      Server Description

      An ARM64 memory-optimized instance featuring dedicated physical cores and top-tier memory bandwidth for database and caching workloads.

      Memory Optimized

      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. Operating on the Nitro hypervisor, it provides 64.0 GB of RAM, yielding a high resource density of 8.0 GB per core, with no hyperthreading. The instance lacks local storage and dedicated GPUs but features a 17 Gbps baseline network bandwidth. Benchmark results highlight top-tier memory performance, with PassMark memory scores in the top 10% and strong single-core processing in the top 25%. However, cryptographic operations and LLM inference tasks show weaker relative performance. This hardware profile is suited for memory-intensive applications, database operations, and caching layers like Redis, where high memory bandwidth and dedicated physical cores are critical, rather than compute-heavy cryptographic or machine learning workloads.

      Workload Profiles

      0.938Score
      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.
