      Server Description

      A balanced general-purpose instance featuring high-frequency Intel Xeon processors, DDR5 memory, and advanced matrix acceleration for diverse workloads.

      General PurposeCompute Optimized

      Amazon Web Services m8i-flex.16xlarge is a general-purpose virtual instance powered by the Nitro hypervisor and an Intel Xeon 6975P-C processor. It features 64 vCPUs, 32 physical cores, and 256.0 GB of DDR5 memory running at 7 GHz, yielding a balanced 4.0 GB of RAM per core. The instance lacks local storage and GPU accelerators but provides a 15 Gbps baseline network bandwidth. Performance benchmarks show top-tier results in single-core Geekbench tests, image processing, and static web serving, alongside strong multi-core capabilities in software compilation and database operations. Supported by advanced instruction sets like Intel AMX and AVX-512, it delivers strong performance for LLM inference and cryptographic tasks. This instance is configured for general-purpose workloads, including web serving, database management, and software development.

      Workload Profiles

      4.43Score
      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.
