Server Description
An accelerator-optimized platform featuring four dedicated GPUs and high-capacity memory for demanding parallel processing and large language model inference.
Google Cloud Platform a2-ultragpu-4g is an accelerator-optimized server featuring four NVIDIA Ampere A100 GPUs with 320 GB of total VRAM, 48 vCPUs on an Intel Xeon x86_64 architecture, 680.0 GB of RAM, and 1608 GB of NVMe SSD storage. While single-core CPU benchmarks place the instance in the bottom 25%, its multi-core and memory bandwidth performance sit in the middle 50%. The server achieves top-tier status in LLM inference prompt processing and text generation for medium and large models. This hardware profile is optimized for GPU-heavy workloads, trading off single-threaded CPU speed for massive parallel processing capabilities. It is designed for deep learning, large language model inference, and complex data science workloads.
