      Server Description

      A high-frequency, memory-optimized virtual server featuring dedicated Intel Xeon cores and DDR5 memory for single-thread intensive workloads.

      Memory OptimizedCompute Optimized

      Amazon Web Services r7iz.xlarge is a memory-optimized virtual server powered by the Nitro hypervisor and an Intel Xeon 6455B processor running at 3.9 GHz. It features 4 dedicated vCPUs, 32.0 GB of DDR5 RAM at 5 GHz, and a 2 Gbps baseline network speed, with no local storage or GPU. The server excels in single-core performance, delivering strong results in single-threaded compression and Geekbench single-core tests. However, it exhibits weaker multi-core scaling and uncached memory read bandwidth. This hardware profile is qualitatively cost-effective for memory-intensive tasks that depend heavily on high single-thread CPU clock speeds rather than massive parallel execution. It is best suited for memory-bound applications, single-threaded data processing, and light database workloads.

      Workload Profiles

      0.518Score
      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.
