AFAIK rather than being 3d as in what people always talked about for 3d, IE stacking transistors on transistors for huge transistor density. This is merely(though not bad at all) a transistor on its side, which due to the space saving allows more gates to be used rather than more transistors.
Its pretty good but 50% power saving dropping from 32nm to 22nm is, well, expected, though its getting harder to get the same power savings you'd get from say 130nm to 90nm.
Real 3d(stacking, silly transistor density increase) is still to come, if its possible.
There's pretty much a new fancy name for whatever new method they bring in every gen.
They also like to demonstrate cutting edge
CPUs by serving up webpages, playing Hi-Def video, and by describing the
graphics and physics of a game, seriously that man must have presented the most pointless video ever
Its the way CPU marketing is going, 99% of buyers don't care how fast it folds, or encodes, or pretty much anything apart from game, bring up web pages and accelerate high def content. Its what 99% of Dell/HP/Acer/Asus/Apple buyers actually do with their computers.
Thats why AMD doesn't have to compete on the CPU(they still will) to "win", because in the same things that Intel themselves are talking about their CPU's for, the GPU is massively involved, and a AMD cpu + gpu will beat anything Intel's got in most of these area's. AMD are doing great, no matter the process as frankly the game is moving from CPU performance to overall performance in what 99% of people do day in day out.
Intel just have a pretty easy time of it, because of the process lead they can just pump out smaller chips that CPU wise beat AMD easily and for years have been able to charge more. IE they just make huge margins compared to AMD, thats the biggest advantage on processes, not flat out performance but being a process ahead of everyone else means you can make similar things to everyone else, at half the size, higher yields and way higher profits.
If Intel/AMD market share stabilised at 50% each, Intel would probably still make 4-5 times the profit AMD could.
