      CPU and System Topology

      Server Description

      A dedicated 48-core compute-optimized platform featuring high-frequency Intel Xeon processors for parallel processing and multi-threaded workloads.

      Compute OptimizedGeneral Purpose

      Alibaba Cloud ecs.hfc7.12xlarge is a compute-optimized instance featuring 48 dedicated physical cores powered by an Intel Xeon 8369HB processor clocked at 3.3 GHz. It is configured with 96.0 GB of memory, providing a 2.0 GB per core ratio, and contains no local storage or GPU accelerators. Operating on the KVM hypervisor, the instance delivers a baseline network bandwidth of 16 Gbps. Benchmark results indicate strong performance in multi-threaded bzip3 decompression and memory operations, alongside average performance in standard CPU and cryptographic tests. Due to its dedicated CPU allocation and high clock speed, the instance is highly efficient for compute-dense, parallel workloads such as software compilation, static web serving, and CPU-based machine learning inference, though it is constrained by the lack of local storage and a lower memory-to-vCPU ratio.

      Workload Profiles

      1.87Score
      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.
