      Server Description

      A high-performance general-purpose virtual server featuring sixty-four dedicated AMD EPYC cores and high-speed DDR5 memory for demanding enterprise workloads.

      General PurposeCompute Optimized

      Amazon Web Services m8a.16xlarge is a general-purpose instance featuring 64 dedicated AMD EPYC 9R45 vCPUs running at 4.5 GHz and 256 GB of DDR5 memory. Built on the AWS Nitro hypervisor, this x86_64 server delivers top-tier performance in CPU and memory benchmarks, including stress-ng, PassMark, and Redis operations. It supports advanced instruction sets like AVX-512 and cryptographic acceleration, but lacks local storage and discrete GPUs, relying instead on a 30 Gbps baseline network interface for external storage connectivity. The balanced 4 GB of RAM per core makes it highly efficient for enterprise workloads, database hosting, and medium-scale LLM inference.

      Workload Profiles

      6.6Score
      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.
