    Server Description

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

    Memory OptimizedCompute OptimizedStorage & Database

    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.
