      CPU and System Topology

      Server Description

      A compute-optimized x86_64 server featuring eight dedicated Intel Xeon vCPUs and sixteen gigabytes of RAM for compute-focused workloads.

      Compute Optimized

      Alibaba Cloud ecs.c4.2xlarge is an x86_64 compute-optimized instance powered by a 3.2 GHz Intel Xeon 8369HB processor. It features 8 dedicated vCPUs across 4 physical cores, 16.0 GB of RAM, and no local storage, operating on a KVM hypervisor with a baseline network bandwidth of 3 Gbps. The CPU supports AVX-512 extensions but lacks AMX. Performance benchmarks indicate average capabilities for standard CPU tasks, with a Geekbench multi-core score of 4720.0 and Redis SET operations reaching 8.09 million operations per second. However, memory-intensive operations show weaknesses, with uncached large-block read bandwidth at 37.74 GB/sec and a weak Passmark database score of 2280.27. This instance is suited for compute-focused workloads with moderate memory requirements, such as software compilation, static web serving, and basic text processing, while showing performance tradeoffs in memory-bound or large-model inference tasks.

      Workload Profiles

      0.52Score
      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.
