      Server Description

      An x86_64 general-purpose instance featuring 48 Intel Xeon vCPUs and 192 GB DDR5 RAM for balanced compute and memory workloads.

      General Purpose

      The Amazon Web Services m8i-flex.12xlarge is a general-purpose instance utilizing the Nitro hypervisor and an x86_64 Intel Xeon 6975P-C processor. It delivers 48 vCPUs clocked at 3.9 GHz, paired with 192.0 GB of DDR5 memory running at 7 GHz. While it lacks local storage and dedicated GPUs, it features advanced instruction sets like AVX-512 and Intel AMX. Benchmarks show strong capabilities, including a Geekbench multi-core score of 19542.0, a Redis SET throughput of 87.32 million operations per second, and 80.84 GB/sec in static web serving. It also performs well in LLM inference, processing 7B model prompts at 260.79 tokens per second. This instance is optimized for general-purpose applications, database operations, software compilation, and web serving.

      Workload Profiles

      3.63Score
      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.
