      Server Description

      A memory-optimized, single-core Intel Xeon instance featuring DDR5 memory and advanced matrix extensions for efficient, memory-intensive workloads.

      Memory OptimizedGeneral Purpose

      Amazon Web Services r8i.large is a memory-optimized instance featuring 2 vCPUs and 16.0 GB of DDR5 RAM running at 7 GHz. Powered by a single physical core of an Intel Xeon 6975P-C processor clocked at 3.9 GHz, this x86_64 server utilizes the AWS Nitro hypervisor. It features a large 480 MB L3 cache and supports advanced instruction sets like AVX-512 and Intel AMX. Benchmarks indicate strong single-core performance, highlighted by a Geekbench single-core score of 2163.0 and high single-threaded compression speeds, though multi-core and large-block memory bandwidth benchmarks are relatively weak due to the single-core hardware constraint. Lacking local storage and GPUs, and configured with a 1 Gbps baseline network speed, this instance is qualitatively cost-efficient for memory-bound workloads that do not require heavy parallelization, making it suitable for small databases, caching systems, and basic text-processing applications.

      Workload Profiles

      0.31Score
      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.
