      CPU and System Topology

      Server Description

      A dedicated AMD EPYC platform delivering balanced compute and memory resources for enterprise applications and multi-threaded workloads.

      General PurposeCompute Optimized

      Alibaba Cloud ecs.g7a.16xlarge is a general-purpose instance featuring 64 dedicated vCPUs and 256.0 GB of RAM, powered by an AMD EPYC 7T83 processor running at 2.55 GHz. Built on the x86_64 architecture, it delivers strong multi-core CPU performance, ranking in the top 25% for software compilation, ray tracing, and database operations. The instance lacks local storage and dedicated GPUs, relying on network-attached storage and a 16 Gbps baseline network bandwidth. While cached memory bandwidth is highly competitive, uncached large-block memory operations perform at average levels. This resource configuration provides balanced compute-to-memory density, making it a viable option for enterprise workloads, multi-threaded applications, and database hosting.

      Workload Profiles

      1.9Score
      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.
