      Server Description

      A memory-optimized virtual server featuring high-speed DDR5 RAM and advanced Intel Xeon processors for memory-intensive enterprise workloads.

      Memory OptimizedGeneral Purpose

      Amazon Web Services r7i.8xlarge is a memory-optimized instance featuring 32 vCPUs and 16 physical cores powered by an Intel Xeon 8488C processor running at 3.2 GHz. It is configured with 256.0 GB of high-speed 5 GHz DDR5 memory, yielding 8.0 GB of RAM per core. The instance operates on the AWS Nitro hypervisor and provides a baseline network bandwidth of 12 Gbps, though it lacks local storage and GPU accelerators. Benchmark results indicate strong single-core capabilities, with top 25% scores in Geekbench single-core and image processing, alongside strong large-block memory write speeds. While small-model LLM inference performs exceptionally well, large-model inference is a notable bottleneck. This instance is suited for memory-intensive applications, in-memory databases, and web serving workloads that require substantial RAM capacity without the need for local physical storage.

      Workload Profiles

      2.19Score
      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.
