The Voodoo 2 was a GPU made by 3dfx. The Voodoo2 was released in February 1998 as a replacement for the Voodoo1. The Voodoo2 boosted the core clock-rate from 50MHz to 90MHz, increased the memory bus from 128-bit to 192-bit, and increased texture and framebuffer memory support (up to 8 MB texture / 4 MB frame buffer compared to the Voodoo's 4 MB texture / 2 MB frame buffer.) The larger framebuffer supported a maximum screen resolution of 800x600, while the increased texture-memory allowed more detailed textures.

In a seeming contradiction of Moore's Law, Voodoo2 had an increased chip-count (of 3) compared to the two-chip Voodoo1. Competing products such as the ATI Rage Pro, NVIDIA Riva 128, and Rendition Verite2200 were single-chip products with integrated 2D/VGA cores. The Voodoo2's third chip was a second TMU (texture map unit), which allowed a second texture to be drawn during the same pass, with no performance penalty. At time of introduction, Voodoo 2 was the only 3D-card capable of single-cycle dual-texturing. Of course, usage of the Voodoo2's second TMU depended on application software; Quake II exploited dual-texturing to great effect. The Voodoo2 also inherited the Voodoo 1's usage model: it was a strictly 3D-only card and required the same external pass-through cabling familiar to owners of the Voodoo 1. Growth of transistor counts for Intel processors (dots) and Moores Law (upper line=18 months; lower line=24 months) Moores law is about the empirical observation, that at our rate of technological development, the complexity of an integrated circuit, with respect to minimum component cost, will double in...

Finally, the Voodoo2 introduced Scan-Line Interleave (SLI) capability to the consumer PC market. (The Voodoo1 also had SLI capability, but it was only used in the arcade and professional markets.) In SLI-mode, two Voodoo boards were installed in a PC and ran in parallel, with each unit drawing half the lines of the display. Voodoo2 SLI not only doubled rendering throughput, but also increased the maximum supported screen-resolution to a then-impressive 1024×768.
In 1999, 3DFX released the Voodoo 3, which effectively replaced the Voodoo 2 as the company's top-performing product. The Voodoo 3 was essentially a Voodoo 2 SLI on a single board with the addition of the 2D unit from the failed Banshee.
