      Server Description

      An arm64 memory-optimized instance featuring thirty-two dedicated cores and two hundred fifty-six gigabytes of RAM for memory-intensive enterprise workloads.

      Memory Optimized

      Amazon Web Services r6g.8xlarge is an arm64 memory-optimized instance powered by the AWS Graviton Neoverse-N1 processor running at 2.5 GHz. It features 32 dedicated physical cores, 256.0 GB of RAM (8.0 GB per core), and a baseline network bandwidth of 12 Gbps, with no local storage. Operating on the Nitro hypervisor, the instance delivers average multi-core performance, as evidenced by a Geekbench multi-core score of 11,647.0 and a stress-ng multi-core score of 48,584.84. Memory bandwidth is strong, reaching 165.0 GB/sec for uncached large-block reads, though single-threaded performance remains a relative bottleneck. Qualitatively, the r6g.8xlarge provides a cost-effective option for memory-heavy workloads due to its high memory-to-core ratio on the energy-efficient Graviton architecture. It is best suited for in-memory databases like Redis, database operations, and multi-threaded processing tasks.

      Workload Profiles

      1.51Score
      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.
