Reading over the specs on the Velocity 100 on the 3dfx website, it sounds like the Velocity is a Voodoo3 2000 with just 8MB of RAM. Everything else seems to be complete – a full 128-bit memory bus, single pass multitexturing, AGP 2x support, and even a 300 MHz RAMDAC. Note that Voodoo3 3000/3500 products do feature a 350 MHz RAMDAC, but this only comes into play at the very highest of resolutions and will not affect most users.

It’s interesting to note that RAM is SGRAM instead of the SDRAM used on the rest of the Voodoo3 line. SGRAM is, in fact, faster and more expensive than SDRAM, but was likely chosen to maintain the 128-bit memory bus with just 8MB of memory.
