      Server Description

      A memory-optimized, network-enhanced virtual server featuring high memory density and 75 Gbps bandwidth for demanding enterprise databases and caching.

      Memory OptimizedGeneral Purpose

      Amazon Web Services r6in.12xlarge is a memory-optimized instance featuring 48 vCPUs and 24 physical cores powered by an Intel Xeon 8375C processor running at 3.5 GHz. It is equipped with 384.0 GB of DDR4 memory, providing a high memory-to-vCPU ratio of 8.0 GB per core. The instance lacks local storage and dedicated GPUs, but compensates with a high baseline network bandwidth of 75 Gbps for EBS and network optimization. Benchmark results place its compute performance in the average tier, with a Geekbench multi-core score of 15528.0, while showing stronger capabilities in encryption and image processing. With its high memory density and robust network throughput, the r6in.12xlarge is designed for memory-intensive workloads such as in-memory databases, caching layers, and enterprise applications.

      Workload Profiles

      2.28Score
      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.
