CPU and System Topology
Server Description
An accelerator-optimized platform pairing an NVIDIA A100 GPU with generous system memory for demanding machine learning and inference workloads.
Google Cloud Platform a2-ultragpu-1g is an accelerator-optimized server designed for GPU-intensive workloads. It features an Intel Xeon x86_64 CPU with 12 vCPUs, 170.0 GB of system memory, a 402 GB local NVMe SSD, and a single NVIDIA Ampere A100 GPU with 80 GB of VRAM. Performance benchmarks demonstrate a significant contrast between CPU and GPU capabilities. The server achieves top-tier results in large language model inference, processing 499.41 tokens per second for prompt processing on a 70B model. However, its single-core CPU performance and single-threaded decompression tasks fall into the bottom 25% tier. Multi-core CPU operations and memory bandwidth perform in the middle 50% tier. This hardware profile is highly optimized for deep learning, LLM inference, and parallelized accelerator tasks, whereas general-purpose single-threaded processing represents a primary tradeoff.
