      CPU and System Topology

      Server Description

      A dedicated 24-core compute instance designed for parallelized workloads requiring high CPU density with a minimal memory footprint.

      Compute OptimizedGeneral Purpose

      Alibaba Cloud ecs.ic5.6xlarge is an x86_64 compute-focused server instance powered by an Intel Xeon 8163 processor running at 2.5 GHz. It features 24 dedicated physical cores with a 1.0 thread-per-core configuration and 24.0 GB of system memory, resulting in a low 1.0 GB of RAM per core. The instance lacks local storage and GPU accelerators, utilizing an 8 Gbps baseline network bandwidth. Benchmark results show weak single-core performance but average multi-core capabilities, with a PassMark CPU score of 18361.58 and a Geekbench multi-core score of 7777.0. Due to its low memory-to-CPU ratio, the instance is best suited for parallelized, compute-bound workloads with small memory footprints, such as software compilation, multi-threaded decompression, and static web serving, rather than memory-intensive database operations.

      Workload Profiles

      0.907Score
      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.
