      Server Description

      A memory-optimized server featuring a high-frequency Intel Xeon processor and an exceptional memory-to-core ratio for memory-intensive workloads.

      Memory OptimizedCompute Optimized

      The Amazon Web Services x2iezn.2xlarge is a memory-optimized instance featuring an Intel Xeon 8252C processor with 8 dedicated vCPUs, 4 physical cores, and a high clock speed of 4.5 GHz. It is configured with 256.0 GB of DDR4 memory, yielding an exceptional 32.0 GB of RAM per core, but lacks local storage and GPU accelerators. Running on the Nitro hypervisor, it delivers a baseline network bandwidth of 12 Gbps. Benchmark results show average CPU and memory performance, with a strong single-threaded gzip compression speed of 31.88 GB/sec, though multi-threaded decompression and medium-model LLM inference represent performance tradeoffs. This instance is designed for memory-intensive workloads such as in-memory databases, caching layers, and enterprise applications requiring substantial memory capacity relative to compute resources.

      Workload Profiles

      0.58Score
      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.
