      Server Description

      A high-density, memory-optimized platform featuring dedicated AMD EPYC processors and DDR5 memory for demanding in-memory database and analytical workloads.

      Memory OptimizedCompute Optimized

      Amazon Web Services r7a.32xlarge is a memory-optimized instance featuring 128 dedicated physical cores powered by 3.7 GHz AMD EPYC 9R14 processors on the x86_64 architecture. It is equipped with 1024.0 GB of DDR5 memory running at 5 GHz, delivering 8.0 GB of RAM per core, but contains no local storage or GPUs. Operating on the AWS Nitro hypervisor, the instance provides a baseline network bandwidth of 50 Gbps. Benchmark results place the r7a.32xlarge in the top tier for multi-core CPU performance, memory bandwidth, and Redis SET operations, which reach 246.48 million operations per second. It also excels in LLM prompt processing and software compilation. This high-density hardware profile offers strong qualitative cost efficiency for memory-intensive workloads, making it highly suited for in-memory databases, large-scale data analytics, and enterprise applications.

      Workload Profiles

      6Score
      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.
