      CPU and System Topology

      Server Description

      A dedicated 64-core ARM64 platform delivering balanced memory capacity and strong multi-threaded performance for database and web-serving workloads.

      General Purpose

      Alibaba Cloud ecs.g8y.16xlarge is a general-purpose instance powered by the ARM64-based Alibaba YiTian710 processor, featuring 64 dedicated physical cores running at 2.75 GHz and 256.0 GB of RAM. Operating on a KVM hypervisor, this server lacks local storage and GPU acceleration but delivers a baseline network bandwidth of 32 Gbps. Benchmarks show strong multi-core capabilities, with a stress-ng multi-core score of 114,913.22 and a top-tier PassMark memory score of 3,005.05. It also demonstrates strong database performance, executing 93.0 million Redis SET operations per second and scoring 24,564.67 in PassMark database operations. The custom ARM architecture provides high resource density, making this instance a qualitatively cost-efficient choice for multi-threaded workloads, database hosting, static web serving, and parallel data processing.

      Workload Profiles

      2.9Score
      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.
