      CPU and System Topology

      Server Description

      A memory-optimized virtual server featuring dedicated AMD EPYC processors and high memory density for database and caching workloads.

      Memory OptimizedGeneral Purpose

      Microsoft Azure EC16as_cc_v5 is an x86_64 memory-optimized server featuring 16 dedicated vCPUs and 128.0 GB of RAM, powered by an AMD EPYC 7763 processor running at 3.525 GHz. This virtual machine lacks local storage and dedicated GPUs but is Premium Storage capable. Performance benchmarks reveal strong single-core CPU execution and high PassMark memory scores, though multi-core processing and uncached large-block memory write bandwidth are average to weak. Cryptographic tasks benefit from hardware-accelerated AES, VAES, and SHA_NI instructions. With an 8.0 GB per core memory allocation, this server provides a resource-dense profile without the added cost of local NVMe drives. It is suited for memory-intensive workloads such as relational databases, Redis caching, and enterprise application hosting.

      Workload Profiles

      0.72Score
      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.
