PyTorch 2.10+TorchAO: Powering AIPC scenarios on Intel® Core™ Ultra Series 3 processors
New processors and PyTorch optimizations let you run Meta Llama 3.1 8B locally with just a few lines of code.
Intel has launched its Core Ultra Series 3 processors, designed specifically to power the next generation of AI PCs. The chips feature a new integrated Arc GPU with up to 120 TOPS (Trillions of Operations Per Second) of AI performance from 96 XMX AI engines and support for up to 96GB of LPDDR5x-9600 memory. This hardware foundation is built to handle larger AI models and contexts locally, moving complex tasks from the cloud to personal devices.
To unlock this hardware, PyTorch 2.10 introduces key optimizations for Intel's XPU (cross-platform processing unit) backend. The release integrates with TorchAO, a library that simplifies advanced quantization techniques like Int4-weight-only quantization. This combination allows developers to run models from popular libraries like Hugging Face Transformers with minimal code changes. A provided example shows how to load and automatically quantize Meta's Llama 3.1 8B Instruct model for efficient inference on the new Intel platform, enabling a seamless transition from development to deployment on AI-capable PCs and edge systems.
- Intel Core Ultra Series 3 processors deliver up to 120 TOPS of AI performance with 96 XMX engines for local model execution.
- PyTorch 2.10 with TorchAO library enables easy Int4 quantization, letting developers run models like Llama 3.1 8B with few code changes.
- The stack supports full Hugging Face ecosystem integration and popular data types (int4, fp8, bfloat16) for a unified developer experience.
