jprod - I both agree, and disagree with you 🙂
What I agree with:
That Rampage was far enough along in development for, at least at first glance not to be worth canceling. I've heard it said that is why 3dfx didn't include the Gigapixel technology into it, because they had already invested so much, and while it would be better, it would also delay the product to redesign it at such a fundamental level.
Multichip could be an interesting proposition for NVIDIA...though they have publicly bashed the > 1 chip solution.
What I disagree with:
I don't think they'll use Rampage directly (perhaps some of its innovations, whatever they are). Your comparison between the AMD/Nexgen situation is a far cry from the current situation. AMD was wicked late in developing their K5, and because of that, the performance wasn't on par (because it couldn't ramp well enough - it was great per clock, but horrid in ramping). AMD needed Nexgen to even continue as a company. They are lucky that they had the cash to do so, or else we'd have no more AMD in its current state.
This is different: Nvidia doesn't need the technology that 3dfx had per se, except perhaps for the technology that Gigapixel had. I mean, sure it helps, both in the fact that it eliminates a competitor and strengthens them technilogically, as well as in the patent deptartment, but its not like Nvidia is "on their last legs" so-to-speak like AMD was with the K6. The K6 allowed AMD to have time to develop the K7 (and the talent to do so with Nexgen engineers, plus Dirk Meyer from API). Without it, they'd be dead.
