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