      Server Description

      A memory-optimized instance featuring dedicated AMD EPYC cores and a high memory-to-vCPU ratio for memory-intensive, low-parallelism workloads.

      Memory OptimizedGeneral Purpose

      Amazon Web Services r6a.large is a memory-optimized instance featuring 2 dedicated vCPUs from 1 physical AMD EPYC 7R13 core running at 3.6 GHz, paired with 16.0 GB of DDR4 memory. It lacks local storage and GPUs, relying on the Nitro hypervisor with a 1 Gbps baseline network speed. Benchmarks show strong single-core CPU performance, but multi-core performance and memory bandwidth are weak, placing in the bottom 25% and bottom 10% respectively. Database and Redis operations also score in the bottom 10%. This instance is qualitatively cost-efficient for memory-heavy workloads with low parallel processing demands, such as lightweight caching, basic data processing, and memory-intensive general-purpose applications.

      Workload Profiles

      0.185Score
      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.
