      Server Description

      A high-density memory-optimized platform featuring dedicated AMD EPYC processors and DDR5 memory for demanding enterprise databases and memory-intensive computing.

      Memory OptimizedCompute Optimized

      Amazon Web Services r7a.32xlarge is a memory-optimized server instance featuring 128 dedicated physical cores powered by an AMD EPYC 9R14 processor running at 3.7 GHz. It is equipped with 1024.0 GB of DDR5 memory at 5 GHz, delivering 8.0 GB of RAM per core, and operates on the AWS Nitro hypervisor. The instance lacks local storage and GPU hardware, relying on a 50 Gbps baseline network bandwidth. Benchmarks show top-tier multi-core CPU performance and memory bandwidth, alongside strong single-core execution. This profile makes the instance highly effective for in-memory databases, large-scale software compilation, and memory-intensive enterprise applications, though workloads requiring high local disk I/O or GPU acceleration will face architectural tradeoffs.

      Workload Profiles

      6.04Score
      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.
