      Server Description

      An ARMv9-powered general-purpose instance delivering top-tier memory bandwidth and multi-core performance for high-throughput, network-heavy workloads.

      General Purpose

      Amazon Web Services m8gb.16xlarge is a general-purpose instance powered by a 64-core AWS Graviton ARMv9 Neoverse-V2 processor running at 2.8 GHz. Built on the Nitro hypervisor, it features 256.0 GB of memory, translating to 4.0 GB per core, and lacks local storage or GPU accelerators. The instance delivers a baseline network bandwidth of 133 Gbps. Benchmark data highlights top-tier memory bandwidth, multi-core processing, and database operations, alongside strong multi-threaded decompression and software compilation. However, single-core performance and small-model LLM text generation represent notable tradeoffs, performing in the average and weak ranges respectively. This hardware profile is highly suited for multi-threaded applications, high-throughput static web serving, Redis deployments, and software compilation workloads.

      Workload Profiles

      4.2Score
      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.
