      CPU and System Topology

      Server Description

      A memory-optimized x86 instance featuring 768 GB of DDR4 RAM and a high-frequency 4.5 GHz Intel Xeon processor.

      Memory Optimized

      Amazon Web Services x2iezn.6xlarge is a memory-optimized instance featuring 24 dedicated vCPUs and 768.0 GB of DDR4 RAM, driven by an Intel Xeon 8252C processor at 4.5 GHz. Built on the AWS Nitro hypervisor, it delivers a high memory-to-core ratio of 32.0 GB per core. Benchmark results show strong memory performance, with a PassMark memory score in the top 25% and a cached small-block read bandwidth of 1645.5 GB/sec. Single-threaded gzip compression is also strong at 31.88 GB/sec, while general CPU benchmarks fall in the average range. The instance lacks local storage and GPU accelerators, making it inefficient for large LLM inference, where 70B model prompt processing drops to 4.04 tokens/sec. With a 50 Gbps baseline network bandwidth, this instance is designed for memory-intensive workloads such as large in-memory databases, Redis caching, and enterprise application hosting.

      Workload Profiles

      1.29Score
      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.
