      Server Description

      An arm64 memory-optimized instance delivering top-tier memory bandwidth and dedicated cores for high-throughput database and in-memory workloads.

      Memory OptimizedStorage & Database

      Amazon Web Services r8g.8xlarge is an arm64 memory-optimized server powered by 32 dedicated physical cores of the AWS Graviton Neoverse-V2 processor running at 2.8 GHz. It features 256.0 GB of RAM, yielding 8.0 GB per core, with no local storage or GPU accelerators. Operating on the Nitro hypervisor, it delivers a baseline network bandwidth of 15 Gbps. Benchmarks show top-tier memory performance, with large-block read bandwidth at 402.49 GB/sec and exceptional database operation scores. While single-core CPU and LLM inference tasks show average to weak performance, its high memory bandwidth and dedicated cores offer excellent qualitative cost efficiency for memory-intensive applications. It is highly suited for in-memory databases like Redis, large-scale database operations, and static web serving.

      Workload Profiles

      3Score
      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.
