No matter how awesome AMD GPUs are, until they have a truly awesome CPU and at least for several generations in a row, their shares will continue to take a dump.
Their GPU division is a minor part of the business and thus, the stock price. Its made to look worse since they lump R&D costs of APU into the GPU division, but count APU income as CPU. Lopsided as heck.
NV is destroying, utterly destroying, AMD in the mobile GPU area and its a disgrace that AMD, which had earlier 28nm release of a very efficient 78xx architecture cannot get equivalent or more design wins than NV. Every ultrabook that has discrete gpu has NV. Lost opportunity. For every other notebook with AMD, there seems to be 10+ which has NV gpus. It makes diddly squat if NV loses on discrete PC when it gains massively in the mobile space, its a major loss for AMD, period.
Worse than this is vs Intel. Why is it Llano isn't in an ultrabook design but an Intel with terrible HD3000/4000 graphics is ubiquitous? There's no excuse for the failure of execution from AMD's CPU division on this one.
Seriously, i would pay good money to have Trinity in a sleek ultrabook form.
