      Server Description

      An ARM64 memory-optimized instance featuring dedicated Graviton cores and high-density memory for database and caching workloads.

      Memory OptimizedGeneral Purpose

      Amazon Web Services r8gb.2xlarge is an ARM64 memory-optimized instance powered by an 8-core AWS Graviton Neoverse-V2 processor running at 2.8 GHz. It features 64.0 GB of RAM, providing a high 8.0 GB per core ratio, and operates on the Nitro hypervisor with a baseline network bandwidth of 17 Gbps. The instance lacks local storage and GPU accelerators. Benchmark results highlight top-tier memory performance, with the PassMark memory score in the top 10% and cached read bandwidth reaching 925.36 GB/sec. While CPU performance is average overall, single-threaded bzip3 decompression is strong, though cryptographic performance is weak. This configuration is suited for memory-intensive workloads such as database operations, Redis caching, and memory-bound data processing, offering a balanced, high-density memory profile without the overhead of local storage or specialized accelerators.

      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.
