      Server Description

      A memory-optimized virtual server featuring dedicated AMD EPYC processors and high-speed DDR5 memory for memory-intensive workloads.

      Memory OptimizedGeneral Purpose

      Amazon Web Services r7a.xlarge is a memory-optimized instance featuring 4 dedicated AMD EPYC 9R14 vCPUs running at 3.7 GHz and 32.0 GB of high-speed 5 GHz DDR5 memory. Operating on the Nitro hypervisor, it delivers a high memory-to-vCPU ratio of 8.0 GB per core without local storage or GPU accelerators. Benchmark results highlight strong single-core CPU and text processing performance, though uncached large-block memory read bandwidth and medium-model LLM inference are weak. Multi-core performance, database operations, and small-model LLM processing remain average. With a 2 Gbps baseline network bandwidth, this instance is designed for memory-intensive workloads such as Redis caching, in-memory databases, and text processing applications.

      Workload Profiles

      0.442Score
      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.
