      Server Description

      A memory-optimized x86_64 server featuring DDR5 memory and advanced matrix extensions for memory-intensive workloads and small-scale inference.

      Memory Optimized

      Amazon Web Services r7i.8xlarge is a memory-optimized instance featuring 32 dedicated vCPUs from an Intel Xeon 8488C processor running at 3.2 GHz, paired with 256.0 GB of 5 GHz DDR5 memory. Operating on the Nitro hypervisor, this x86_64 server lacks local storage and GPUs but provides 12 Gbps baseline network bandwidth. Benchmark data shows average performance in standard CPU and memory tasks, alongside strong results in large-block memory write bandwidth and single-threaded gzip compression. The CPU supports Advanced Matrix Extensions, enabling top-tier text generation speeds for small language models, though performance degrades to weak for large 70B models. This instance is configured for database operations, memory-intensive applications, and small-scale model inference.

      Workload Profiles

      2.1Score
      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.
