GeForce 256 was marketed as \"the world's first 'GPU', or\u00a0Graphics Processing Unit<\/a>\", 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\".[<\/span>2]<\/span><\/a><\/sup>[<\/span>3]<\/span><\/a><\/sup><\/p>\n

The \"256\" in its name stems from the \"256-bit QuadPipe Rendering Engine\", a term describing the four 64-bit pixel pipelines of the NV10 chip. In single-textured games NV10 could put out 4\u00a0pixels per cycle, while a two-textured scenario would limit this to 2\u00a0multitextured pixels per cycle, as the chip still had only one TMU per pipeline, just as TNT2.[<\/span>4]<\/span><\/a><\/sup>\u00a0In terms of rendering features, GeForce\u00a0256 also added support for\u00a0cube environment mapping<\/a>[<\/span>4]<\/span><\/a><\/sup>\u00a0and\u00a0dot-product (Dot3) bump mapping<\/a>.[<\/span>5]<\/span><\/a><\/sup><\/p>\n

The integration of the transform and lighting hardware into the GPU itself set the GeForce\u00a0256 apart from older 3D accelerators that relied on the CPU to perform these calculations (also known as software transform and lighting). 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\u00a0computer-aided design<\/a>\u00a0(CAD). NV10's T&L engine also allowed Nvidia to enter the CAD market with dedicated cards for the first time, with a product called\u00a0Quadro<\/a>. 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.[<\/span>6]<\/span><\/a><\/sup><\/p>\n

The chip was manufactured by\u00a0TSMC<\/a>\u00a0using its\u00a0220\u00a0nm<\/a>\u00a0CMOS<\/a>\u00a0process<\/a>.[<\/span>7]<\/span><\/a><\/sup><\/p>\n

There was only one GeForce 256 release, as succeeding GeForce products would have varying chip speeds. However there were two memory configurations, with the SDR version released in October 1999 and the DDR version released in mid-December 1999\u00a0\u2013 each with a different type of\u00a0SDRAM<\/a>\u00a0memory. The SDR version uses\u00a0SDR SDRAM<\/a>\u00a0memory from\u00a0Samsung Electronics<\/a>,[<\/span>8]<\/span><\/a><\/sup>[<\/span>9]<\/span><\/a><\/sup>\u00a0while the later DDR version uses\u00a0DDR SDRAM<\/a>\u00a0memory from\u00a0Hyundai Electronics<\/a>\u00a0(now\u00a0SK Hynix<\/a>).[<\/span>10]<\/span><\/a><\/sup>[<\/span>11]<\/span><\/a><\/sup><\/p>\n
