3dfx Voodoo 5 5500 AGP Video Card for Parts
While capacity is not cumulative across the entire card, bandwidth is effectively cumulative and thus a card with 2x VSA processors has similar bandwidth to d3fx single-chip graphics card using bit DDR memory. The VSA chips used still did not have a long life expectancy, and may have had problems running anti-aliasing. Rendering calculations are bits wide in VSA but the operands and results are stored as bit.
Little is known about this 3dfxx except that this is the final revision.

The Voodoo 5 comes in three flavors: The precarious financial situation of 3dfx was another factor contributing to the ‘s demise. The chip has a larger texture cache than its predecessors and the data paths are bits wide rather than bit.
Released after the Voodoo 5the Voodoo4 is the budget implementation of the VSA product. When rendering to the T-buffer, VSA can store the combined outputs of several frames. Vooxoo5 mechanism allows for creation of effects such as motion blur if used temporally and anti-aliasing if used spatially.
Initial models had the chips mounted in the arrangement seen in the photograph, but this required a PCB with eight circuitry layers most GeForce 2 cards were four-layer, while the Voodoo 5 was six-layer and would have been unreasonably expensive. Compared to the single-chip GeForce and Radeon cards, 3dfc Voodoo5 is burdened with much redundancy and a complicated board. Theoretically, anywhere from 1 to 32 VSA GPUs could be run in parallel on a single graphics card, and the fillrate of the card would increase proportionally.
However, the process was tweaked with a 6th metal layer to allow for better density and speed, and the transistors have a slightly shorter gate length and thinner gate oxide.
In some cases, the was shown to compete well with the next-generation GeForce 3. The results showed that the Voodoo 5 outperformed the GeForce 2 Ultra and Radeonwhich were the fastest iterations of the GeForce 2 and Radeon R lines, respectively. The Voodoo 5 is the unreleased high-end product in the Voodoo5 line.
The VSA supports a hardware accumulation buffer, known as the “T-buffer”. Most of the problems seen in earlier revisions were fixed, although there may have been glitches while in anti-aliasing mode on some cards. Retrieved from ” https: Voodoo5 ReviewFiringsquad, The limitation of px x px maximum texture dimensions was also addressed and VSA can use up to px x px textures.
Views Read Edit View history. It was built on a nm semiconductor manufacturing process, as with Voodoo3. This is the first 3dfx graphics chip to support full bit color depth in 3D, compared to bit color depth with all previous designs. This page was last edited on 17 Novemberat It used only one VSA chip and did not need an additional 3ddx connection. It was rumored that GeForce 2 3dvx was intended to prevent 3dfx taking the lead with their Voodoo 5 A major drawback to this method of performance scaling is that various parts of hardware are needlessly duplicated on the cards and board complexity increases with each additional processor.
However, it was early in its development and only approximately twenty working cards were produced before 3dfx went bankrupt, and most assets were purchased by NVIDIA in late Later, unreleased boards were planned to offer a bit DDR memory design instead, in order to reduce board costs through lower complexity, while offering similar RAM performance. 3fdx capacity and bandwidth is separately dedicated to each VSA processor.
It was meant to be the retail unit, but shortly after the run of 10 were produced, the series was cancelled. With regards to performance, little was known until enthusiasts were able to get pre-release hardware and run tests on it.
One of the design goals for the VSA was scalability. These cards generally had a short life expectancy, and were largely incompatible with various motherboards at the time.
