      Server Description

      A memory-optimized virtual server featuring a high RAM-to-vCPU ratio and dedicated Intel Xeon processing for memory-intensive workloads.

      Memory OptimizedGeneral Purpose

      Amazon Web Services r6in.xlarge is a memory-optimized instance featuring 4 dedicated vCPUs and 32.0 GB of DDR4 RAM, powered by an Intel Xeon 8375C processor at 3.5 GHz. Built on the x86_64 architecture and the Nitro hypervisor, this instance offers an 8.0 GB memory-per-core ratio but lacks local storage and GPU accelerators. Performance benchmarks indicate average single-core capabilities, supported by AVX-512 and cryptographic hardware acceleration, alongside average static web serving throughput of 6.36 GB/sec. However, multi-core processing and uncached memory bandwidth fall into the lower percentiles. With a baseline network bandwidth of 6 Gbps, the r6in.xlarge is qualitatively cost-efficient for memory-intensive applications that do not demand heavy parallel computing, making it a suitable fit for in-memory caching, moderate database operations, and web serving.

      Workload Profiles

      0.35Score
      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.
