      Server Description

      A high-frequency general-purpose instance delivering exceptional single-core performance and fast DDR5 memory for compute-intensive and network-optimized workloads.

      General PurposeCompute Optimized

      Amazon Web Services m8azn.3xlarge is a general-purpose, network-optimized instance featuring a dedicated 12-core AMD EPYC 9R05 processor running at 5.0 GHz. It is equipped with 48.0 GB of high-speed 6 GHz DDR5 memory, providing a balanced 4.0 GB per core, and operates on the AWS Nitro hypervisor. The instance lacks local storage and GPUs, relying on a 25 Gbps baseline network bandwidth for storage and connectivity. Performance benchmarks show top-tier single-core CPU execution, image processing, and text processing, alongside strong large-block memory bandwidth. Multi-core and database operations perform at average to strong levels. This configuration is highly efficient for workloads requiring high single-threaded performance, such as web serving, data compression, and small-scale language model inference, offering a balanced resource profile without the overhead of local storage.

      Workload Profiles

      2.34Score
      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.
