      Server Description

      An ARM64 memory-optimized instance delivering high memory bandwidth and dedicated core performance for database and caching workloads.

      Memory OptimizedStorage & DatabaseGeneral Purpose

      Amazon Web Services r7g.12xlarge is a memory-optimized instance featuring 48 dedicated ARMv8-based AWS Neoverse-V1 cores running at 2.6 GHz on the Nitro hypervisor. It provides 384.0 GB of system memory, translating to 8.0 GB per core, with no local storage or GPU accelerators. The instance delivers top-tier memory performance, with uncached read memory bandwidth reaching 253.07 GB/sec and a strong PassMark memory score. Multi-core benchmarks, such as software compilation and Redis SET operations (77.38 million operations per second), show strong performance, while single-core metrics remain average. With a 22 Gbps baseline network bandwidth, this instance is highly efficient for memory-intensive workloads. It is well-suited for in-memory databases, caching layers, relational databases, and multi-threaded compilation tasks.

      Workload Profiles

      2.81Score
      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.
