      Server Description

      A high-density, memory-optimized virtual machine featuring dedicated AMD EPYC processors, engineered for demanding database workloads and in-memory caching.

      Memory OptimizedCompute Optimized

      Microsoft Azure EC64as_cc_v5 is a memory-optimized virtual machine configured with 64 dedicated vCPUs and 512.0 GB of RAM, delivering a high 8.0 GB per vCPU ratio. Powered by an AMD EPYC 7763 processor running at 3.525 GHz, this x86_64 server leverages 32 physical cores with hyper-threading. It lacks local storage and dedicated GPUs but supports Premium Storage. Benchmarks show strong multi-core CPU execution, high cached memory bandwidth, and excellent database and Redis performance. However, uncached memory bandwidth is average, and large LLM text generation is weak due to the absence of hardware accelerators. This configuration is highly efficient for memory-intensive workloads, database operations, and in-memory caching, while being less suitable for large-scale AI inference.

      Workload Profiles

      2.1Score
      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.
