      Server Description

      A memory-optimized x86 server featuring ninety-six vCPUs and DDR5 RAM for demanding database and in-memory workloads.

      Memory OptimizedGeneral Purpose

      Amazon Web Services r7i.24xlarge is a memory-optimized server instance utilizing the Nitro hypervisor and an x86_64 Intel Xeon 8488C processor. It features 96 vCPUs across 48 physical cores, 768.0 GB of DDR5 memory running at 5 GHz, and a 38 Gbps baseline network bandwidth. The instance lacks local storage and GPUs. Performance benchmarks show top-tier results in Passmark CPU and encryption tests, alongside strong multi-core stress-ng and memory bandwidth metrics, while single-core performance remains average. Supported hardware extensions include AVX-512 and AMX, which accelerate vector and matrix operations. This resource profile offers qualitative cost efficiency for memory-intensive applications by providing high RAM density per core. It is suited for workloads such as large-scale databases, Redis caching, and CPU-based LLM inference.

      Workload Profiles

      4.28Score
      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.
