NV1<\/p>\n

\"\"<\/p>\n

The\u00a0NV1<\/b>\u00a0was\u00a0Nvidia<\/a>'s first\u00a0graphics accelerator<\/a>, introduced in May 1995 and released later that year as a multimedia\u00a0PCI<\/a>\u00a0card.[<\/span>2]<\/span><\/a><\/sup>\u00a0Manufactured by\u00a0SGS-Thomson Microelectronics<\/a>, sometimes under the model name\u00a0STG2000<\/b>, the chip was sold in retail by\u00a0Diamond<\/a>\u00a0as the\u00a0Diamond Edge 3D<\/b>\u00a0card. The NV1 stood out for its use of\u00a0quadratic texture mapping<\/a>, a departure from the triangular\u00a0primitives<\/a>\u00a0favored by competitors. The use of quadratics made it possible to port games from the\u00a0Sega Saturn<\/a>, however, after the NV1 was introduced, Microsoft announced that\u00a0DirectX<\/a>\u00a0would exclusively support triangle primitives.[<\/span>3]<\/span><\/a><\/sup>\u00a0As a result, the NV1 failed to gain traction in the market.[<\/span>4]<\/span><\/a><\/sup><\/p>\n

In addition to its\u00a02D<\/a>\/3D<\/a>\u00a0graphics core and\u00a0Video RAM<\/a>\u00a0or\u00a0FPM DRAM<\/a>\u00a0memory, the NV1 card also integrated the functionality of a 32-channel playback-only\u00a0sound card<\/a>, and had a\u00a0joystick port<\/a>, along with ports for two Sega Saturn controllers. As such, it was marketed as a \"multimedia card\" that was a replacement for both a graphics card and a\u00a0Sound Blaster<\/a>-compatible audio card in\u00a0IBM PC<\/a>\u00a0compatible systems. However, this made it more expensive, and with many computer owners owning a sound card, the all-in-one design further hurt its market appeal.<\/p>\n

The\u00a0NV2<\/b>\u00a0was a follow-up chip developed for Sega's\u00a0Dreamcast<\/a>, but was ultimately abandoned. Nvidia shifted focus with its next product, the\u00a0RIVA 128<\/a>, which adopted triangle primitives and dropped the audio functionality. This alignment with Direct3D and a more streamlined design made the RIVA 128 a success.<\/p>\n

The\u00a0RIVA 128<\/b>, or \"NV3<\/b>\", was a consumer\u00a0graphics processing unit<\/a>\u00a0created in 1997 by\u00a0Nvidia<\/a>. It was the first nVidia product to integrate 3D acceleration in addition to traditional 2D and video acceleration. Its name is an acronym for\u00a0R<\/b>eal-time\u00a0I<\/b>nteractive\u00a0V<\/b>ideo and\u00a0A<\/b>nimation accelerator<\/i>.[<\/span>2]<\/span><\/a><\/sup><\/p>\n

The RIVA 128 followed Nvidia's less successful \"NV1<\/a>\" accelerator and was the first product to gain Nvidia widespread recognition. It was also a major change in Nvidia's technological direction.<\/p>\n

Riva TNT<\/p>\n

\"\"<\/p>\n

The\u00a0RIVA TNT<\/b>, codenamed\u00a0NV4<\/i>, is a\u00a02D<\/a>, video, and\u00a03D<\/a>\u00a0graphics accelerator chip for PCs that was developed by\u00a0Nvidia<\/a>, announced in March 1998 and released at the end of August 1998.[<\/span>1]<\/span><\/a><\/sup>\u00a0It cemented Nvidia's reputation as a worthy rival within the developing consumer 3D\u00a0graphics adapter<\/a>\u00a0industry. It succeeded the\u00a0RIVA 128<\/a>.<\/p>\n

RIVA is an acronym for\u00a0Real-time Interactive Video and Animation accelerator<\/i>.[<\/span>2]<\/span><\/a><\/sup>\u00a0The \"TNT\" suffix refers to the chip's ability to work on two\u00a0texels<\/a>\u00a0at once (Twin Texel<\/i>).[<\/span>3]<\/span><\/a><\/sup><\/p>\n

The first graphics card that was based on the RIVA TNT chip was the Velocity 4400, released by\u00a0STB Systems<\/a>\u00a0on August 31, 1998.<\/p>\n

Riva TNT2<\/p>\n

The\u00a0RIVA TNT2<\/b>\u00a0is a\u00a0graphics processing unit<\/a>\u00a0manufactured by\u00a0Nvidia<\/a>\u00a0starting in early 1999. The chip is codenamed \"NV5\" because it is the 5th graphics chip design by Nvidia, succeeding the\u00a0RIVA TNT<\/a>\u00a0(NV4). RIVA is an acronym for\u00a0R<\/b>eal-time\u00a0I<\/b>nteractive\u00a0V<\/b>ideo and\u00a0A<\/b>nimation accelerator<\/i>.[<\/span>1]<\/span><\/a><\/sup>\u00a0The \"TNT\" suffix refers to the chip's ability to work on two\u00a0texels<\/a>\u00a0at once (T<\/b>wiN<\/b>\u00a0T<\/b>exel<\/i>).[<\/span>2]<\/span><\/a><\/sup>\u00a0Nvidia removed RIVA from the name later[when?<\/span><\/a><\/i>]<\/sup>\u00a0in the chip's lifetime.[<\/span>2]<\/span><\/a><\/sup><\/p>\n
