      CPU and System Topology

      Server Description

      An x86_64 memory-optimized virtual machine featuring a high memory-to-core ratio and strong single-core performance for memory-intensive enterprise workloads.

      Memory OptimizedGeneral Purpose

      Microsoft Azure EC8as_cc_v5 is a memory-optimized virtual machine featuring 8 dedicated vCPUs and 64.0 GB of RAM, yielding a high 8.0 GB of memory per core. Powered by an AMD EPYC 7763 processor running at 3.525 GHz on the Microsoft Hyper-V hypervisor, this x86_64 server lacks local storage and integrated GPUs but supports Premium Storage. Benchmark data highlights strong single-core CPU performance, alongside average multi-core execution, software compilation, and memory read bandwidth. Conversely, uncached large-block write memory bandwidth and medium-model LLM inference represent performance trade-offs, landing in the lower percentiles. Qualitatively, the instance provides a balanced, memory-dense profile without the added cost of local NVMe drives. It is best suited for memory-intensive workloads such as database operations, Redis caching, and general-purpose enterprise applications.

      Workload Profiles

      0.45Score
      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.
