      CPU and System Topology

      Server Description

      A high-frequency, memory-optimized virtual server delivering 512 GB of RAM and dedicated Intel Xeon processing for memory-intensive enterprise workloads.

      Memory OptimizedCompute Optimized

      Amazon Web Services x2iezn.4xlarge is a memory-optimized instance featuring 16 vCPUs and 512.0 GB of DDR4 RAM, delivering an exceptionally high memory-to-core ratio of 32.0 GB per physical core. Powered by a dedicated Intel Xeon 8252C processor running at 4.5 GHz on the Nitro hypervisor, it provides high-frequency compute capabilities alongside its massive memory footprint. The instance lacks local storage and GPU acceleration, relying on a 15 Gbps baseline network bandwidth for external connectivity. Performance benchmarks show strong memory bandwidth and compression speeds, while general compute and database operations perform in the average tier. This configuration is highly suited for memory-intensive workloads, such as large in-memory databases, caching layers, and enterprise applications that require substantial memory capacity without a corresponding increase in compute cores.

      Workload Profiles

      0.99Score
      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.
