      CPU and System Topology

      Server Description

      An x86_64 memory-optimized configuration featuring dedicated AMD EPYC processors and high-density RAM for memory-intensive enterprise workloads.

      Memory Optimized

      Microsoft Azure EC48as_cc_v5 is an x86_64 memory-optimized server featuring a dedicated AMD EPYC 7763 processor with 48 vCPUs, 24 physical cores, and a 3.525 GHz clock speed. It is configured with 384.0 GB of RAM, providing 8.0 GB of memory per core, but includes no local storage or GPUs. Benchmarks show strong CPU and encryption performance, with Passmark memory scores reaching the top 10%. However, large-scale LLM text generation is a notable bottleneck, scoring in the bottom 10%. Qualitatively, the server provides high memory density relative to compute resources, presenting a cost-efficient profile for workloads that utilize external premium storage rather than local drives. It is suited for memory-intensive database operations, software compilation, and moderate-scale language model inference.

      Workload Profiles

      1.7Score
      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.
