      Server Description

      An ARM64 memory-optimized virtual server featuring sixteen dedicated cores and a high memory-to-vCPU ratio for memory-intensive enterprise workloads.

      Memory OptimizedGeneral Purpose

      Amazon Web Services r6g.4xlarge is a memory-optimized instance powered by a 16-core AWS Graviton Neoverse-N1 ARM64 processor running at 2.5 GHz. It features 128.0 GB of RAM, yielding an 8.0 GB per core ratio, and runs on the Nitro hypervisor. The instance lacks local storage and GPU accelerators, utilizing a 5 Gbps baseline network connection. Performance benchmarks show average multi-core capabilities, with a stress-ng multi-core score of 24,284.19 and a Geekbench multi-core score of 8,428.0. Memory read bandwidth reaches 946.72 GB/sec for cached small blocks, though single-core performance is relatively weak. Qualitatively, the custom ARM architecture provides a cost-effective alternative for memory-heavy applications compared to traditional x86 platforms. This instance is well-suited for memory-intensive workloads such as Redis caching, database operations, and medium-scale enterprise applications.

      Workload Profiles

      0.92Score
      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.
