In 1988, Silicon Graphics made a collection of workstation computer systems that had been primarily based upon two items of know-how: the MIPS CPU and the IRIS graphics system. The latter included each a {hardware} 3D graphics accelerator and the IRIS GL API. IRIS GL would later grow to be OpenGL. These machines all ran IRIX (a by-product of System V), and these bought decently properly within the workstation market for many who wanted severe 3D energy. With IRIS’s graphics {hardware} and API, SGI felt that they might have a product for the PC house. This was the IrisVision card. The primary push was with Micro Channel. They added 15-pin VGA with a passthrough enter connector. Daughter boards supplied framebuffer and z-buffer reminiscence. As soon as the MCA card was made, work started on a 16 bit ISA slot variant of the cardboard for the compatibles market. Whereas the first card was barely totally different from the MCA model, the daughter boards had been the identical. SGI didn’t know precisely how one can promote this card, and IrisVision was spun off as Pellucid.

Gary Tarolli was born in and grew up in rural New York. He excelled in math and in science, and he went to highschool initially for math at Rensselaer Polytechnic Institute (RPI) in Troy. He then went to CalTech for VLSI engineering. He labored on VAX at DEC throughout graduate faculty, however was recruited by Silicon Graphics the place he labored on chip design software program for workstations.

Scott Sellers was born in Dallas Texas and at a younger age moved to Colorado. He fell in love with computer systems utilizing BASIC on a TRS-80. He attended Princeton for electrical engineering, VLSI engineering, and pc science. He went to work at SGI after commencement the place he spent a whole lot of time on reminiscence.

Ross Smith grew up in Texas and acquired his EE in 1983 from College of Texas in Austin. His introduction to computer systems was with CDC Cyber 70 collection timesharing system. He too began out with BASIC, during which he wrote his first program: tic tac toe. His affinity for computer systems grew as did his curiosity in video games. He began his skilled life working for a protection contractor, and labored with AT&T and Solar on numerous tasks. He then went to work for MIPS, and thru them ended up at SGI.

Gordon Campbell grew up in Minnesota, and as there wasn’t a marketplace for know-how there on the time, he felt he wanted to go to Silicon Valley in 1976. He was employed by Intel the place he created their company advertising and marketing division, and ran it for 3 years. He then did their reminiscence advertising and marketing for two years. He left and began Seeq Know-how in 1981. This firm achieved fairly a bit technologically. For instance, their 16K EEPROM reminiscence chip was the primary to say a minimal of 1 million write cycles. It operated at 5 volts and had a ten millisecond write time. The chip was fitted right into a 24-pin ceramic DIP. Slightly curiously, Seeq used an in-house Silicon Oxynitride course of. In 1982, Seeq developed and commenced promoting the world’s first Ethernet chipset (10mbps). Campbell left Seeq and created Chips and Applied sciences (C&T) in 1984 which was an early fabless semiconductor firm. C&T’s first product was a 4 chip EGA chipset introduced in September of 1985. These 4 chips may replicate the perform of 19 chips on the IBM EGA board. At COMDEX of ‘85 many corporations had launched EGA suitable boards utilizing C&T’s chipset. By the early Nineteen Nineties, Campbell had left C&T and have become a enterprise capitalist.

Whereas at SGI, Tarolli, Sellers, and Smith had all had some publicity to SGI’s Actuality Engine, and with video video games (particularly the PlayStation) shifting towards 3D graphics, all three noticed the potential for client 3D acceleration. Importantly, SGI’s resolution had been all in-silicon, however Gary had seen that the geometry could possibly be achieved on the CPU leaving rasterization as much as the 3D accelerator. This created the IRIS GL system, nevertheless it additionally confirmed that issues could possibly be achieved much less expensively than had beforehand been achieved.

By this level, Tarolli, Sellers, and Smith had been all working at Pellucid and promoting the Professional Graphics 1024. This was the IrisVision made for the PC suitable market talked about earlier. The corporate had many concepts and little focus. Finally, they bought to Media Imaginative and prescient in 1993. Media Imaginative and prescient was a rising power in each pc graphics and pc audio. In addition they acquired into software program publishing, and titles had been usually bundled with their {hardware}. The corporate endured litigation for securities fraud for fairly someday, declared chapter in December of 1994, and have become Aureal Semiconductor Inc on the ninth of September in 1995. This firm would additionally go bankrupt and later be acquired by Inventive.

After Campbell acquired his first fund organized, Smith was interviewing for a place at an organization with which Campbell was concerned and the interview went very badly. It went so badly that Campbell requested Smith what he actually wished to do. The response was that Smith wished to do PC graphics accelerators with two different guys. Nicely, why not do this then! A gathering was then setup. Over a good quantity of beer, the 4 males devised what would grow to be 3dfx. Tarolli, Sellers, Smith, and Campbell based 3dfx Interactive on the twenty fourth of August in 1994.

When launching C&T, Campbell had had Japanese buyers. These contacts got here in useful at 3dfx. Tarolli and Sellers had construct a simulator, purely in software program, of their 3D accelerator and had it operating on a Pentium 90. They then took this to Japan and shopped it to these buyers. The primary pitch was to Mitsui. It didn’t take a lot time for them to get loads of buyers on-board. In the meantime, Smith had designed a GPU enlargement card for PCs (initially they’d wished to do a motherboard and Campbell shot that down repeatedly). The important thing for this group was to do issues cheaply and make the visuals look “ok” to promote. Their product didn’t want the perfection and precision that SGI aimed to ship. In reality, they pulled out a lot that they sacrificed 2D altogether, they usually aimed squarely at 3D realizing that their goal client would have already got some form of 2D card.


To make environment friendly use of silicon and reminiscence, 3dfx used two chips. One chip was the buffer, and the opposite was the T-Rex (texture mapping). Like IRIS GL, the geometry was achieved on the CPU however with the 3dfx GLide API. Collectively this chipset featured: perspective-correct texture mapping, bi-linear and superior filtered textures, multi-level buffering, Gouraud shading, z-buffering, alpha compositing/mixing, anti-aliasing, per-pixel fog, smoke and haze results, texture composition and texture morphing.

The most important hurdle for the group was reminiscence bandwidth. There have been six reminiscence interleaves throughout the 2 chips to aim to beat this, and the shortage of 2D meant that their chips weren’t combating for any reminiscence.

By the point their designs had been despatched off to be made into {hardware}, the corporate had grown to about 12 individuals. The 3dfx chips had been despatched to manufacturing on the sixth of November in 1995. The primary chips got here again a couple of days earlier than the Tremendous Bowl, and on the day of the Tremendous Bowl, the group at 3dfx was testing these chips. At first, they thought they’d made some severe errors. Every thing was operating extremely slowly. They debugged for hours. Smith turned off the debugging instruments, and all of the sudden all the pieces was operating flawlessly! Success!

To make their {hardware} a hit, 3dfx approached recreation builders on to evangelize their {hardware} and the GLide API. They really started doing this earlier than they even had any chips readily available by modifying SGI’s Actuality Engine machines and offering them to builders with GLide and demos of a number of recreation genres to begin engaged on their very own video games. Halfway and the opposite arcade corporations adopting 3dfx elevated the model’s status. Doom launched whereas the playing cards had been in growth, and Quake initially launched with software program rendering.

The primary chips had been put to make use of in arcade machines; as talked about they’d adopted 3dfx’s know-how early (earlier than {hardware} was obtainable). So, as soon as the {hardware} was out within the cupboards, many of those video games had been big hits like San Francisco Rush. The worth of reminiscence, nevertheless, had been falling shortly, the PCI bus grew to become widespread which was crucial for lowering latency from the CPU to the GPU, and the 32 bit transition was successfully full. That 3dfx had ignored legacy turned out to be a great factor. The house client marketplace for 3dfx Voodoo playing cards then exploded. The primary Voodoo card was the Orchid Righteous 3D launched on the seventh of October in 1996. It was manufactured on a 500 nm course of with 1 million transistors. The clock was at 50 MHz, and it may obtain 50 MP/s or 50 MT/s. The cardboard featured 4MB of EDO RAM additionally clocked at 50 MHz with a bus width of 128 bits attaining 800 MB/s. By the top of 1997, 3dfx’s Voodoo Gaphics and the GLide API had been the dominant 3D accelerators and 3D graphics API for the buyer market.

Orchid Applied sciences Righteous 3D, the primary Voodoo card

An engineer at 3dfx constructed a GLide API renderer for Quake, and 3dfx approached John Carmack and id Software program with it. When Carmack noticed the end result, the port was made. Quake ran superbly on Voodoo. This turned out to be an enormous enhance to 3dfx. The launch of Unreal with OpenGL/GLide assist served to additional cement the model within the minds of avid gamers all over the place.

In 1997, 3dfx launched the Voodoo Rush. This mixed a third occasion equipped 2D chip with Voodoo Graphics on a single board on the expense of efficiency. The decreased efficiency wasn’t simply with 3D. The boards sometimes had poor 2D efficiency as properly. Past efficiency troubles, there have been compatibility points with many fashionable recreation titles with early driver releases. All of this meant that the Voodoo Rush was lifeless on arrival.

When SEGA was designing the successor to the SEGA Saturn, a state of affairs developed with SEGA of Japan engaged on a design that used the Hitachi SH4 processor with PowerVR graphics, whereas SEGA of America was engaged on a design that used a PowerPC 603e and Voodoo Graphics. The Hitachi system was code named White Belt, and the PowerPC system was code named Black Belt.

3dfx Interactive was registered on NASDAQ with the image TDFX. Their inventory opened for $11.00 ($20.50 in 2023) at IPO on the twenty fifth of June in 1997. 3dfx raised $33 million ($61,511,588.79 in 2023). The corporate additionally revealed each element of the contract with Sega at IPO. SEGA had been maintaining growth quiet, and SEGA of Japan was apparently fairly upset by the discharge. In consequence, SEGA selected to proceed with White Belt, and the Black Belt mission was terminated. In September of 1997, 3dfx filed a lawsuit towards SEGA and NEC for breach of contract alleging that SEGA had began the deal in dangerous religion. The matter was settled out of courtroom.

The Voodoo 2 launched in March of 1998. It bumped the obtainable RAM to 12MB, elevated the clock to 90MHz, and added a second texture chip (TMU). The Voodoo 2 used 0.35 micron course of. The Voodoo 2 additionally sported Scan-Line Interleave (SLI) the place two playing cards could possibly be linked and every would draw half the strains permitting elevated efficiency.

Towards the top of 1998, the Banshee was launched. Right here, 3dfx did a mixed 2D and 3D design correctly. The Banshee design is actually a Voodoo 2 with solely a single TMU. It did have a better clock at 100 MHz, and the RAM ranged from 8 to 16 MB of SD-RAM or SG-RAM (relying upon board maker and SKU). Some producers pushed the clock to 110 or 120 MHz, and Gigabyte launched a Banshee clocked at 130 MHz. The 2D capabilities of this card, nevertheless, had been high notch. All the Home windows GDI features had been applied in {hardware}, and this 128 bit VESA 3.0 compliant 2D core may deal with MS-DOS video games titles with ease. Whereas it wasn’t fairly as quick at 3D as a Voodoo 2, it was matching or exceeding Matrox within the 2D house, and beating most within the 3D house. It’s value noting that the Voodoo Banshee may render at greater resolutions than the Voodoo 2. By February of 1999, 3dfx had bought over a million Voodoo Banshees.

From the Register on the twenty seventh of January in 1999:

3D graphics chief 3Dfx yesterday reported fourth quarter 1998 revenues of $60.7 million, up 273 per cent on the $22.2 million recorded for a similar interval final 12 months. Nonetheless, the rise in income didn’t translate into equally expanded profitability — for This fall 98, 3Dfx made $2.09 million; the This fall 97 determine was a barely-lower $2.07 million. For the total 12 months, the corporate made $21.7 million, properly up on the $1.7 million loss it posted final 12 months. Income for fiscal 98 totalled $202.6 million, up from final 12 months’s $44.1 million.

Inventive 3D Blaster Banshee

At COMDEX in 1998, 3dfx introduced the Voodoo 3. The Voodoo 3 1000 was launched in March of 1999 with greater priced SKUs releasing in April and June of that 12 months. The Voodoo 3 was successfully a Banshee however with the second TMU just like the Voodoo 2, and a clock of both 125 or 143 MHz. The Voodoo 3 was produced with a 0.25 micron course of, and will obtain 125 MP/s and 250 MT/s.

Up up to now, 3dfx had not been within the board enterprise. It had bought chips to OEMs who made boards. This modified with the Voodoo 3. In December of 1998, 3dfx acquired board maker STB for $141 million ($253,199,099.64 in 2023).

From CNN Money on the 14th of December in 1998:

Ballard says the talks with STB had been initially strategic, with 3Dfx hoping to launch an unique product by STB’s infrastructure. Over the previous few weeks, although, the discussions advanced right into a takeover.

As soon as the acquisition is full, STB’s operations will stay primarily based in Richardson, Texas, with the mixed corporations’ headquarters at 3Dfx’s workplace in San Jose.

3dfx hoped to completely management their model. At this level, avid gamers had 3dfx boards and video games shipped with the 3dfx brand to indicate assist for these boards. 3dfx didn’t need to share their model with Diamond or some other producer. Sadly, this meant that 3dfx would now be competing with each its former board-making companions and different chip makers, which at the very least in keeping with Sellers was a serious motive for the decline of 3dfx. On the similar time, ATI and NVIDIA had been on the rise.

3dfx Voodoo 3

Presently, 3dfx had two merchandise focusing on the low finish of the market, the Velocity 100 and Velocity 200. These had been successfully Voodoo 3 2000s with one TMU disabled. This TMU may simply be re-enabled by way of the Home windows Registry:


Then add:


Set the worth to 2.

The Banshee had given 3dfx an inroad into the OEM PC house, however 3dfx did not proceed down that path with the Voodoo 3. Their growth tempo additionally started to sluggish. ATI’s Radeon and NVIDIA’s RIVA TNT2 had been now providing greater efficiency at roughly the identical worth. GLide was now not so essential as Direct3D was in a position to present good APIs for 3D video games. The Voodoo 4 and Voodoo 5 subsequently didn’t do properly available in the market.

3dfx had been engaged on a brand new accelerator referred to as Rampage. Work started in 1998, and this product nonetheless had some methods to go. In an try to hurry up growth, 3dfx acquired GigaPixel for $186 million ($323,145,296.17 in 2023) on the twenty eighth of March in 2000. This wouldn’t come to a lot. Later in 2000, 3dfx’s collectors initiated chapter proceedings towards the corporate. On the fifteenth of December in 2000, NVIDIA introduced that they’d purchase 3dfx Interactive’s property for $70 million ($121,613,821.14 in 2023) and 1 million shares of widespread inventory.

Curiously, 20 years later, the 3dfx Rampage was examined and located missing towards the NVIDIA GeForce 256 which might have been its competitors had the Rampage been launched. There have been different playing cards in growth at 3dfx that might have been somewhat aggressive, however these by no means noticed the sunshine of day.

This story brings up many “what ifs.” What if 3dfx had gotten the SEGA Dreamcast contract? Would each corporations have been higher off? What if 3dfx had continued merely doing chips and never gotten into the board enterprise? Would 3dfx then have introduced its merchandise to market extra shortly? I feel that the key sauce for 3dfx was actually the mixture of reasonably priced {hardware} and the GLide API. With competitors in each {hardware} and API, somebody needed to free and 3dfx made a couple of extra errors than the competitors.

Nonetheless, Voodoo Graphics and GLide had been the customary within the PC graphics house for a time. 3dfx created an business that’s going robust at this time, and that business has affected excess of simply gaming. GPUs now energy a number of features in our computer systems, they usually allow AI work as properly. For myself, I didn’t personal a Voodoo within the 90s. My father was type sufficient to bless me with a Matrox Mystique card, and it performed such video games as I had properly sufficient. I did envy my neighbor who had a Voodoo although: “Ah man! She has a Voodoo 3! That’s sick! You wanna see it run Unreal?” So many video games simply seemed and felt higher. As with different articles, I do now have a couple of Voodoo playing cards, and revisiting previous video games with them is sort of the expertise. Apparently, I’m not the one one who feels that manner. On the twelfth of February in 2023, a Voodoo 5 6000 prototype board sold for $15000 on eBay.

In my thoughts, that is a fully insane amount of cash to spend on any little bit of house computing gear, however I get it.
