The 14nm process should bring 35 percent less power consumption and have 20 percent increased performance with a 15 percent smaller die area. It's getting more expensive to build chips on newer and smaller process nodes, and one way to reduce the cost of the chips is to reduce their size, even if that means a lower increase in performance.
What horrible writing. Good grief, how could this pass an editor. It's completely unclear, and borderline misleading.
For the first sentence, compared to what????? To the 28nm most companies are on? Nope. What then? Compared to what the node would be like if it were not a FinFet? Terrible, terrible writing.
It's not more expensive to build chips on newer nodes. It's generally cheaper. Again, learn how to write clearly. It's more expensive for the same die area, but less expensive per transistor. Since a direct shrink dramatically lowers the size, smaller lithographies cost less once it gets past the low yield phase. 20nm is one where this holds less true.
That's probably what you mean, but it's written so poorly, no one can figure that out unless they already know it.
First, 14nm is not a meaningful term, and doesn't reflect the actual lithography. It's just a name the company gives the process. They try name it as if it were the actual lithography like it was years ago, to indicate the size reduction, but it's not an absolute term. Intel's numbers are always fudged, a little, so that, for example, their 22nm was really more like 24nm in terms of shrinkage. But, they can call it what they want. The point is, this isn't necessarily better than the 16nm process. It could be, but each company names it what they want.
Keeping in mind Global Foundries licensed the technology, and is calling it, 16nm, you get a pretty good idea of how there is some room to play with the names.
While it's interesting AMD will be using this, it's also important to not read to much into it. Since their next generation of 'big' processors isn't out until 2016, and then almost certainly on GF (which works fine for Samsung, since they can switch relatively easily between the two since the processes are so similar). Carrizo is on 28nm, so there will not be any large processors made at Samsung in 2015. This leaves the smaller markets. Since we know Puma's successor is going to 20nm, and the R9 390 is also 20nm, it's not clear what they would switch so quickly to Samsung's process in 2015. More likely, they will be using the process, but in 2016. Of course, anything is possible, but there aren't too many scenarios where their bigger product lines would switch so quickly, considering AMD has had to cut R&D, and does not in any way want to be on the cutting edge of working with new manufacturing processes, except in limited ways. Rory Read called it "burning cash". So, I'm skeptical we'll see any volume from AMD in 2015 on this process.
Of course, I could be wrong.
