graphical processing unit (GPU)
What It Means
A GPU is a computer chip originally designed to render graphics and video, but it turns out to be exceptionally good at the mathematical calculations needed for AI and machine learning. Unlike regular computer processors that handle tasks one at a time, GPUs can perform thousands of simple calculations simultaneously, making them much faster for training AI models.
Why Chief AI Officers Care
GPUs are often the largest cost component in AI infrastructure, potentially representing 60-80% of your compute budget for machine learning projects. The choice between buying, renting, or using cloud-based GPUs directly impacts project timelines, as training complex models that might take months on regular computers can be completed in days or weeks with proper GPU resources.
Real-World Example
A retail company training a computer vision model to detect damaged products on assembly lines found their project stalled when using regular servers - the model would take 6 months to train. After switching to a cloud GPU cluster, the same training completed in 3 days, allowing them to deploy the quality control system before the holiday shopping season.
Common Confusion
People often think any GPU will work for AI, but consumer gaming GPUs lack the memory and precision needed for large AI models. Additionally, many assume that more GPUs always means faster training, but without proper software optimization, adding GPUs can actually slow things down due to communication overhead.
