Storage capable instance exhibits strong single-core CPU performance, ranking in the top 25% in stress-ng benchmarks. However, its multi-core CPU performance, database operations, and write memory bandwidth fall into the bottom 25%. With a high memory-to-vCPU ratio of 16 GB per core, the server provides qualitative cost efficiency for memory-heavy workloads that do not demand high parallel compute scaling. It is best suited for memory-bound applications, caching systems, and single-threaded data processing.

    Workload Profiles

    0.28Score
    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.
