      Server Description

      An x86 memory-optimized instance featuring high-speed DDR5 memory and dedicated Intel Xeon processing for memory-intensive enterprise workloads.

      Memory OptimizedGeneral Purpose

      Amazon Web Services r7i.4xlarge is a memory-optimized instance featuring 16 vCPUs (8 physical cores) powered by an Intel Xeon 8488C processor running at 3.2 GHz. Built on the AWS Nitro hypervisor, it delivers 128.0 GB of 5 GHz DDR5 memory, establishing an 8.0 GB per core ratio. The instance lacks local storage and dedicated GPUs, relying on a 6 Gbps baseline network bandwidth. Benchmark results highlight strong single-core performance, with a Geekbench single-core score of 2141.0 and strong single-threaded gzip compression of 33.78 GB/sec. It also supports Intel AMX and AVX-512 instruction sets, facilitating efficient cryptographic and matrix operations. This instance is designed for memory-intensive workloads, such as in-memory databases, caching layers, and data processing tasks that benefit from high memory density and strong single-threaded execution.

      Workload Profiles

      1.3Score
      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.
