GPUs

Also written: GPU

Graphics Processing Units (GPUs) are powerful chips for parallel processing, essential for AI training and inference.

In plain terms

GPUs are specialized computer chips that excel at performing many calculations at the same time. Originally designed to create the graphics you see on screens, their parallel processing power makes them ideal for the massive computations needed to train and run AI models.

Think of it like this: a regular computer chip (CPU) is like a skilled chef who can do many tasks one after another very well. A GPU is like an army of cooks, each doing a small part of a big meal simultaneously. This is why GPUs are so important for AI, allowing complex models to be trained much faster than with CPUs alone.

The expert version

Graphics Processing Units (GPUs) are highly parallel processors originally developed for rendering graphics. Their architecture, featuring thousands of smaller cores optimized for throughput, makes them exceptionally well-suited for the matrix multiplications and tensor operations that dominate deep learning workloads. This parallelization allows for significant speedups in both training large neural networks and performing inference compared to traditional CPUs.

While GPUs offer immense computational power, their use involves tradeoffs. They consume significant power and generate heat, requiring specialized cooling infrastructure. Furthermore, the memory bandwidth and capacity of GPUs can become bottlenecks for extremely large models. The development of AI-specific hardware, like OpenAI's Jalapeño chip, aims to address these limitations by offering improved performance per watt and potentially lower costs compared to general-purpose GPUs from vendors like Nvidia.

Why it matters now

GPUs are essential for the massive computational power needed to train and run advanced AI models. Recent news highlights how companies are seeking to improve or even create their own GPU technology to gain an edge in AI development and deployment.
