      CPU and System Topology

      Server Description

      A memory-optimized x86 server featuring high-speed DDR5 RAM and dedicated Intel Xeon compute for memory-intensive workloads.

      Memory OptimizedGeneral Purpose

      Amazon Web Services x8i.2xlarge is a memory-optimized server instance featuring 8 dedicated vCPUs and 128.0 GB of DDR5 memory running at 7 GHz. Powered by an Intel Xeon 6975P-C processor with a 3.9 GHz clock speed and a 480 MB L3 cache, this instance delivers strong single-core performance, particularly in text processing and single-threaded compression benchmarks. It operates on the AWS Nitro hypervisor and provides a baseline network bandwidth of 4 Gbps, though it lacks local storage and GPU accelerators. The high memory-to-vCPU ratio of 16 GB per core makes it qualitatively cost-efficient for memory-bound applications. It is highly suited for in-memory databases, caching layers, and text processing workloads.

      Workload Profiles

      0.98Score
      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.
