      Server Description

      A memory-optimized x86 server featuring sixty-four gigabytes of high-speed DDR5 RAM and advanced Intel matrix extensions for memory-bound workloads.

      Memory OptimizedGeneral Purpose

      The Amazon Web Services r8i.2xlarge is a memory-optimized instance featuring an Intel Xeon 6975P-C processor with 8 vCPUs, 4 physical cores, and a 3.9 GHz clock speed. It is equipped with 64.0 GB of DDR5 memory running at 7 GHz, yielding 8.0 GB of RAM per core, but lacks local storage and dedicated GPUs. Operating on the Nitro hypervisor, the instance supports advanced instruction sets like AVX-512 and AMX. Benchmark results show strong single-core capabilities, including a top-tier Geekbench text processing score of 2958.0, alongside average multi-core and database performance. While memory bandwidth is high, LLM text generation for 7B models is weak at 8.69 tokens per second. This instance is configured for memory-intensive applications such as caching layers, database operations, and text processing, offering qualitative cost efficiency for workloads requiring high memory density without local storage needs.

      Workload Profiles

      0.97Score
      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.
