what has been is no matter, what is to be is.
amd will with the console deal gain have a great advantage.
they will catch up and surpass nvidia with the frame sync with multi gpu as they already done so with single cards.
Once that happens, Nvidia will go away as 3dfx.
Its extremely unlikely Nvidia will go the same way as 3dfx.
In fact, while AMD's revenue income is about the same as Nvidia, AMD are physically twice the size of Nvidia with much greater overheads and debts.
The good news now for AMD is they have paid down the majority of debts to bring them all down to a manageable level, they have also shrunk their physical size and overheads, with more of all that to come. As of the last quarter AMD were still not profitable, but they did better the predictions of their fanatical situation at that point, and still have a lot of cash and assets, more than enough to continue on through 2014 at current levels of looses.
The difference in revenue structures is, GPU sales make up a far higher percentage of revenue for Nvidia than GPU sales do for AMD.
AMD's revenue is made up of
A, Both retail and commercial CPU's
B, GPU's
C, AMD own the SeaMicro server company
D, a portfolio of Intellectual Property, such as the 64Bit part of all CPU's, including Intel who licence that from AMD, Motherboard Chip-Sets, The GPU in the xBox 360 and Nintendo Consoles, some of the technology you find in medical equipment, car Dashboard computers, TV's....
Nvidia's revenue is made up of.
A, GPU's.
B, Mobile SoC Chips, the CPU is licenced from ARM, the iGPU by Nvidia.
C, some Intellectual Property, such as the PS3 GPU, there may be some other comitial aspects I don't know about.
AMD have had a string of contract wins lately that are beside the Game Console wins, which is great news, AMD is also continuing in its restructuring and the paying down of the remainder of its debts, they say they will be profitable in Q3 this year, this is before the revenue from the xBox One and PS4 kicks in.
Nvidia are profitable and have been for a very long time, they also have a much larger cash stash than AMD.
The only problem Nvidia have (and it is a big one) is that they are almost entirely dependant on GPU sales, and they don't really have enough IP to branch out, they would have to rely on Intel and AMD to licence them the IP they would need to break into growing markets in a way that is significant enough to sustain them as they currently stand.
