      Server Description

      An arm64 memory-optimized platform featuring dedicated Graviton cores and high memory bandwidth for demanding database and caching workloads.

      Memory OptimizedGeneral Purpose

      Amazon Web Services r7g.16xlarge is a memory-optimized instance powered by 64-core AWS Graviton ARMv8 Neoverse-V1 processors on an arm64 architecture. Operating at 2.6 GHz with dedicated CPU allocation and no hyperthreading, it features 512.0 GB of RAM, providing 8.0 GB of memory per core. The instance utilizes the Nitro hypervisor and delivers a baseline network bandwidth of 30 Gbps, though it lacks local storage and GPU accelerators. Benchmark data reveals top-tier memory performance and software compilation speeds, alongside strong multi-core CPU capabilities and database operations, including 101.19 million operations per second in Redis SET tests. Conversely, single-core performance and small-model LLM text generation remain average to weak. This profile makes the r7g.16xlarge highly efficient for memory-heavy workloads, such as large-scale in-memory databases, caching layers, and concurrent software compilation, where high memory bandwidth and core density are critical.

      Workload Profiles

      3.3Score
      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.
