      CPU and System Topology

      Server Description

      An arm64 compute-optimized server featuring sixty-four dedicated cores and high memory bandwidth for demanding multi-threaded and database workloads.

      Compute OptimizedGeneral Purpose

      Alibaba Cloud ecs.c8y.16xlarge is an arm64 compute-optimized server powered by a 64-core Alibaba YiTian710 processor running at 2.75 GHz. It features 128.0 GB of RAM, providing a 1:2 vCPU-to-memory ratio, and lacks local storage and GPU hardware. The instance delivers 32 Gbps of baseline network bandwidth. In benchmark testing, the server demonstrates strong multi-core capabilities, including a multi-core stress-ng score of 114685.05 and a top-tier PassMark memory score of 3017.93. Database performance is also strong, highlighted by 94.6 million operations per second in Redis SET tests. With its dedicated arm64 cores and high memory bandwidth, this instance is configured for multi-threaded workloads, database operations, and web serving, offering a resource-dense profile without the overhead of local storage.

      Workload Profiles

      3.05Score
      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.
