      Server Description

      A memory-optimized x86_64 virtual server featuring dedicated AMD EPYC processors and 64 GB of RAM for memory-intensive workloads.

      Memory OptimizedGeneral Purpose

      Amazon Web Services r6a.2xlarge is a memory-optimized instance featuring an AMD EPYC 7R13 processor built on the x86_64 architecture. Running on the Nitro hypervisor, it provides 8 dedicated vCPUs across 4 physical cores at 3.6 GHz, paired with 64.0 GB of DDR4 memory. The instance lacks local storage and GPU accelerators, relying on network-attached storage and offering a baseline network bandwidth of 3 Gbps. Benchmark data highlights strong single-core CPU performance, though uncached large-block memory bandwidth remains a relative bottleneck. This resource profile delivers a cost-effective balance for memory-intensive applications that do not demand high local disk I/O. It is primarily suited for in-memory databases, Redis caching, and memory-heavy enterprise workloads.

      Workload Profiles

      0.476Score
      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.
