As we speak’s PC avid gamers can contemplate themselves fortunate with regards to selecting a graphics card (comparatively, in fact). Whereas there are solely three GPU producers, each mannequin they produce is sort of assured to run any sport you want, albeit at various speeds. Thirty-plus years in the past, the panorama was very completely different, with greater than ten GPU corporations, every providing its personal strategy to rendering graphics. Some had been extremely profitable, whereas others had been much less so.
However none had been fairly like Rendition, a pioneer of the 3D gaming business. It had an awesome first product, adopted by two underwhelming ones, earlier than fading into obscurity – all inside 5 years. Now that is a narrative price telling!
A messy begin to the last decade
PC gaming within the early Nineteen Nineties was thrilling and irritating in equal measure – getting {hardware} to work correctly required countless fiddling about with BIOS and driver settings, and even then, video games on the time had been notoriously choosy about all of it. However because the years rolled on, PCs turned more and more fashionable purchases, and hundreds of thousands of individuals across the globe proudly owned machines from Compaq, Dell, Gateway, and Packard Bell.
Not that these had been aimed toward gaming. Spending $3,000 would get you a pleasant Intel 486DX2 machine, working at 66 MHz, and boasting 4MB of RAM and a 240 MB onerous drive. However the graphics card? If you happen to had been fortunate, it may need sported an ATI Graphics Extremely Professional 2D accelerator, replete with 1 MB of VRAM and the Mach 32 graphics chip. But when girl luck wasn’t in your aspect, you then’d be cursed with one thing extremely low cost from SiS or Trident.
8-bit colour was typical for an inexpensive 1991 graphics card.
In comparison with the visible output of consoles like Sega’s Mega Drive/Genesis or the Tremendous NES, even the perfect PC graphics had been fundamental however serviceable. Nonetheless, there have been no video games on that platform pushing the {hardware} to its limits.
The very best-selling PC titles all through the youth of the 90s had been point-and-click journey video games, resembling Myst, or different interactive titles. None of those required highly effective graphics playing cards to run – simply people who supported 8- or 16-bit colour.
Change was on the horizon. The course video games had been heading was clear as 3D graphics had been changing into the norm in arcade machines, although they used specialised {hardware} to attain this. PC video games that featured 3D graphics, like Doom, dealt with all of the rendering by the CPU, with the system’s graphics card merely turning the body into one thing that could possibly be displayed on a monitor.
Doom did not want a 3D graphics accelerator
To emulate the graphics seen in video games like Namco’s Ridge Racer, for instance, a house PC would want {hardware} with related capabilities, however at a fraction of the arcade’s retail worth. Curiosity from the previous group of graphics corporations (ATI, Matrix, S3, and so on.) was gradual to develop, leaving loads of room for contemporary blood to enter the sphere.
Quite a few startups emerged, designing new graphics adapters that might take over 3D rendering from the CPU. Enter stage left, Rendition Inc, co-founded by Jay Eisenlohr and Mike Boich, in 1993.
Their ambitions had been easy but daring – create a chipset for an add-in card would deal with each 2D and 3D graphics acceleration, then promote it to each gaming {and professional} industries. Nonetheless, they weren’t alone on this endeavor and confronted stiff competitors from 4 different new corporations, in addition to people who had been round for a few years already.
Somewhat Easter egg
Do you know this about TechSpot’s historical past?
TechSpot began life in 1998 as a private tech weblog known as “Pure Rendition” created to report information on the Rendition Verite chip, one of many first shopper 3D graphics processing models. Shortly after, the location was renamed to “3D Highlight” to develop its protection to the rising 3D business, represented on the time by corporations like 3dfx, and later Nvidia and ATI.
In 2001, the location relaunched below the brand new area TechSpot.com. The identify was acquired after the 90s dot-com bubble for a good-looking $200, as the unique house owners now not had a use for it. From there, the location expanded to cowl to your complete tech business. By that time, TechSpot was attracting round a million guests every month. As we speak, TechSpot is house to over 8 million month-to-month readers, catering to PC energy customers, avid gamers and IT professionals worldwide.
Unrelated to Rendition’s historical past, however price mentioning… proceed studying about Rendition beneath.
First blood is drawn
In 1995, Rendition introduced its first product, the Vérité V1000-E. As a fabless firm, Rendition relied on promoting licenses for others to fabricate and use its design. 4 OEM distributors took up the gauntlet, and a yr later, Canopus, Inventive Labs, Intergraph, and Sierra all launched playing cards utilizing the brand new chipset.
As we speak, there’s comparatively little distinction between the architectures of varied graphics playing cards, however the early iterations of 3D accelerators had been remarkably disparate. Rendition took an uncommon strategy with the V1000, designing the central chip primarily as a RISC CPU, much like MIPS, which acted as a front-end to the pixel pipeline.
Operating at 25 MHz, the chip might carry out a single INT32 multiplication in a single clock cycle. Nonetheless, normal rendering duties resembling texture filtering and depth testing all took a number of cycles to hold out.
Theoretically, the V1000 might output 25 Mpixels per second (often known as the fill fee of a graphics card), below very particular circumstances. For typical 3D video games, the chip took at the least two clock cycles to output a single textured pixel, successfully halving the fill fee.
However Rendition had a couple of aces up its sleeve with the primary Vérité mannequin. It dealt with all of the triangle setup routines in {hardware}, whereas each different graphics card required the CPU to deal with these duties. For the reason that PC’s central processor was additionally liable for all vertex processing in a 3D sport, this characteristic of the V1000 gave the CPU some much-needed aid.
ISA VLB slots used earlier than PCI turned commonplace.
All V1000 playing cards used the PCI bus to connect with the host pc, which was nonetheless a comparatively new normal within the business. They might reap the benefits of options like bus mastering and direct reminiscence entry (DMA) for further efficiency.
Rendition’s graphics card was additionally totally programmable (technically, it was the primary ever consumer-grade GPGPU), and the engineers developed a number of {hardware} abstraction layers (HALs) for Home windows and DOS. These HALs transformed directions from numerous APIs into code for the chipset. In principle, this made the Vérité graphics card essentially the most broadly supported by software program on the time.
Bringing within the huge weapons
The pièce de résistance got here within the type of a moderately well-known sport – Quake.
After the rampant successes of Doom and its sequel, id Software program started work on a brand new title, one that will happen in a completely 3D world (not like the pseudo-3D nature of Doom). Quake was launched in June 1996, and 6 months later, id Software program supplied a port optimized for the Vérité chipset, known as VQuake.
Within the authentic model of the sport, all 3D rendering was dealt with by the CPU. Nonetheless, programmers John Carmack and Michael Abrash rewrote giant elements of the code to reap the benefits of the Vérité’s capabilities.
At the moment, processors like Intel’s Pentium 166 might run Quake at round 30 fps at a decision of 320 x 200. With VQuake and Rendition’s graphics card, this elevated to over 40 fps, and the sport included correct bilinear texture filtering and even anti-aliasing (through a system developed by Rendition and patented a couple of years later).
Which may not sound like an enormous enchancment, however for a fast-paced sport like Quake, each further body per second and graphical enhancement made a distinction. Nonetheless, the query stays: why wasn’t the efficiency even higher? A part of the reply lies within the V1000’s lack of {hardware} help for z-buffers, so programmers nonetheless needed to depend on the CPU for depth calculations, and even then, do them as little as doable.
For a primary try at a graphics accelerator, the Rendition Vérité V1000 was spectacular. It was the one product in the marketplace that dealt with each 2D and 3D graphics, and had a lot of efficiency obtainable, so long as the sport averted its weaknesses – resembling utilizing DirectDraw or certainly one of its proprietary 3D HALs, it was very quick.
Nonetheless, V1000 was additionally notoriously buggy (particularly in motherboards that did not help DMA), very gradual when working in legacy VGA modes, and OpenGL help was very poor. In the long run, it was this weak spot in OpenGL that finally outlined the product’s legacy.
Taking second place to the star efficiency
One other startup with ambitions on this planet of 3D was 3Dfx Interactive, based a yr after Rendition, however releasing its first product, the Voodoo Graphics, nicely earlier than the V1000. Initially bought to the skilled market, the 3D-only accelerator made its manner into house PCs by 1996/1997, because of a big drop in DRAM costs.
Boasting a 50 MHz clock velocity, this graphics chipset (codenamed SST1) might render a single pixel, with a bilinear filtered texture utilized, as soon as per clock cycle – significantly sooner than the rest on the final market.
Like Rendition, 3Dfx developed its personal software program, known as Glide, to program the accelerator. Nonetheless, by the point it appeared in a big selection of OEM fashions (from the identical corporations that used the Vérité V1000), one other HAL was launched – MiniGL. Basically, MiniGL was a extremely cut-down model of OpenGL (an API sometimes used within the skilled market) and took place solely due to one other model of Quake that id Software program launched in early 1997.
GLQuake was developed as a result of John Carmack did not take pleasure in working with proprietary software program. This model used a standardized, open-source API for rendering, providing a big increase in efficiency and graphical high quality for supported playing cards. 3Dfx’s MiniGL driver transformed OpenGL directions into Glide ones, permitting the Voodoo Graphics chipset to completely help GLQuake.

With a 50 MHz clock velocity and {hardware} help for z-buffers, playing cards utilizing Voodoo Graphics had been notably sooner than any utilizing Rendition’s V1000. 3Dfx’s first mannequin was restricted to a most decision of 640 x 480 and at all times in 16-bit colour, besides, the perfect Vérité playing cards had been solely half as quick as any Voodoo mannequin.
Makes an attempt had been made to battle again with the discharge of an up to date chip (the V1000L or L-P), which ran at a decrease voltage, permitting it to be clocked as much as 30 MHz and paired with sooner RAM. Nonetheless, it nonetheless lagged behind 3Dfx’s providing. Within the aggressive semiconductor business of the Nineteen Nineties, very like in sports activities, historical past tends to neglect those that are available in second.
A faltering second act
Rendition started work on a successor to the V1000 nearly instantly, aiming to construct on the primary mannequin’s strengths whereas addressing its weaknesses. With a goal launch of summer time 1997, the engineers reworked the chip designs – enhancing the clock velocity and have set of the RISC processor (as much as three directions per cycle), increasing the capabilities of the pixel engine (including {hardware} help for z-buffers and single cycle texture filtering, for instance), and upgrading from gradual EDO DRAM to sooner SGRAM.
Chip binning was beginning to grow to be extra noticeable within the graphics chip business
Chip binning, a observe changing into extra widespread within the graphics chip business, allowed producers to promote completely different variations of the identical chip at numerous worth factors. Rendition took benefit of this by releasing two variations in September 1997 – the V2100, clocked at round 45 MHz, and the V2200, which ran 10 to fifteen MHz sooner. Except for clock velocity, there was no distinction between the 2 chips, however most distributors opted for the sooner mannequin.
The explanation was easy – they may cost much more for it. For example, Diamond Multimedia initially bought the V2100-powered Stealth II S220 for $99 (later lowering it to half worth because of poor gross sales), whereas the Hercules Thriller 3D, utilizing a 63 MHz V2200, was priced at $129 for the 4 MB model and $240 for the 8 MB model.
As successors to the V1000, these new chips had been clear, if understated, enhancements. Efficiency was positively higher, and the extra options improved compatibility with the rising variety of 3D video games hitting the market. Nonetheless, not every part was going easily at Rendition.
Improvement of the V2000 collection had been tormented by quite a few glitches, partly as a result of firm’s design course of. Missing its personal fabrication vegetation, most of Rendition’s processor testing was executed through software program. Sadly, what works nicely in simulations usually would not switch correctly as soon as fleshed out in silicon, and Rendition missed their goal launch by a variety of months.
The competitors wasn’t faring a lot better (3Dfx’s second providing, the Voodoo Rush, was truly slower than the unique Voodoo Graphics), however the V2000 collection merely wasn’t a sufficiently big step ahead in comparison with what ATI, Nvidia, and PowerVR had been releasing.
3dfx’s Voodoo Rush used one chip for 2D (left) and two chips for 3D (proper). Picture : vgamuseum
Whereas the brand new {hardware} lastly launched mip-mapping, it might solely apply it per triangle, whereas rivals might accomplish that per pixel. Rendition additionally continued to push its proprietary software program, maybe on the expense of providing higher help for OpenGL and Direct3D, although each APIs had been now correctly supported.
Regardless of these challenges, Rendition’s engineering efforts garnered sufficient curiosity to draw additional funding from different corporations.
Hopes and failed ambitions
In 1998, whereas Rendition was nonetheless growing the third iteration of its Vérité graphics chipset, the corporate – together with its IP and employees – was bought to Micron Expertise, an American DRAM producer that was buying a number of companies on the time. The V3000 collection was anticipated to be extra of the identical, albeit with greater clock speeds (IBM was slated to provide the chip) and a considerably improved pixel engine.
Nonetheless, regardless of gaining access to its personal fabrication services and much more sources, the undertaking did not progress rapidly sufficient to stay aggressive with merchandise from 3Dfx, ATI, and Nvidia. Micron’s bosses determined to tug the plug, and the V3000 was deserted.
As an alternative, a brand new course was charted, and the V4000 undertaking was initiated, with a deliberate launch in 2000. This chipset was designed to include a number of latest options, essentially the most spectacular being at the least 4 MB of embedded DRAM (eDRAM). The graphics chip in Sony’s PlayStation 2 (launched in March 2000) additionally featured eDRAM, so this wasn’t a very formidable aim. Nonetheless, Micron wasn’t concentrating on consoles or discrete graphics playing cards.
The PS2’s fundamental GPU surrounded by 4MB of eDRAM.
To the administration, the motherboard chipset market gave the impression to be extra worthwhile, as 3D accelerators had been solely of curiosity to PC avid gamers. By making a single processor that might take over the position of the standard (and separate) Northbridge and Southbridge chips, Micron was assured that that they had the cash and other people to beat the likes of Intel, S3, and VIA on the identical sport.
Finally, it was to not be. The undertaking was deserted over issues that the one chip would have been far too giant – over 125 million transistors. For comparability, AMD’s Athlon 1200 CPU from the identical interval comprised simply 37 million transistors. Micron later tried to develop a chipset for the Athlon processor, with some eDRAM serving as L3 cache, however this effort did not go far, and the corporate quickly exited the chipset market altogether.
An ignominious finish
As for Rendition and its graphics processors, it was throughout. Micron by no means did something with the IP, although it briefly used the Rendition identify for a price range vary of Essential reminiscence merchandise, earlier than swapping it for one thing new.
Playing cards with Vérité chips had been solely on cabinets for a handful of years, although for a quick second when you wished the perfect efficiency and graphics in Quake, it was the identify to have inside your PC. Time has pruned away practically all the opposite graphics corporations and the market is now dominated by Nvidia, which bought 3Dfx over 20 years in the past. ATI was acquired by AMD in 2006, Creativeness Applied sciences stopped making PowerVR playing cards however their graphics IP is utilized in trendy chips made by Apple and lots of others, whereas Matrox deserted the gaming sector to serve a distinct segment skilled market.
As we speak, Rendition is a small footnote within the historical past of the graphics processor – a reminder of the times when 3D graphics was the subsequent huge factor, and chip designers pursued radically completely different approaches. Although lengthy gone, Rendition it isn’t forgotten.
The story of key {hardware} and electronics corporations that at one level had been leaders and pioneers within the tech business, however are actually defunct. We cowl essentially the most outstanding a part of their historical past, improvements, successes and controversies.
