Intel just announced optimizations for PyTorch (IPEX) to take advantage of the AI acceleration features of its Arc "Alchemist" GPUs.PyTorch is a popular machine learning library that is often associated with NVIDIA GPUs, but it is actually platform-agnostic. It can be run on a variety of hardware, including CPUs and GPUs. However, performance may not be optimal without specific optimizations. Intel offers such optimizations through the Intel Extension for PyTorch (IPEX), which extends PyTorch with optimizations specifically designed for Intel's compute hardware.

Intel released a blog post detailing how to run Meta AI's Llama 2 large language model on its Arc "Alchemist" A770 graphics card. The model requires 14 GB of GPU RAM, so a 16 GB version of the A770 is recommended. This development could be seen as a direct response to NVIDIA's Chat with RTX tool, which allows GeForce users with >8 GB RTX 30-series "Ampere" and RTX 40-series "Ada" GPUs to run PyTorch-LLM models on their graphics cards. NVIDIA achieves lower VRAM usage by distributing INT4-quantized versions of the models, while Intel uses a higher-precision FP16 version. In theory, this should not have a significant impact on the results. This blog post by Intel provides instructions on how to set up Llama 2 inference with PyTorch (IPEX) on the A770.
