Voodoo5 6000 Intel Revision 1 (Model 1000-1900): This was the first version of the Voodoo5 6000 and was considered an early Alpha part used only for testing and publicity photos. Cards based on this design had a short life expectancy, were often unstable and incompatible with various motherboards, and typically could not run above 143 MHz. This card used a proprietary 3dfx power supply and sported 128 meg of 5.4ns SDRAM.
Voodoo5 6000 HiNT Revision 2 (Model 2000-2900): This version of the Voodoo5 6000 dropped the Intel PCI bridge chip the original used for a HiNT bridge chip. These cards were capable of being powered from the system PSU or an external power supply and some were clocked as high as 183 MHz and used 5ns SDRAM.(183 MHz was the card's original intended launch speed). The VSA chips used still didn't have a long life expectancy and this version of card may have some problems running FSAA.
