      CPU and System Topology

      Server Description

      A memory-optimized virtual server delivering high RAM density and dedicated Intel Xeon cores for memory-bound enterprise workloads.

      Memory OptimizedGeneral Purpose

      Alibaba Cloud ecs.r5.2xlarge is a memory-optimized instance featuring 8 dedicated vCPUs and 64.0 GB of RAM, running on an Intel Xeon 8163 processor at 2.5 GHz. Utilizing the KVM hypervisor and x86_64 architecture, it delivers a high memory-to-core ratio of 8.0 GB per core. The instance lacks local storage and GPUs, relying on a baseline network bandwidth of 2 Gbps. Benchmark data shows weak single-core and multi-core CPU performance, alongside poor single-threaded compression speeds. However, it maintains average performance in large-block uncached memory bandwidth (41.01 GB/sec read) and LLM inference for small models. Qualitatively, this instance provides cost-effective memory density for workloads that prioritize RAM capacity over raw processing power. It is best suited for memory-intensive applications such as caching layers, moderate in-memory databases, and general-purpose enterprise workloads with low CPU demands.

      Workload Profiles

      0.387Score
      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.
