      Server Description

      A memory-optimized server combining high-frequency Intel Xeon processing with DDR5 memory for single-thread intensive and memory-bound workloads.

      Memory OptimizedCompute Optimized

      Amazon Web Services r7iz.2xlarge is a memory-optimized instance featuring 8 vCPUs and 64.0 GB of DDR5 memory running at 5 GHz. Powered by a dedicated Intel Xeon 6455B processor operating at 3.9 GHz, this x86_64 architecture server utilizes the Nitro hypervisor. It lacks local storage and GPU accelerators, relying on a baseline network bandwidth of 3 Gbps. Performance benchmarks highlight top-tier single-core and text processing capabilities, alongside strong single-threaded compression speeds. Multi-core performance, database operations, and memory bandwidth fall within average ranges. Qualitatively, the instance offers a high-frequency CPU paired with dense memory, though the lack of local storage and moderate network bandwidth present trade-offs for storage-heavy workloads. It is suited for database management, memory-bound applications, software compilation, and text processing.

      Workload Profiles

      0.847Score
      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.
