      Server Description

      High-density DDR5 memory and dedicated Intel Xeon processors optimized for memory-intensive enterprise workloads and large-scale database operations.

      Memory OptimizedGeneral Purpose

      Amazon Web Services r7i.16xlarge is a memory-optimized instance featuring 64 vCPUs and 512.0 GB of DDR5 memory. Powered by 3.2 GHz Intel Xeon 8488C processors on the AWS Nitro System, this x86_64 instance delivers strong memory bandwidth, reaching 216.54 GB/sec for large uncached blocks. It lacks local storage and GPUs but offers 25 Gbps baseline network bandwidth. Benchmarks show strong capabilities in database operations and memory-bound tasks, making it highly suitable for in-memory databases, caching layers, and enterprise applications.

      Workload Profiles

      3.56Score
      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.
