      Server Description

      A memory-optimized x86_64 platform featuring ninety-six virtual CPUs and seven hundred sixty-eight gigabytes of RAM for memory-intensive enterprise workloads.

      Memory OptimizedGeneral Purpose

      Amazon Web Services r6a.24xlarge is a memory-optimized instance featuring 96 vCPUs and 48 physical cores powered by an AMD EPYC 7R13 processor running at 3.6 GHz. Built on the Nitro hypervisor, it provides 768.0 GB of DDR4 memory, establishing an 8.0 GB per core ratio, though it lacks local storage and GPU accelerators. In benchmark testing, the instance demonstrates top-tier multi-core CPU performance and encryption capabilities, alongside strong results in database operations and Redis SET benchmarks. Conversely, uncached large-block memory bandwidth and single-core operations remain average. This hardware configuration is suited for memory-intensive workloads such as in-memory databases, large-scale caching layers, and enterprise applications requiring substantial memory capacity without the need for local NVMe storage.

      Workload Profiles

      2.98Score
      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.
