Voodoo2

The Voodoo2 (or Voodoo²) was a set of three graphics processing units (GPU) on a single chipset, made by 3dfx. It was released in February 1998 as a replacement for the original Voodoo Graphics chipset. The card ran at a chipset clock rate of 90 MHz and used 100 MHz EDO DRAM, and was available for the PCI interface. The Voodoo2 came in two models, one with 8 MB RAM and one with 12 MB RAM. The 8 MB card had 2 MB of memory per texture mapping unit (TMU) vs. 4 MB on the 12 MB model. The 4 MB framebuffer on both cards supported a maximum screen resolution of 800×600, while the increased texture memory on the 12 MB card allowed more detailed textures. Some boards with 8 MB could be upgraded to 12 MB with an additional daughter board. Each of the three chips present on the card had its own 64-bit RAM interface, giving the card a "total" bus width of 192 bits. The Voodoo2 had an increased chip-count compared to the original two-chip Voodoo card. Competing products such as the ATI Rage Pro, NVIDIA RIVA 128, and Rendition Verite 2x00 were single-chip products, each with integrated 2D GUI/VGA accelerators. As with the original Voodoo, the Voodoo2 was a dedicated 3D accelerator, and had to be used in conjunction with a conventional 2D graphics card. It required the same external pass-through cabling familiar to owners of the Voodoo.
