      Server Description

      An ARM-based, memory-optimized virtual server delivering high memory bandwidth and dedicated physical cores for memory-intensive caching and database workloads.

      Memory OptimizedGeneral Purpose

      Amazon Web Services r8g.xlarge is an ARM64 memory-optimized instance powered by the AWS Neoverse-V2 Graviton processor. It features 4 dedicated physical cores (4 vCPUs) running at 2.8 GHz, paired with 32.0 GB of RAM, yielding 8.0 GB of memory per core. Operating on the Nitro hypervisor, the instance lacks local storage and provides a baseline network bandwidth of 2 Gbps. Benchmarks show strong memory performance, with a Passmark memory score in the top 25% and a read-only small block memory bandwidth of 462.02 GB/sec. Conversely, CPU-bound tasks like encryption perform in the lower percentiles. With its high memory-to-vCPU ratio and average Redis throughput of 8.53 million operations per second, the r8g.xlarge is well-suited for memory-intensive workloads such as caching layers, database operations, and memory-bound data processing, offering a qualitative balance of high memory density and efficient ARM-based compute.

      Workload Profiles

      0.594Score
      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.
