Consumers will "see" because the OEMs like Dell and HP are going to go for DX11 cards in their DX11/Win7 machines, rather than tired old Nvidia chips that have been rebadged once too often and that have bitten the OEMs in the ass with Bumpgate. Consumers will "see" the 5xxx reviews showing massive performance increases over current and competitor cards. Consumers will "see" all the DX11/Win7 compatibility stickers and advertisements.
I don't think consumers really know what DX11 means.
And nVidia has Win7 compatibility stickers aswell. You don't need DX11 to get a Win7 sticker.
5xxx with massive performance increases? That remains to be seen.
Even so, as long as the price is right, you don't need to have the fastest card on the market. As long as nVidia gets its price/performance right, they can be a worthy competitor in the budget and mainstream markets (which ironically is the strategy that AMD has been using throughout their 3xxx and 4xxx series, because they just didn't have the performance).
Do you really think consumers are going to say "gee, that Nvidia card is slower and isn't compatible with the latest DX/Win7, but I'll buy it because I get Physx"? No, they'll go for faster, bigger, better, newer, more resolution.
I doubt it. They have no idea what DX11/Win7 means, because there's nothing to show them.
Faster, bigger, better, more resolution... why? Even current cards can run many games at 60+ fps even at HD resolutions, where do you go from there?
PhysX however, well, pretty obvious. "Hey look, on those AMD cards, nothing moves, but on the nVidia cards I see smoke, wind, flying leaves, breaking glass etc".
Yes, I really think consumers are going to prefer that over the vapourware that is DX11.
You can't hold back progress as Nvidia are trying to do.
I don't think nVidia is trying to hold back progress at all. They are working on DX11 hardware, and fully support the DX11 API with their current products, as far as the featureset allows.
In addition, nVidia is offering accelerated physics, while AMD has... nothing.
AMD is holding back accelerated physics as much as nVidia is holding back DX11. Both will eventually support both technologies, but they aren't there just yet.
I think it's likely that nVidia will have DX11 hardware out before AMD has some actual acccelerated physics games running.
People will buy ATI 5xxx because they will be perceived, reviewed, sold and marketed as "newer and better". You can't take an old Nvidia card and call it new and better just because it has Physx capability that has a minor impact on a few titles. Physx is not an inflection point - DX11 and Win7 is.
Correction: PhysX IS an inflection point, accelerated physics are here to stay.
DX11 and Win7 WILL BE inflection points, but they haven't quite reached critical mass yet. PhysX is already well on its way.
By the time DX11 and Win7 become relevant, nVidia will have its hardware ready, so it's a moot point. Physics however... AMD is at Intel's mercy, not a good place to be.
Basically you're saying that consumers are going to prefer a DX11 sticker over obvious PhysX eyecandy in actual games.
No marketing department is THAT good, especially not AMD's
AMD is just good at pissing off developers.
