WebGPU is a low-level graphics API that enables web applications to directly leverage users' graphics hardware for high-performance rendering. As the successor to WebGL, it offers improved performance and reduced overhead while supporting more advanced graphical and computational tasks. WebGPU can collect detailed device hardware information, such as GPU capabilities and performance metrics, to generate unique browser fingerprints that help track and identify users across different websites. Fingerprinting scripts track and identify specific users across the web by analyzing variations in rendering performance and GPU task characteristics, which are unique to each device and browser configuration.
