    Server Description

    A high-frequency, memory-optimized compute instance featuring dedicated cores, fast local NVMe storage, and balanced database performance.

    Memory OptimizedCompute OptimizedStorage & Database

    Amazon Web Services z1d.3xlarge is an x86_64 memory-optimized instance featuring a high-frequency Intel Xeon 8151 processor. It delivers 12 dedicated vCPUs (6 physical cores) running at 4.0 GHz, paired with 96.0 GB of DDR4 RAM and a 450 GB local NVMe SSD. Operating on the Nitro hypervisor, the instance achieves average-tier benchmark results, including a stress-ng multi-core score of 13093.09 and 12.59 million Redis SET operations per second. While it offers high single-core clock speeds and a 1:8 vCPU-to-RAM ratio, tradeoffs include a baseline network speed of 5 Gbps and weak prompt processing performance on medium 7B LLM models. The z1d.3xlarge is designed for memory-intensive workloads, relational databases, and high-frequency computing tasks that benefit from fast local storage and high clock speeds without requiring GPU acceleration.

    Workload Profiles

    0.74Score
    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.
