      Server Description

      A memory-optimized ARM64 server delivering top-tier memory bandwidth and high-density RAM for demanding database and caching workloads.

      Memory OptimizedGeneral Purpose

      Amazon Web Services r8gb.8xlarge is a memory-optimized server powered by the 64-bit ARMv9 AWS Graviton Neoverse-V2 processor. It features 32 dedicated physical cores running at 2.8 GHz with no hyperthreading, supported by 256.0 GB of RAM, which provides a high ratio of 8.0 GB of memory per core. The server includes a 67 Gbps baseline network interface, though it lacks local storage and GPU accelerators. In benchmarks, the r8gb.8xlarge delivers top-tier memory bandwidth and database performance, alongside strong multi-core processing capabilities. This hardware profile makes the instance highly efficient for memory-intensive applications. It is particularly suited for in-memory databases, caching layers, and high-throughput web serving workloads that benefit from high memory density and rapid memory access.

      Workload Profiles

      2.66Score
      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.
