One downside to the Radeon DDR is that boards shipped with their core and memory downclocked from the promised 200MHz and 183MHz, respectively. The DVI output was more often found on OEM cards, however, as the retail variety usually sported VIVO plugs. Backed by a superior T&L implementation and support for several of the upcoming DirectX 8 features, the Radeon DDR alongside the GeForce 2 GTS ushered in the use of DVI outputs by integrating support for the interface into the chip itself. The ATI Radeon DDR eventually launched for retail in August 2000. That said, ATI went a step further with vertex skinning for a more fluid movement of polygons, and keyframe interpolation, where developers designed a starting and finishing mesh for an animation and the Charisma core calculated the intervening meshes. The GTS also followed ATI’s Charisma Engine in allowing for all transform, clipping and lighting calculations to be supported by the GPU. The feature was believed to have made it to the previous NV10 (GeForce 256) chip but it remained disabled due to a hardware fault. The latter included Nvidia’s version of ATI’s Pixel Tapestry Architecture, named Nvidia Shading Rasterizer, allowing for effects such as specular shading, volumetric explosion, refraction, waves, vertex blending, shadow volumes, bump mapping and elevation mapping to be applied on a per-pixel basis via hardware. Prior to the Voodoo 5’s arrival, ATI had announced the Radeon DDR as “the most powerful graphics processor ever designed for desktop PCs.” Previews of the card had already gone public on April 25, and only twenty-four hours later Nvidia countered with the announcement of the GeForce 2 GTS (GigaTexel Shader). A few internet wits later noted that the 3dfx design team which had moved to Nvidia eventually got both their revenge and lived up to their potential, by delivering the underperforming NV30 graphics chip powering the FX 5700 and FX 5800 cards behind schedule. The death knell sounded a month later for 3dfx when Nvidia purchased its IP portfolio for $70 million plus one million shares of common stock. Adding fuel to the fire, news got out that upcoming Pentium 4 motherboards would not support the 3.3V AGP signalling required Voodoo 5 series. On November 14, 3dfx announced they were belatedly ceasing production and sale of their own-branded graphics cards, something that had been rumoured for some time but largely discounted. The card was originally scheduled for spring as a competitor to Nvidia’s TNT2, but ended up going against the company’s iconic GeForce 256 DDR instead, as well as the much better performing GeForce 2 GTS and ATI Radeon DDR. This produced a slightly blurred picture that, when run in frame sequence, smoothed out the motion of the animation.ģdfx’s technology became the forerunner of many image quality enhancements seen today, like soft shadows and reflections, motion blur, as well as depth of field blurring.ģdfx’s swan song, the Voodoo 4 4500, arrived October 19 after several delays – unlike the 42 that were never released. The Voodoo 5 introduced T-buffer technology as an alternative to transformation and lighting, by basically taking a few rendered frames and aggregating them into one image. Where 3dfx was once a byword for raw performance, its strengths around this time laid in its full screen antialiasing image quality.īut where 3dfx was once a byword for raw performance, its strengths around this time laid in its full screen antialiasing image quality. The latter ended up trading blows with the GeForce 256 DDR and won the high-resolution battle. Diamond’s high-end professional graphics division, FireGL, was spun off as SONICblue and later sold to ATI in March 2001 for $10 million.ģDLabs acquired Intergraph’s Intense3D in April, while the final acts of 3dfx played out towards the end of the year, despite 2000 kicking off with the promise of a better future as the long-awaited Vooneared its debut in July. As part of S3’s restructuring, the company merged with Diamond Multimedia in a stock swap valued at $165 million. VIA assumed control of S3 around April-May which itself was just finishing a restructuring process from the acquisition of Number Nine. Meanwhile, S3 and Nvidia settled their outstanding patent suits and signed a seven-year cross-license agreement. Also in February, 3dfx announced a 20% workforce cut, then promptly moved to acquire Gigapixel for $186 million and gained the company’s tile-based rendering IP.
