      Server Description

      A 64-vCPU general-purpose server featuring DDR5 memory and advanced matrix extensions for accelerated multi-threaded workloads and prompt processing.

      General PurposeCompute Optimized

      Amazon Web Services m8i.16xlarge is a general-purpose server featuring 64 dedicated vCPUs from an Intel Xeon 6975P-C processor running at 3.9 GHz, paired with 256.0 GB of DDR5 memory. Operating on the Nitro hypervisor, this instance lacks local storage and dedicated GPUs but provides a baseline network bandwidth of 30 Gbps. Benchmark data shows top-tier performance in multi-core operations, software compilation, and static web serving, alongside strong memory read bandwidth. Single-core CPU performance and large-block memory writes sit in the average tier, representing a clear tradeoff. The inclusion of Intel Advanced Matrix Extensions enables strong prompt processing speeds for large language models. This server is suited for multi-threaded enterprise workloads, database operations, software compilation, and web serving.

      Workload Profiles

      4.7Score
      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.
