as for the r400? Looking at how far ahead the 9700 was when it came, and how far ahead the x1900 looks to be I am not sure that ati would not have implemented a more complex chip if possible at a given time. Rather than "uneccesary" could it have just been flawed? What looked to be a good design on paper turned out to be bad in practice?
Well the common held belief is that the R400 -> R500 -> Xenos the Xbox360 chip. In no way does that mean R400=Xenos, but supposedly it had similar features and that the devlopment path that was the R400 turned into the Xenos, and ATi felt the transistor cost of adding those features in a desktop model that need support for so much more, and needed more flexability, that it didn't make sense, the Xenos could be stripped down, but the R400 may have wound up being the first 300+M transistor part with everything they wou;d've need to cram into it, who knows?
Of course all is speculation... I just think that if ati could implement a given "thing" or "feature" that may be "uneccessary" at the time but relevant in the future history seems to show that they will do it.
Speculation is fun, no hard conclusions, just figuring. 8)
The way I see it, transistor count is king, even ATi mentioned it vis-a-vis the GF6 series. Considering that they would've bee trying to put a 300+M transistor package into the 130nm process that may have made for a gigantic chip. At that time I doubt they thought it'd be possible to sell a $700+ card, remember SLi wasn't even speculated yet by anyone (including me :lol: ), and the Ultra / XTPE price-gouging hadn't happened yet, the SLi'ed 3D1's etc didn't exist, the GTX-512 didn't exist even on paper. So I'm sure to them they thouught, we'd never sell one of those for good margin. I wouldn't be surprised if that's what stopped them more than any actual hardware glitch persay.
like the aforementioned dx8.1 or even the ps 2.0 in the 9x00 that never saw "real" payoffs until year(s) later when games actually used it.
Actually DX8.1 payed off almost immediately if you played Morrowind (first DX8.1 game [OOoooh shiny see-through water! 8) ]).
Just my 2 bits, you have some good thoughts too though and could be right on with it.
Well it's all a snapshot of MY view of the past and speculation about what may have been possible. Really everyone's got their own take, but I don't think ATi did anything to fall out of favour the way nV did with the whole FX-floptimization issue, but even that, heck good next generation and who cares?!?
Stuff like that only sticks to one generation, and I don't think either can be considered 'out of favour' right now, perhaps not in vogue would be a better term? :mrgreen:
