I think this year was an important year for AMD in that they launched three major new product lines: Zacate APUs, Llano APUs, and Bulldozer CPUs.
Zacate is a winner. I have built three Atom-based nettops and almost 30 Zacate-based nettops this year. I have not recommended a single Atom-based netbook since Zacate netbooks became available. That said, the netbook craze has really died off with the rise of tablets.
Llano is a winner in the budget and mid-range mobile sectors. There are a lot of very good Llano-based laptops, and I've been recommending a lot of them. At the high-end, you're still better off going Intel/AMD or Intel/Nvidia. Llano on the desktop is a harder sell, but I'm building more Llano desktops than either Intel/dGPU or AMD/dGPU desktops now because most of my customers are into light gaming on 1333x768 displays. I still build more budget AMD or more powerful Intel systems without dGPUs, though.
I still don't think Bulldozer is a total failure because there are niches where I think it outpaces the Intel competition, but in light of many of the good arguments made in my Bulldozer response thread, it's clear to me those niches are not numerous, and Bulldozer is definitely not a success.
What's clear to me at this point is why AMD rushed to get Llano out in numbers and delayed Bulldozer: Llano is a very good product, Bulldozer is a mostly bad product.
I've been watching AMD's stock price like a hawk this year knowing the company's success would hinge on the success of these three product lines. Zacate is very successful, Llano is successful, and Bulldozer is not successful. I have a limited understanding of what drives stock prices, in that I think growth is what makes a company's stock price go up. This is why Intel and Microsoft's stocks have been relatively flat for years - both companies make gobs of money (hence the great dividends), but neither is really growing. AMD has the potential for growth. ...But it's easy to have potential for growth when you have very little market share (see Apple's history over the last decade).
The question now is, how will AMD grow as a company? They clearly can't compete with Intel's massive R & D budget and they can't compete with Intel's far superior process technologies.
What troubles me is that if AMD collapses, dGPUs become monopolized by Nvidia, and CPUs become monopolized by Intel. This is an enthusiast's nightmare, to be totally blunt.
