      Server Description

      A single-core, memory-optimized instance featuring dedicated AMD EPYC performance and high-speed DDR5 memory for lightweight, memory-intensive workloads.

      Memory OptimizedGeneral Purpose

      Amazon Web Services r7a.medium is a memory-optimized instance powered by a single dedicated AMD EPYC 9R14 processor core running at 3.7 GHz. Built on the x86_64 architecture and the Nitro hypervisor, it features 8.0 GB of high-speed 5 GHz DDR5 memory, providing a high 1:8 vCPU-to-RAM ratio. The instance does not include local storage or GPU accelerators. Benchmarks show strong single-core CPU performance, though multi-core and memory read bandwidth metrics are lower due to the single-vCPU limitation. This server is qualitatively cost-effective for small-scale, memory-intensive workloads, such as lightweight database operations, single-threaded data processing, and Redis caching, where dedicated CPU allocation and modern DDR5 memory are required without the cost of larger multi-core configurations.

      Workload Profiles

      0.157Score
      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.
