512-bit? Sweet jebus........... Though I have to say, I'm not surprised and it would explain a lot about the new consoles (especially the PS4's absurd memory throughput) and if they have been working with MC and Sony, then they will have learnt a lot on how to customise their gear - one being that they would need gpu's to be able to access the vast system memory rather than having it's own independent memory.

If you take into account all the process node shrinks and how prone to error the silicon is when attempting photolithography I'd be willing to bet the fastest GPU achieveable isn't going to be more powerful than the PS4 by a factor of 8.
Edit: To reach the smallest process nod your going to have to wait 10 years.

Do not underestimate the capabilities of AMD and Nvidia to release increasingly bigger cards in order to keep fooling clueless enthusiasts they are seeing real, Moore law-like progress as far as shrinking and efficiency goes. I mean, remember that once upon a time this is what we called high-end... nowadays it wouldn't pass as the integrated video card of a low end laptop:

Do note that the smaller the process node the more likely the bigger dies are prone to error's. So I wish the manufacture's good luck for being able to get any decent yield beyond a 370mm^2 at a process node of 5nm.
Edit: BTW the TITAN has some disabled units due to how prone that thing is to error's.

They are good upto 2026 iirc, as in they know the techniques to mass produce the dies at an affordable price, however beyond that, they are stuffed - everyone at Silicon Valley has come to that agreement. The good news is that they had a breakthrough with graphene and there is enough money to go into that. However, when graphene dies come in, Moores law will go tohell as graphene can clock well over 400GHz, and that is not also taking into account that less logic gates are used to perform logic functions (due to the gates being hybrid gates).

Moore's law has to do with the doubling of transistors so how does frequency mean the doubling of transistors ?
But how are they going to cool off that type of heat ? (The forumula for cpu power is (C)(V^2)(F))
Can you explain to me what a hybid logic gate is. (I know what a logic gate is but how can a gate possess more than 2 logic types or do you mean you can create a bybrid logic gate that is not an AND, NOR, OR, XOR, NAND, or NOT gate.)
Edit: I forgot XNOR.

Yes, that is right, but when the trans double, normally the proc power doubles at the same time. Graphene would demolish this as you could have a chip with less transistors still utterly outstrip a current proc. making Moores Law useless.
Graphene requires far less power and is highly resistant to heat, also you don't need mass power to clock at that speed as you are not looking at fermi levels to overcome (uses "negative resistance").
Basically using this negative resiatance, they made something that works essentially the same as a XOR gate, but takes up far less room than a current XOR and they only needed 3 of these negative resistance transistors to make one.

Essentially, we are all going to have to go back to uni to relearn fundemental circuit or proc design when these bad boys come out.
