That's not how anything works. History is littered with flash-in-the-pan companies that were the talk of the town for a handful of years and then faded away - DeLorean Motor Company is another good example.
Comparing 3DFX with DeLorean is just laughable. You're grasping at straws trying to save your lost argument. No, no, 3DFX had huge success for a while and then was mismanaged LATER, this is well known by everyone who really knows what happened back then.
a) 3DFX had huge success initially, for years - not equivaling a "flash in the pan". Especially as the IT sector can not be compared to the car sector, which again, is laughable. 3DFX was a pioneer of the 3D graphics branch, well respected among people who understand a thing about PCs.
b) they decided to buy a factory and produce GPUs themselves, also denying anyone else to produce cards for them (for the Voodoo 4 and 5 line, which makes it obvious how late this was)
c) as the Voodoo 4 and 5 cards weren't huge successes and they overspent on that endeavor as well, they basically lost the company by going bankrupt
Ugh, this old chestnut again.
If you aren't interested in the discussion, then you don't have to partake. But save us your boring attitude, please. Aside from the many mistakes you make while being so sure of yourself.
3dfx weren't magical visionaries decades ahead of everyone else,
Nobody ever said that, are you sleeping or reading this discussion?
the simple reason they developed SLI is that their GPUs were no longer competitive
Sorry but utter nonsense. The fact is that SLI was their philosophy of doing tech back then, as simple as this, and not whatever you just made up here, for the sake of having an argument that you can't win (due to history and facts not agreeing with you, still). SLI scaled so far, that no other company could compete with it, there were arcade machines that used 8 of these chips in SLI, together. Calling this "inferior tech", is just ridiculous, aside from the fact that they used this tech for many years and has nothing to do with going "SOS" on tech.
It was an interesting stopgap at the right time, but ultimately it was another bad decision that killed the company
Not really, but I have already explained what their ultimate failure was.
I will add to it more explanations:
- marketing, Nvidia marketing was strong, same as it is now (and more even, their marketing was very toxic as well), and they convinced everyone that 3DFX cards are inferior because they didn't have a few features that mattered 0 back then. While also touting their "T&L" horn (among other things), which also wasn't very relevant, a handful of games (if that) supported it.
Thus the doomed and company-dooming Voodoo 5, because it turns out that when your graphics card needs 4 GPUs to be competitive with a single GPU from NVIDIA or ATI, it makes that graphics card really freaking expensive for the same level of performance
Too bad that this is utterly wrong as well.
- The Voodoo 5 6000 was never released, so never played any role in anything, you're basically talking up fantasies that never happened
- The Voodoo 5 6000 was proven to be WAY FASTER than any other card, IF it had been released, by reviewers much later that happened to get a few of these cards in working shape and review them.
- If a Voodoo 5 6000 would have been released with way higher performance than the competition, the top dollar it would've cost, would've been worth it. So you're wrong with that assertion as well.
- The Voodoo 5 5500 was fast enough to compete with the competition at the time. 3DFX lost the company due to other reasons already explained in this post.
Ultimately, if 3DFX hadn't invested to buy up a company to produce their own cards, they would've not gone bankrupt. God knows what would've happened later as 3DFX was already leaving the SLI-route for next-gen and inventing single GPU cards again, the successor to the "VSA-100"-chip and architecture.
