      CPU and System Topology

      Server Description

      An x86 memory-optimized instance featuring dedicated AMD EPYC processors and a high memory-to-vCPU ratio for memory-intensive workloads.

      Memory OptimizedGeneral Purpose

      Alibaba Cloud ecs.r7a.2xlarge is a memory-optimized instance featuring 8 dedicated vCPUs powered by an AMD EPYC 7T83 processor running at 2.55 GHz, paired with 64.0 GB of RAM. Operating on the KVM hypervisor, this x86_64 instance lacks local storage and GPUs, and provides a baseline network bandwidth of 2 Gbps. Benchmarks show strong single-core CPU performance, though large-block uncached memory bandwidth and database operations fall into the lower tier. The instance offers a cost-efficient profile for memory-heavy workloads that do not require local NVMe storage. It is suitable for Redis caching, static web serving, and general-purpose memory-intensive tasks.

      Workload Profiles

      0.408Score
      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.
