      Server Description

      A memory-optimized x86_64 platform featuring high RAM density and dedicated vCPUs for database and multi-threaded caching workloads.

      Memory Optimized

      Amazon Web Services r5.8xlarge is a memory-optimized instance featuring 32 dedicated vCPUs and 16 physical cores powered by an Intel Xeon 8259CL processor running at 3.1 GHz. Built on the Nitro hypervisor, it provides 256.0 GB of DDR4 memory with a baseline network bandwidth of 10 Gbps, though it lacks local storage and GPU hardware. Benchmark data indicates that while single-core performance is weak, multi-core capabilities, memory bandwidth, and Redis SET operations consistently rank in the average tier. This resource profile offers qualitative cost efficiency for memory-dense workloads that do not demand high single-threaded CPU speeds. The instance is suited for database operations, in-memory caching, multi-threaded processing, and software compilation.

      Workload Profiles

      1.26Score
      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.
