      Server Description

      A bare-metal, memory-optimized server featuring 192 vCPUs and 1.5 TB of RAM for high-throughput, memory-intensive enterprise workloads.

      Memory OptimizedGeneral Purpose

      Amazon Web Services r6a.metal is a bare-metal, memory-optimized server powered by AMD EPYC 7R13 processors. Utilizing the x86_64 architecture, it delivers 192 vCPUs across 96 physical cores at 3.6 GHz, paired with 1536.0 GB of DDR4 RAM. The instance lacks local storage and GPUs, but provides a 50 Gbps baseline network bandwidth. In benchmark testing, the r6a.metal exhibits top-tier multi-core CPU and memory bandwidth performance, alongside outstanding Redis SET throughput of 183.62 million operations per second. Conversely, single-threaded operations and text processing fall into the average tier. The bare-metal design eliminates virtualization overhead, making it highly resource-dense for memory-intensive applications. This configuration is best suited for large-memory databases, heavy software compilation, and parallel memory-bound enterprise workloads.

      Workload Profiles

      5.2Score
      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.
