      CPU and System Topology

      Server Description

      An ARM64-powered, memory-optimized instance delivering high memory bandwidth and dedicated core performance for database and caching workloads.

      Memory OptimizedGeneral Purpose

      Alibaba Cloud ecs.r8y.8xlarge is a memory-optimized, ARM64-based instance powered by a 32-core Alibaba Yitian 710 processor running at 2.75 GHz. It features 256 GB of RAM, providing a high 8 GB per core ratio, and operates on a KVM hypervisor with 16 Gbps baseline network bandwidth. The instance does not include local storage or GPU accelerators. Benchmark data highlights strong performance in memory-bound and multi-threaded tasks, including a high Passmark memory score and efficient database operations, alongside average multi-core CPU performance. The custom ARM architecture offers qualitative resource density and cost efficiency compared to traditional x86 platforms. This instance is well-suited for memory-intensive applications, database hosting, multi-threaded data processing, and Redis caching layers.

      Workload Profiles

      1.89Score
      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.
