      CPU and System Topology

      Server Description

      A dedicated AMD EPYC platform delivering balanced compute and top-tier memory performance for enterprise databases and caching.

      General Purpose

      Alibaba Cloud ecs.g8a.12xlarge is a general-purpose server instance powered by an AMD EPYC 9T24 x86_64 processor with 48 dedicated physical cores and 48 vCPUs running at 2.7 GHz. Equipped with 192.0 GB of RAM, it maintains a balanced 4.0 GB of memory per core. The instance features no local storage or GPU accelerators, relying on network storage and offering a baseline network bandwidth of 16 Gbps. Performance benchmarks place this instance in the top 25% for both single-core and multi-core CPU execution, with its Passmark memory score reaching the top 10% tier. It is highly efficient for multi-threaded decompression, database operations, and Redis caching, making it an optimal choice for balanced enterprise workloads requiring dedicated compute resources without local storage overhead.

      Workload Profiles

      1.99Score
      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.
