      Server Description

      An ARM-powered, memory-optimized instance delivering high-bandwidth memory performance and dedicated physical cores for memory-intensive enterprise workloads.

      Memory OptimizedGeneral Purpose

      Amazon Web Services r8gn.2xlarge is a memory-optimized instance featuring 8 dedicated physical cores powered by the 2.8 GHz AWS Graviton ARMv9 Neoverse-V2 processor. Built on the Nitro hypervisor, it provides 64.0 GB of RAM, establishing an 8.0 GB per core memory-to-vCPU ratio. The instance lacks local storage and GPUs, utilizing a 25 Gbps baseline network bandwidth for external connectivity. Benchmark data highlights top-tier memory performance, with the Passmark memory score ranking in the top 10% and strong single-threaded bzip3 decompression speeds. Conversely, encryption and medium-model LLM prompt processing represent performance trade-offs, scoring in the lower percentiles. This profile makes the r8gn.2xlarge highly suitable for memory-intensive workloads, including Redis caching, database operations, and text processing, where high memory bandwidth and dedicated ARM cores offer qualitative resource efficiency.

      Workload Profiles

      0.908Score
      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.
