      CPU and System Topology

      Server Description

      A memory-intensive x86_64 server featuring 512 GB of DDR5 RAM and advanced Intel Xeon processing for memory-dense enterprise workloads.

      Memory OptimizedCompute Optimized

      The Amazon Web Services x8i.8xlarge is a memory-intensive server utilizing the Nitro hypervisor and an Intel Xeon 6975P-C processor. It provides 32 vCPUs (16 physical cores) running at 3.9 GHz, paired with 512.0 GB of DDR5 memory at 7 GHz. The instance does not include local storage or GPUs, but features a 15 Gbps baseline network bandwidth. Performance benchmarks show top-tier results in text processing and strong capabilities in single-threaded compression and image processing. However, text generation for large 70B LLM models is weak, averaging 2.61 tokens/sec. With advanced instruction support like Intel AMX and AVX-512, this instance is qualitatively cost-efficient for memory-dense workloads, including in-memory databases, text processing pipelines, and medium-scale language model prompt processing.

      Workload Profiles

      2.7Score
      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.
