      CPU and System Topology

      Server Description

      A memory-optimized virtual server featuring dedicated AMD EPYC processors and high memory density for caching and database workloads.

      Memory OptimizedGeneral Purpose

      Alibaba Cloud ecs.r6a.8xlarge is a memory-optimized instance featuring 32 dedicated physical cores on an x86_64 AMD EPYC 7H12 processor running at 2.6 GHz. Equipped with 256.0 GB of RAM, it delivers a high memory-to-vCPU ratio of 8.0 GB per core. The instance includes no local storage or GPU hardware, and operates with an 8 Gbps baseline network bandwidth. Benchmark data shows average multi-core CPU scaling, PassMark database operations, and Redis SET throughput, though single-core execution and uncached large-block memory bandwidth are relatively weak. This hardware profile makes the instance qualitatively cost-efficient for memory-heavy workloads that do not require high single-threaded performance. It is suited for database hosting, caching layers, and multi-threaded data processing.

      Workload Profiles

      1.04Score
      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.
