      Server Description

      A high-density memory-optimized platform featuring 192 vCPUs and 1.5 TB of RAM for scale-out database and caching workloads.

      Memory OptimizedGeneral Purpose

      Amazon Web Services r6a.48xlarge is a memory-optimized server instance featuring 192 vCPUs and 96 physical cores powered by an AMD EPYC 7R13 processor running at 3.6 GHz. Built on the x86_64 architecture and managed by the Nitro hypervisor, it delivers 1536.0 GB of DDR4 memory at 3 GHz, establishing an 8.0 GB memory-to-vCPU ratio. The instance lacks local storage and GPU hardware, but provides a 50 Gbps baseline network bandwidth. In benchmark testing, the r6a.48xlarge achieves top-tier results in multi-core CPU performance, small-block memory bandwidth, and Redis SET operations, while single-core metrics remain in the average tier. This hardware profile is designed for memory-intensive workloads, large-scale database operations, and in-memory caching applications.

      Workload Profiles

      5.05Score
      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.
