At present’s PC avid gamers can contemplate themselves fortunate on the subject of selecting a graphics card (comparatively, in fact). Whereas there are solely three GPU producers, each mannequin they make is just about assured to run any recreation you want, albeit at various speeds. Thirty years in the past, it was a really completely different image, with over ten GPU firms, every providing its personal approach of rendering graphics. Many have been extremely profitable, others quite much less so.
However none have been fairly like 3d gaming business pioneer Rendition — an important first product, adopted by two less-than-average ones, earlier than fading into complete obscurity, and all inside 5 years. Now that is a narrative value telling!
Do you know? (Editor’s notice)
TechSpot started life in 1998 as a private tech weblog referred to as “Pure Rendition” to report information on the Rendition Verite chip, one of many first shopper 3D graphics processing items. Shortly after, the location was renamed to “3D Spotlight” to broaden protection to the nascent 3D business represented on the time by the likes of 3dfx and later Nvidia and ATI.
In 2001, the location was relaunched pointing to the brand new area TechSpot.com. The title was acquired after the 90s dot-com bubble for a good-looking $200 as the unique house owners had no good use for it. From there, the location expanded to cowl to the whole tech business. By that time, TechSpot was receiving round 1,000,000 guests every month. Nowadays, TechSpot is dwelling to over 8 million month-to-month readers, catering to PC energy customers, avid gamers and IT professionals across the globe.
Unrelated to Rendition’s historical past, however value stating… proceed studying about Rendition under.
A messy begin to the last decade
PC gaming within the early 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 have been notoriously choosy about all of it. However because the years rolled on, PCs grew to become more and more in style purchases, and hundreds of thousands of individuals across the globe proudly owned machines from Compaq, Dell, Gateway, and Packard Bell.
Not that these have been geared toward gaming — $3,000 would get you a pleasant Intel 486DX2 machine, operating at 66 MHz, and boasting 4MB of RAM and a 240 MB laborious drive. However the graphics card? In case you have been fortunate, it might 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, then you definitely’d be cursed with one thing extremely low cost from SiS or Trident.

In comparison with the visible output of the likes of Sega’s Mega Drive/Genesis or the Tremendous Nintendo Leisure System, the graphics from even one of the best PCs have been primary however serviceable. Nevertheless, there have been no video games on that platform that basically pushed the boundaries of the {hardware}.
The very best-selling PC titles all through the youth of the 90s have been point-and-click journey video games, comparable to Myst, or different interactive titles. None of those video games wanted ultra-powerful graphics playing cards to run, simply people who supported 8 or 16-bit colours.
Change was afoot, although. The path that video games have been heading towards was apparent, as 3D graphics have been changing into the norm in arcade machines, although they used specialized hardware to attain this. PC video games that did have 3D graphics, comparable to Doom, have been doing all of the rendering through the CPU — the system’s graphics card merely turned the body into one thing that may very well be displayed on a monitor.
Doom did not want a 3D graphics accelerator
To emulate the graphics seen in Namco’s Ridge Racer, for instance, the house PC would wish {hardware} with comparable capabilities however at a fraction of the retail value. Curiosity from the previous group of graphics firms (ATI, Matrix, S3, and so forth.) was sluggish in forming, so there was loads of scope for recent blood to enter the sphere.
Quite a few startups have been based to design and make new graphics adapters that may be used as a substitute of the CPU for 3D rendering. Enter stage left, Rendition Inc, co-founded by Jay Eisenlohr and Mike Boich, in 1993.
Their ambitions have been easy but massive — create a chipset for an add-in card that supplied acceleration for all 2D and 3D graphical duties, after which promote to gaming {and professional} industries. Nevertheless, they weren’t alone on this endeavor and confronted stiff competitors from 4 different new firms, in addition to people who had been round for a few years already.
First blood is drawn
In 1995, Rendition introduced its first product, the Vérité V1000-E, however because it was a fabless company, it relied on promoting licenses to fabricate and use the design. 4 OEM distributors took up the gauntlet and one 12 months later, Canopus, Inventive Labs, Intergraph, and Sierra all launched playing cards utilizing the brand new chipset.
At present, there’s comparatively little distinction between the varied architectures to be present in graphics playing cards, however the first iterations of 3D accelerators have been remarkably disparate. Rendition took an uncommon strategy with the V1000, because the central chip was primarily a RISC CPU, much like MIPS, performing as a entrance finish to the pixel pipeline.
Working at 25 MHz, the chip might do a single INT32 multiplication in a single clock cycle, however normal rendering tips comparable to texture filtering or depth testing all took a number of cycles to hold out.
Theoretically, the V1000 might output 25 Mpixels per second (generally known as the fill charge of a graphics card), however solely in very particular circumstances. For traditional 3D video games, the chip took not less than two clock cycles to output a single, textured pixel, halving the fill charge.
However Rendition had a couple of aces up its sleeve with its first Vérité mannequin. It did all the triangle setup routines in {hardware}, whereas each different graphics card required this to be finished by the CPU. Because the PC’s central processor was wanted for all the vertex processing in a 3D recreation, this additional function that the V1000 sported gave the CPU a little bit extra respiratory area.

All V1000 playing cards used the PCI bus to hook up with the host pc, one thing that was nonetheless new within the business, and so they might reap the benefits of options comparable to bus mastering and direct reminiscence entry (DMA) for additional 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, which might convert directions from numerous APIs into code for the chipset. In idea, this meant that the Vérité graphics card had the widest software program assist of any in shops at the moment.
Bringing within the massive weapons
The pièce de résistance got here within the type of a quite well-known recreation — Quake.
After the rampant successes of Doom and its sequel, id Software program started work on a brand new title, one that may happen in a completely 3D world (quite than pseudo-3D nature of Doom). Quake was launched in June 1996 and 6 months later, id Software program provided a port of the code, calling it VQuake.
The place the unique recreation did all 3D rendering on the CPU, programmers John Carmack and Michael Abrash rewrote massive elements of the code to reap the benefits of the Vérité’s capabilities. Processors at the moment, comparable to Intel’s Pentium 166, might run Quake at round 30 fps, with a decision of 320 x 200. The mixture of VQuake and Rendition’s graphics card elevated this to over 40 fps, however this additionally included correct bilinear filtering of textures and even anti-aliasing (through a system developed by Rendition and patented a couple of years later).
Which may not sound like a lot of an enchancment, however for the fast-paced nature of the sport, each additional fps and graphical enhancement was welcome. The query to ask, although, is why wasn’t the efficiency higher than this? A part of the reply lies within the V1000’s lack of {hardware} assist for z-buffers, so programmers nonetheless needed to depend on utilizing the CPU to do any depth calculations, and even then do them as little as attainable.
For a primary try at a graphics accelerator, the Rendition Vérité V1000 was fairly good. It was the one providing available on the market that did 2D and 3D, and had plenty of efficiency obtainable, so long as the sport averted its weaknesses — comparable to utilizing DirectDraw or one in every of its proprietary 3D HALs, it was very quick.
The V1000 was additionally notoriously buggy (particularly in motherboards that did not assist DMA), very sluggish when working in legacy VGA modes, and OpenGL assist was very poor. And it will be the latter by which the product would finally be most judged in opposition to.
Taking second place to the star efficiency
One other startup firm that had ambitions on this planet of 3D was 3Dfx Interactive, which fashioned a 12 months after Rendition however launched its first product, the Voodoo Graphics, properly earlier than the V1000. Initially bought to the skilled business, the 3D-only accelerator made its approach into dwelling PCs by 1996/1997, because of the important drop within the value of DRAM.
Boasting a 50 MHz clock pace, this graphics chipset (codenamed SST1) might output a single pixel, with a bilinear filtered texture utilized, as soon as per clock cycle — significantly sooner than anything on the overall market.
Like Rendition, 3Dfx developed its personal software program, referred to as Glide, to program the accelerator however by the point it was being sported in a wealth of OEM fashions (from the identical ones that used the Vérité V1000), one other HAL was launched — MiniGL. In essence, this was a extremely cut-down model of OpenGL (an API usually used within the skilled market) and it took place solely due to one other model of Quake that id Software program launched in early 1997.
GLQuake was created as a result of Carmack did not get pleasure from having to work with proprietary software program — this model utilized a standardized, open-source API to handle the rendering and supplied a much-needed increase to efficiency and the standard of the graphics, with playing cards that supported it. 3Dfx’s MiniGL driver transformed OpenGL directions into Glide ones, permitting its Voodoo Graphics chipset to totally assist GLQuake.

With a 50 MHz clock pace and {hardware} assist for z-buffers, playing cards utilizing the Voodoo Graphics have been notably sooner than any utilizing Rendition’s V1000. 3Dfx’s first mannequin might solely run at a most decision of 640 x 480 and at all times in 16-bit shade, however even one of the best of Vérité playing cards have been half the pace of any Voodoo mannequin.
Makes an attempt have been made to battle again with the discharge of an up to date model (generally known as the V1000L or L-P), that ran on a decrease voltage, permitting it to be clocked to 30 MHz (in addition to assist sooner RAM), nevertheless it was nonetheless so much slower than the 3Dfx’s providing. And the semiconductor business within the Nineties was quite like sports activities generally — historical past tends to overlook those that got here second.
A faltering second act
Rendition started work on a successor to the V1000 nearly instantly, with targets to broaden on the primary mannequin’s strengths, whereas resolving as lots of its failings as attainable. With a launch goal of summer time 1997, the engineers reworked the chip designs — bettering the clock pace and have set of the RISC processor (as much as 3 directions per cycle), increasing the capabilities of the pixel engine ({hardware} assist for z-buffers and single cycle texture filtering, for instance), and altering the reminiscence from the previous, sluggish EDO DRAM to sooner SGRAM.
Chip binning was beginning to turn out to be extra noticeable within the graphics chip business
Chip binning was beginning to turn out to be extra noticeable within the graphics chip business, enabling producers to promote completely different variations of the identical chip, throughout wider value ranges. Rendition took benefit of this by releasing two variations, in September 1997 — the V2100, clocked round 45 MHz, and the V2200, which ran 10 to fifteen MHz sooner. Aside from the clock charges, there was no distinction between the 2 chips, however most distributors simply went with the sooner chip.
The rationale behind this was easy — they might cost much more for it. For instance, Diamond Multimedia initially bought the V2100-powered Stealth II S220 at $99 (finally decreasing it to half the worth when it bought badly), whereas the Hercules Thriller 3D, utilizing a 63 MHz V2200, value $129 for the 4 MB model and $240 for the 8 MB one.
As follow-ups to the V1000, the brand new chips have been a transparent, if considerably understated, enchancment. Efficiency was definitely better and the additional function assist meant higher compatibility with the flurry of 3D video games showing available on the market. Nevertheless, all was not properly at Rendition.
The event of the V2000 collection had apparently been marred by quite a few glitches, partly because of how the corporate designed its chips. Because it had no fabrication vegetation of its personal, many of the testing of the processors was finished through software program. However what works properly in simulations typically would not switch correctly as soon as fleshed out in silicon, and Rendition missed their goal launch by quite a lot of months.
The competitors wasn’t essentially fairing any higher (for instance, 3Dfx’s second providing, the Voodoo Rush, was actually slower than the unique Voodoo Graphics), however the V2000 collection simply wasn’t a large enough step ahead when in comparison with what ATI, Nvidia, and PowerVR have been releasing.

Whereas mip-mapping was lastly launched within the new {hardware}, it might solely be utilized per triangle, whereas all the things else was in a position to do it per pixel. Rendition was additionally nonetheless pushing the usage of its personal software program, maybe at the price of offering higher assist for OpenGL and Direct3D (though each APIs have been now correctly coated).
However there was sufficient curiosity in what the engineers have been doing to garner curiosity and additional funding from different firms.
Hopes and failed ambitions
In 1998, whereas Rendition was nonetheless creating its third iteration of the Vérité graphics chipset, the corporate (IP and employees) was bought to Micron Technology, an American DRAM manufacturing agency that was buying quite a few companies at the moment. The V3000 collection was anticipated to be extra of the identical, albeit with even larger clocks (IBM was scheduled to provide the chip) and a considerably higher pixel engine.
Nevertheless, regardless of getting access to its personal fabs and significantly extra sources, the undertaking did not progress anyplace close to quick sufficient to be a viable product in opposition to these being launched by 3Dfx, ATI, and Nvidia. Micron’s bosses pulled the plug and the V3000 was deserted.
As a substitute, a new direction for the graphics chip was initiated and the V4000 undertaking, scheduled for launch in 2000, was designed to incorporate a bunch of recent options, multi functional chip. Probably the most spectacular of which was to be not less than 4 MB of embedded DRAM (eDRAM). The graphics chip in Sony’s PlayStation 2 (launched March 2000) additionally boasted this side, so it wasn’t an excessively formidable resolution, however Micron wasn’t actually concentrating on consoles or discrete graphics playing cards.
To the administration, the motherboard chipset market gave the impression to be extra worthwhile, as 3D accelerators have been solely of curiosity to PC avid gamers. By making a single processor that might take over the position of the normal (and separate) Northbridge and Southbridge chips, Micron was assured that they’d the cash and other people to beat the likes of Intel, S3, and VIA on the similar recreation.
Finally, it was to not be. The undertaking was dropped over concerns that the one chip would have been far too massive — over 125 million transistors. As compared, AMD’s Athlon 1200 CPU, from the identical interval, comprised simply 37 million transistors. Micron would go on to attempt to develop a chipset for the Athlon processor, which nonetheless had some eDRAM performing as a L3 cache, nevertheless it did not get very far, and the corporate quickly dropped out of 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, however used the title for a budget range of its Essential reminiscence lineup for a couple of years, earlier than swapping it for one thing new.
Playing cards with Vérité chips have been solely on cabinets for a handful of years, although for a short second in the event you needed one of the best efficiency and graphics in Quake, it was the title to have inside your PC. Time pruned away nearly all the different graphics corporations and the market is now dominated by Nvidia, who bought 3Dfx over 20 years in the past. ATI was purchased by AMD in 2006, Creativeness Applied sciences stopped making PowerVR playing cards a couple of years earlier, and Matrox deserted the gaming sector to serve a distinct segment skilled market.
At present, Rendition stays as a tiny footnote within the history of the graphics processor — a reminder of the times when 3D graphics was the following massive factor and chip designers all discovered radically alternative ways to do them. It has been lengthy gone, however not less than it isn’t forgotten.
The story of key {hardware} and electronics firms that at one level have been leaders and pioneers within the tech business, however at the moment are defunct. We cowl probably the most outstanding a part of their historical past, improvements, successes and controversies.
