    Server Description

    A high-frequency, memory-optimized compute platform featuring dedicated high-clock processors and integrated local NVMe SSD storage for demanding database workloads.

    Amazon Web Services z1d.2xlarge is a memory-optimized, high-frequency instance powered by the AWS Nitro hypervisor. It features 8 vCPUs from a dedicated 4.0 GHz Intel Xeon 8151 processor, paired with 64.0 GB of DDR4 memory and 300 GB of local NVMe SSD storage. Operating on the x86_64 architecture, it supports AVX-512F and AES instructions. Benchmark data indicates solid performance, with a Geekbench single-core score of 1320.0, a Passmark CPU score of 9862.94, and Redis SET operations reaching 8.47 million operations per second. While multi-threaded decompression and larger LLM inference tasks show lower relative efficiency, its high clock speed and 1:8 vCPU-to-RAM ratio make it highly effective for relational databases, electronic design automation, and memory-bound workloads requiring strong single-thread execution.

    Workload Profiles

    0.54Score
    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.
