Yes and no. Back then fabrication was a real problem and now it's far less of a barrier to enter the market. Disruption happens with alarming regularity. Sony disrupted the console space, Apple disrupted the music industry then the phone industry then jumpstarted the pretty dead tablet industry, Samsung disrupted the TV industry. Nvidia and AMD are just been trundling along with little competition than each other and
AMD's R&D is at a ten year low (which means they are spending less on CPU and GPU than when they were just making CPUs) which may explain why they're trailing in market share for both CPUs (always) and GPUs.
Sure and in each of those the market disruption wasn't caused by them, but them taking advantage of a paradigm shift in the market.
High capacity optical storage of games was at the point of changing the industry. It was already in the process of adoption in PCs. Consoles were already made that had it (like the Philips CD-I 2 years prior to the PSX) but none were marketed or supported well (The CD-I for example had mixed messages being presented to the consumer) and couldn't attract serious game developers. Sony saw the market disruption like other companies and first went to Nintendo which didn't go through, and then took the plunge and did it themselves. With sufficient marketing and cash to lure and/or outright purchase franchises for the fledgling console. But it was also something they were already deeply entrenched in. Consumer electronics and optical storage (CD). Heck, the Turbographix-CD was released in 1988 as a presage to the potential paradigm shift, but they couldn't market it worth beans (much like Windows Tablets in the early 2000's).
Samsung didn't really disrupt the TV industry. Unless you consider ATI (a former 2D powerhouse) upsetting the graphics industry by producing the Radeon 9700 pro. But in either case they were already part of the industry. Samsung having made TVs from the 1960's and ATI having been in the graphics industry since the 1980s. It's just that in the Western countries Samsung was relatively unknown until their cheap budget priced LCDs entered the market. Not nearly the same as coming into the market from nowhere like NVidia.
Apple took advantage of the market disruption that .MP3 represented. Digital Music. They didn't cause the market disruption. Again, a place where everyone was basically reset to 0 or near 0. While the established music player maker's were either ignoring this format or not finding ways to properly market it, it was a perfect opportunity for an upstart to jump in. Cost to manufacture was low. All you had to do was present it in an attractive package with navigation that was easy to use with marketing that was very good. Something Apple had experience in, but could not take proper advantage of when faced with the Wintel behemoth.
Back to the GPU market. There is no market disruption for a upstart to take advantage of. There's a behemoth in the room in Nvidia (like Windows for OS or Intel for CPUs). You can't just make something different (3D accelerated rendering) because nothing is changing there like there was with the transition from 2D -> 3D. Or the transition from CD-players to MP3/Digital music players. Or the transition from CRT -> LCD.
There isn't even a situation where an upstart like Vizio can enter the market and become a major player like it did with LCD TVs. LCD TVs were on the verge of becoming a commodity market when they entered. Panel makers (Samsung, LG, Sharp, etc.) were selling A-/B grade panels for cheap rather than writing them off. There is no similar opportunity here.
And lets not even get into the IP and Patent minefield that exists with mature and well established market entities in a technology dominated market. When Nvidia entered there wasn't much there with regards to consumer level 3D rendering hardware. Now, it would be extremely difficult make a clean design. As an upstart you likely also won't be getting much in the way of cross-licensing. Anything you license would likely also be at a high cost in addition to having to design something that can compete in a very heavily contested market. It isn't like Nvidia are ignoring a particular market segment as Intel was with low power CPUs.
Hypothetically speaking, if Holographic rendering greatly changed how graphics acceleration could be handled, that would provide an upstart a opening to develop its own IP portfolio. Which then gives it leverage in negotiations with established players if they need to license/cross-license in order to implement something. But I don't see that happening.
Also, who is going to pony up the funds to enter into a market where you'll need a large legal budget. A large R&D budget (starting off from scratch, AMD and Nvidia spend relatively less as they are interating on past hardware designs with minor and sometimes not so minor changes). A very large marketing budget (to compete with NVidia's marketing). For a market where it's difficult for even the market leader to make large profits (although that's gotten better now that AMD aren't as competitive as they were in the past).
So I think at least 1 of 2 things needs to happen for a completely new player to enter the arena.
1. The GPU market must become a commodity market or close to a commodity market. And the existing players start reselling their GPUs to other companies for other companies to rebrand them as their own. This isn't likely to happen.
2. The GPU market shifts in such a way that it completely changes how consumer GPUs are designed. Similar to the 2D -> 3D shift. I don't see anything on the horizon with the potential to do this. Ray-traced rendering maybe?
Other than that the best way is going to be to aquire an existing GPU maker and its IP and patent portfolio. And then have enough funding to establish a serious contender. And that's even assuming the GPU maker has IP and patents relevant to the current market and the ability to make competitive products with that IP and patents. Something that couldn't be said with all the failed former 3D accelerated graphics companies (like Rendition or 3DLabs) when they were aquired.
Hence why I only brought up Intel and Imagination in addition to AMD previously.
