Graphics Processing Unit

Graphics Processing Unit is computing hardware whose architecture, fabrication, performance, power use, and failure modes shape system behavior. Performance is judged through fabrication process, thermal design, and memory hierarchy, distinguishing laboratory demonstrations from reliable use outside controlled settings.

The page treats performance per watt; memory and interconnects; and manufacturing constraints as distinct parts of Graphics Processing Unit. One line of support comes from power measurements, and a separate test comes from independent hardware analysis; together they clarify memory and interconnects, but the evidence is read with the caveat that vendor specifications may not represent sustained performance in real workloads.
