      CPU and System Topology

      Server Description

      A dedicated twelve-core compute instance designed for parallelized workloads requiring minimal memory overhead and steady multi-threaded performance.

      Compute OptimizedGeneral Purpose

      Alibaba Cloud ecs.ic5.3xlarge is an x86_64 compute-focused server instance featuring 12 dedicated Intel Xeon 8163 vCPUs running at 2.5 GHz and 12.0 GB of RAM. Lacking local storage and GPU hardware, it operates on a KVM hypervisor with a baseline network bandwidth of 4 Gbps. Benchmarks indicate average multi-core performance, software compilation, and static web serving capabilities, contrasted by weak single-core CPU and memory performance. With a strict 1:1 vCPU-to-RAM ratio, this instance offers a cost-efficient profile for parallelized, compute-heavy workloads that do not demand large memory footprints, such as multi-threaded batch processing, lightweight database operations, and web serving.

      Workload Profiles

      0.529Score
      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.
