Architecture
Upon release, GeForce 256 offered industry-leading real-time 3D rendering performance. It was marketed as "the world's first 'GPU', or Graphics Processing Unit," a term Nvidia defined at the time as "a single-chip processor with integrated transform, lighting, triangle setup/clipping, and rendering engines that is capable of processing a minimum of 10 million polygons per second."
The integration of the transform and lighting hardware into the GPU itself set the GeForce 256 apart from older 3D accelerators that used separate chips for the task. This reduction of 3D graphics solution complexity brought the cost of such hardware to a new low and made it accessible to cheap consumer graphics cards instead of being limited to the previous expensive professionally-oriented niche designed for computer-aided design (CAD). NV10's T&L engine also allowed Nvidia to enter the CAD market for the first time, with a product called Quadro. The Quadro line uses the same silicon chips as the GeForce cards, but has different driver support and certifications tailored to the unique requirements of CAD applications.

Famous quotes containing the word architecture:
“Poetry is not only dream and vision; it is the skeleton architecture of our lives. It lays the foundations for a future of change, a bridge across our fears of what has never been before.”
—Audre Lorde (1934–1992)
“And when his hours are numbered, and the world
Is all his own, retiring, as he were not,
Leaves, when the sun appears, astonished Art
To mimic in slow structures, stone by stone,
Built in an age, the mad wind’s night-work,
The frolic architecture of the snow.”
—Ralph Waldo Emerson (1803–1882)
“They can do without architecture who have no olives nor wines in the cellar.”
—Henry David Thoreau (1817–1862)
