      Server Description

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

      Memory OptimizedCompute Optimized

      Amazon Web Services r7a.16xlarge is a memory-optimized server instance featuring 64 dedicated physical cores powered by an AMD EPYC 9R14 processor running at 3.7 GHz. Built on the AWS Nitro hypervisor, it includes 512.0 GB of high-speed 5 GHz DDR5 memory, translating to 8.0 GB of RAM per core. The instance does not feature local storage or integrated GPUs, but it provides a baseline network bandwidth of 25 Gbps. Benchmark evaluations place its multi-core CPU performance, small-block cached memory bandwidth, and Redis SET operations in the top 10% tier. It also demonstrates strong performance in Passmark CPU tests and LLM inference. Lacking local storage, it relies on network storage, making it highly suitable for memory-intensive workloads, large databases, in-memory caching, and data processing tasks that benefit from dedicated compute resources and high-speed DDR5 memory.

      Workload Profiles

      3.59Score
      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.
