      CPU and System Topology

      Server Description

      A memory-optimized virtual machine featuring dedicated Intel Xeon processors and high RAM density for memory-intensive enterprise workloads and caching.

      Memory OptimizedGeneral Purpose

      Alibaba Cloud ecs.hfr7.3xlarge is an x86_64 memory-optimized instance featuring 12 dedicated vCPUs from an Intel Xeon 8369HB processor running at 3.3 GHz, paired with 96.0 GB of RAM. Operating on the KVM hypervisor, this instance delivers a high memory-to-vCPU ratio of 8.0 GB per core but lacks local storage and GPU accelerators. Benchmark results indicate average performance, with a Geekbench multi-core score of 6723.0 and a Redis SET throughput of 11.99 million operations per second. However, it exhibits weak performance in complex tasks like 7B LLM inference, which processes at 17.76 tokens/second. This qualitative resource density makes it a cost-efficient choice for memory-bound workloads rather than heavy compute. It is best suited for in-memory databases, caching layers, and general-purpose enterprise applications.

      Workload Profiles

      0.75Score
      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.
