    Server Description

    A high-frequency, memory-optimized compute platform featuring dedicated Intel Xeon cores and fast local NVMe SSD storage for demanding enterprise workloads.

    Memory OptimizedCompute OptimizedStorage & Database

    Amazon Web Services z1d.6xlarge is a high-frequency, memory-optimized instance built on the AWS Nitro hypervisor. It features a 12-core Intel Xeon 8151 processor running at 4.0 GHz, delivering 24 vCPUs with dedicated allocation. The hardware configuration includes 192.0 GB of DDR4 memory, a 900 GB NVMe SSD local instance store, and a 12 Gbps baseline network bandwidth. In performance testing, the instance exhibits strong memory capabilities, achieving a top-tier PassMark memory score and a cached read bandwidth of 1457.41 GB/sec. CPU benchmarks show balanced multi-core performance with a stress-ng score of 26,203.53. Lacking GPU hardware, the z1d.6xlarge is optimized for high-frequency single-threaded tasks, relational databases, electronic design automation, and memory-intensive enterprise workloads rather than large-scale machine learning.

    Workload Profiles

    1.26Score
    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.
