      Server Description

      A memory-optimized x86_64 platform featuring dedicated AMD EPYC processors and high-speed DDR5 memory for demanding database and caching workloads.

      Memory OptimizedGeneral Purpose

      Amazon Web Services r7a.8xlarge is a memory-optimized instance featuring 32 dedicated physical cores powered by an AMD EPYC 9R14 processor running at 3.7 GHz. It is equipped with 256.0 GB of DDR5 memory operating at 5 GHz, delivering 8.0 GB of RAM per core. Running on the AWS Nitro hypervisor, the instance provides a baseline network bandwidth of 12 Gbps, though it lacks local storage and GPU accelerators. Benchmark results show strong multi-core CPU performance, high memory write bandwidth, and top-tier prompt processing speeds for small language models. It also demonstrates strong capabilities in database operations and Redis SET performance. This hardware profile makes the r7a.8xlarge highly suitable for memory-intensive workloads, including in-memory databases, caching layers, and CPU-based machine learning inference.

      Workload Profiles

      2.1Score
      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.
