      CPU and System Topology

      Server Description

      A dedicated AMD EPYC virtual server offering high memory density and strong single-core performance for memory-bound enterprise workloads.

      Memory OptimizedGeneral Purpose

      Alibaba Cloud ecs.r7a-nps1.8xlarge is an x86_64 memory-optimized server instance featuring 32 dedicated vCPUs and 32 physical cores powered by an AMD EPYC 7T83 processor running at 2.55 GHz. It is configured with 256.0 GB of RAM, yielding a high resource density of 8.0 GB per core, while lacking local storage and GPU accelerators. Operating on the KVM hypervisor, the instance delivers 8 Gbps of baseline network bandwidth. Benchmark results highlight strong single-core CPU and memory performance, alongside average multi-core and database execution speeds. This hardware profile is highly cost-efficient for memory-intensive deployments that do not require local NVMe drives. It is recommended for in-memory databases, caching layers, enterprise applications, and data processing workloads.

      Workload Profiles

      1.18Score
      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.
