      Server Description

      An ARM64 memory-optimized instance delivering high memory density and dedicated physical cores for parallelized, memory-intensive enterprise workloads.

      Memory OptimizedGeneral Purpose

      Amazon Web Services r6g.8xlarge is a memory-optimized instance powered by the ARM64 AWS Graviton2 processor with Neoverse-N1 cores. It features 32 dedicated physical cores running at 2.5 GHz and 256.0 GB of system memory, yielding 8.0 GB of RAM per core. Operating on the AWS Nitro hypervisor, the instance provides 12 Gbps of baseline network bandwidth but lacks local storage and GPU accelerators. Performance benchmarks show average multi-core capabilities and strong memory read bandwidth of up to 1893.45 GB/sec for cached blocks, though single-core performance and text processing represent clear tradeoffs. This profile offers qualitative cost efficiency for memory-intensive, highly parallelized workloads. It is best suited for in-memory databases like Redis, database operations, static web serving, and multi-threaded data processing.

      Workload Profiles

      1.5Score
      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.
