      CPU and System Topology

      Server Description

      A dedicated compute-optimized instance featuring high-frequency Intel Xeon processors and a balanced memory-to-core ratio for compute-intensive workloads.

      Compute OptimizedGeneral Purpose

      Alibaba Cloud ecs.hfc7.3xlarge is a compute-optimized instance featuring a dedicated Intel Xeon 8369HB processor with 12 vCPUs and 6 physical cores running at 3.3 GHz. It is configured with 24.0 GB of RAM, providing a 2.0 GB per vCPU ratio, and does not include local storage or GPU hardware. Operating on a KVM hypervisor, the instance delivers stable, mid-range performance across standard benchmarks, including a Geekbench multi-core score of 6834.0 and a Redis SET throughput of 12.13 million operations per second. The processor supports AVX-512 instructions, enhancing vector and cryptographic operations. With a baseline network bandwidth of 4 Gbps, this instance is designed for compute-bound workloads such as web serving, software compilation, and lightweight data processing where local storage is not required.

      Workload Profiles

      0.76Score
      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.
