      CPU and System Topology

      Server Description

      A cost-effective, fractional GPU instance offering balanced Intel Xeon compute and dedicated acceleration for lightweight graphics and small-scale model inference.

      GPU AcceleratedGeneral Purpose

      Alibaba Cloud ecs.sgn7i-vws-m4.2xlarge is an x86_64 virtual server featuring an Intel Xeon 8369B processor with 8 dedicated vCPUs, 31.0 GB of RAM, and a fractional NVIDIA A10 GPU providing 4 GB of VRAM. Operating on the KVM hypervisor, this instance lacks local storage but delivers a baseline network bandwidth of 3 Gbps. Benchmark data indicates average performance across standard compute and memory tasks, with a stress-ng multi-core score of 15139.35 and Redis SET throughput of 16.98 million operations per second. The fractional GPU offers a cost-efficient entry point for hardware-accelerated tasks, though it exhibits clear performance trade-offs, such as weak inference speeds on medium 7B LLM models (8.13 tokens/sec) compared to small 135M models (198.84 tokens/sec). This instance is best suited for lightweight GPU-accelerated workloads, virtual workstations, image processing, and small-scale model inference.

      Workload Profiles

      0.97Score
      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.
