Notes:

• ¹ Shared by two processors; effectively 16 MB RAM.
• ² Shared by two processors; effectively 32 MB RAM.
• ³ Shared by four processors; effectively 32 MB RAM.
• ⁴ The Voodoo 5 6000 was originally intended to have a core and memory clock of 183 MHz, but 3dfx reduced the clock speed to 166 MHz in an attempt to get the boards stable while operating in 2/4/8x AA modes. Since the instability problem was due to a design flaw in the PCB the reduction in clockspeed did nothing in regards to the problem. 3400 and 3700 boards with the "PCI bus modification" by ex-3dfx engineer H.S. run stable in all modes with speeds upwards of 190 MHz.
• ⁵ Macintosh versions were released later with the same specs, but only in PCI.
• ⁶ Pixel pipeline/s x Texture management unit/s (TMU).
• ⁷ Fillrate is measured in Megapixels/sec for pixel fillrate and Megatexels/sec for texture fillrate. Taking advantage of double texture fillrate per clock cycle requires the game engine to make use of multitexturing.
• ⁸ Voodoo boards with multiple chips often have independent memory busses for each chip's memory bank. This resulted in boards with large amounts of memory, but the memory was split between the completely separate chips. So while a Voodoo2 has 8 or 12 MB of RAM, this RAM is split up between the texture and framebuffer.

In the case of Voodoo2 12 MiB, there is 4 MB texture RAM for each texture processor and 4 MiB for the framebuffer. When a game is not multitexturing, a total of 8 MiB texture memory is available. With multitexturing, this is halved to 4 MiB. SLI, however, does not double the available RAM because the boards separately calculate their part of the scene.

This split-RAM architecture caused the resolution limits on the older boards. For Voodoo Graphics 4 MB RAM (2 MB framebuffer) framebuffer size only allowed for a 640x480 resolution when z-buffering was used. Some games managed 800x600 without z-buffer, such as MechWarrior 2: 31st Century Combat 3Dfx Edition, Star Wars Jedi Knight: Dark Forces II, and Need for Speed III: Hot Pursuit
