      Server Description

      A high-capacity memory-optimized platform featuring 128 virtual cores and one terabyte of RAM for demanding enterprise database workloads.

      Memory OptimizedGeneral Purpose

      Amazon Web Services r6a.32xlarge is a memory-optimized instance featuring 128 vCPUs powered by AMD EPYC 7R13 processors running at 3.6 GHz. It is equipped with 1024.0 GB of DDR4 memory, providing 8.0 GB of RAM per core, and operates on the AWS Nitro hypervisor with 50 Gbps of network bandwidth. Benchmarks show top-tier multi-core CPU performance and memory bandwidth, alongside strong database execution capabilities, such as processing 136.38 million Redis SET operations per second. However, the instance lacks local storage and GPU acceleration, requiring network-attached storage. This server is highly efficient for memory-intensive enterprise workloads, including large-scale in-memory databases, big data analytics, and high-throughput web serving.

      Workload Profiles

      3.9Score
      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.
