      CPU and System Topology

      Server Description

      A dedicated compute-optimized instance featuring thirty-two Intel Xeon vCPUs and forty gigabits per second network bandwidth for CPU-bound workloads.

      Compute OptimizedGeneral Purpose

      Alibaba Cloud ecs.c7nex.8xlarge is an x86_64 compute-optimized instance featuring 32 dedicated vCPUs (16 physical cores) powered by an Intel Xeon 8369B processor running at 2.7 GHz, paired with 64.0 GB of RAM. It lacks local storage and GPU accelerators but provides a baseline network bandwidth of 40 Gbps. Benchmark results place its performance in the average tier, with a multi-core stress-ng score of 31066.87 and a Redis SET throughput of 31.02 million operations per second. The 1:2 vCPU-to-RAM ratio makes it highly cost-efficient for CPU-bound tasks that do not require massive memory footprints. Tradeoffs include the absence of local NVMe drives and GPU hardware. This instance is best suited for compute-intensive workloads such as software compilation, static web serving, and multi-threaded data decompression.

      Workload Profiles

      1.8Score
      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.
