      Server Description

      A memory-optimized virtual instance delivering high-density DDR4 RAM and strong multi-core processing for database and caching workloads.

      Memory Optimized

      Amazon Web Services r6i.24xlarge is a memory-optimized server instance featuring 96 vCPUs and 48 physical cores powered by Intel Xeon 8375C processors running at 3.5 GHz. Built on the x86_64 architecture and managed by the Nitro hypervisor, it delivers 768.0 GB of DDR4 memory but lacks local storage and GPU accelerators. The instance provides a baseline network bandwidth of 38 Gbps. Performance benchmarks show strong multi-core capabilities, with stress-ng, Geekbench multi-core, and PassMark CPU scores in the top 25%, alongside top-tier cryptographic performance in the top 10%. However, single-core execution and large-scale LLM text generation represent performance tradeoffs, scoring in the middle and bottom quartiles respectively. This resource profile is suited for memory-intensive applications, database operations, Redis caching, and multi-threaded data processing tasks.

      Workload Profiles

      3.95Score
      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.
