      Server Description

      An arm64 memory-optimized instance featuring sixty-four dedicated cores and half a terabyte of RAM for high-throughput database and caching workloads.

      Memory OptimizedGeneral Purpose

      Amazon Web Services r7g.16xlarge is a memory-optimized server instance powered by 64 dedicated physical cores of the arm64 AWS Neoverse-V1 processor running at 2.6 GHz. Operating on the AWS Nitro hypervisor, it features 512.0 GB of RAM, providing a high memory-to-core ratio of 8.0 GB per core, with no local storage or GPU accelerators. Benchmark data highlights top-tier memory performance and multi-core execution, with Passmark memory scores and Geekbench software compilation results ranking in the top 10%. The instance also delivers strong performance in Redis SET operations and static web serving, backed by a 30 Gbps baseline network bandwidth. While single-threaded tasks and small-model text generation show average to weak performance, the dedicated core architecture and high memory capacity make this instance highly efficient for memory-intensive databases, in-memory caching, and multi-threaded enterprise applications.

      Workload Profiles

      3.33Score
      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.
