      Server Description

      A balanced x86_64 server configuration delivering sixty-four virtual cores and two hundred fifty-six gigabytes of memory for diverse enterprise workloads.

      General PurposeCompute Optimized

      Amazon Web Services m6a.16xlarge is a general-purpose instance featuring 64 vCPUs and 32 physical cores powered by an AMD EPYC 7R13 processor running at 3.6 GHz. Built on the x86_64 architecture and managed by the Nitro hypervisor, it includes 256.0 GB of DDR4 RAM but lacks local storage and GPU hardware. The instance delivers strong multi-core CPU performance, high cached memory bandwidth, and excellent cryptographic execution, supported by a 25 Gbps baseline network. While uncached memory bandwidth and static web serving throughput are average, its balanced 1:4 vCPU-to-RAM ratio offers a cost-efficient profile for resource-dense workloads. It is highly suited for database operations, software compilation, Redis caching, and general-purpose enterprise applications.

      Workload Profiles

      2.3Score
      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.
