The Canopus Pure3D is unique in that it's a 6 MB card but also has a TV Out, enabling you to run your 3D games from a TV in addition to your monitor!Ĭompetition for the 3dfx Voodoo 1 card arrived a whole year later in 1997 with nVidia's launch of the Riva 128. The first graphics card manufacturer to use the Voodoo 1 chipset was Diamond, with the launch of the Monster 3D - a 4 MB card. The Voodoo's lowest supported resolution is 512 x 384. The 2 MB frame buffer was good enough for triple-buffered 640 x 480 x 16-bit colour depth, and with proprietary compression (3:1 reduction in size), this 2 MB allowed for many more textures to be stored and reduced bandwidth limitations that would otherwise have been an issue.Ī pass-through VGA cable was daisy-chained the 2D graphics card to the Voodoo, and the Voodoo is then connected to the monitor.Ĭolour writes and Z-buffer are limited to 16-bit, but sensitive alpha blending is performed at 24-bit precision. The design goal behind the original Voodoo was to provide smooth gameplay at a resolution of 640 x 480 with bilinear-filtered textures. Cards with 6 MB still only run games at 640 x 480 but if they have lots of large textures they will run much smoother. 2 MB of this was used as a frame buffer, and 2 MB for texture storage (4 MB on 6 MB cards). (128-bit, 400 MB/s bandwidth, 50 Mpixel/s)ģDfx' first 3D accelerator card, the Voodoo Graphics, comprised a DAC (digital-to-analogue converter), a frame buffer processor (FBI), a texture mapping unit (TMU), and 4 MB EDO RAM. Memory: 4 MB or 6 MB EDO RAM (2 x 64-bit) What did these companies do? They all went to 3Dfx's main competitor at the time, nVidia, to build cards for them instead!ģDfx finally lost market share as Microsoft made DirectX more robust and developers began to move away from OpenGL and 3Dfx' own GLiDE to that.Ĭlick here for a list of games that support 3Dfx cards. With the merger, they would now be creating their own cards, leaving their previous partnerships out in the cold. Prior to this acquisition/merger, 3Dfx had been working with most of the other graphics card manufacturers including Guillemot and Diamond Multimedia. However, in 1998 they purchased STB Microsystems which put a lot of financial pressure on a company that was already struggling in the market. They had thus far relied upon selling their chipsets to other vendors. All these cards offered inferior 3D acceleration to a 3Dfx card but their low cost and the fact they were both 2D and 3D cards combined often appealed to OEM system builders.

Once 3D graphics rendering was becoming more mainstream in PC games, 3Dfx saw further competition from Matrox with their Mystique, S3 with the ViRGE, and ATI's 3D Rage. It became standard for 3D games to offer support for the company's "Glide" API.ģDfx' main competition was from Rendition and PowerVR, who also produced 3D-only accelerator chips. Despite this limitation, the Voodoo Graphics product and its follow-up, Voodoo2, were popular.

The hardware accelerated only 3D rendering, relying on the PC's current video card for 2D work. Their main product was the Voodoo Graphics - an add-in card that accelerated 3D graphics.

Towards the end of 1996 the cost of EDO RAM dropped significantly, enabling 3Dfx to enter the consumer PC market with a full product. Initially they manufactured only the 3D accelator chips which they sold to graphics card companies. 3Dfx was a graphics card manufacturer for the IBM PC and its compatibles from 1994 until 2002.
