      CPU and System Topology

      Server Description

      A memory-optimized virtual server with dedicated Intel Xeon processors and high RAM density for demanding database and caching workloads.

      Memory OptimizedGeneral Purpose

      Alibaba Cloud ecs.r7.4xlarge is a memory-optimized instance featuring 16 dedicated vCPUs and 128.0 GB of RAM, powered by an Intel Xeon 8369B processor running at 2.7 GHz. Built on the x86_64 architecture with the KVM hypervisor, it provides 8.0 GB of memory per core but lacks local storage and GPU acceleration. The instance delivers solid mid-range benchmark results, including a Passmark CPU score of 20751.25 and a Redis SET throughput of 15.46 million operations per second. However, it exhibits weaker performance in demanding tasks, such as prompt processing for 7B LLM models. With a baseline network bandwidth of 10 Gbps, this instance is qualitatively cost-effective for memory-intensive workloads. It is best suited for in-memory databases, caching layers, and enterprise applications requiring high memory density without local storage needs.

      Workload Profiles

      1Score
      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.
