      CPU and System Topology

      Server Description

      An ARM64-powered general-purpose instance delivering dedicated multi-core compute and balanced memory capacity for standard enterprise workloads.

      General Purpose

      Alibaba Cloud ecs.g6r.4xlarge is an ARM64 general-purpose server instance featuring 16 dedicated Ampere Altra vCPUs running at 2.8 GHz and 64.0 GB of RAM. Operating on the KVM hypervisor, this instance does not include local storage or GPU accelerators, relying on a 5 Gbps baseline network bandwidth. Benchmark results place the instance in the average tier for multi-core CPU performance (28603.05 in stress-ng) and memory bandwidth (122.26 GB/sec uncached). However, it exhibits weaker performance in single-threaded bzip3 decompression and CPU encryption tests, partly due to the absence of x86 vector extensions like AVX-512. Qualitatively, the ARM64 architecture offers a cost-efficient alternative for multi-core workloads that do not require specialized instruction sets. It is best suited for general-purpose applications, static web serving, Redis caching, and standard database operations.

      Workload Profiles

      0.98Score
      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.
