Additionally, Intel's crown jewel and historically a critical enabler of its competitive advantages over the competition -- its Technology and Manufacturing Group (TMG) -- has also struggled to execute for years now; critical manufacturing technologies that are used to build virtually all its processor products almost always see delays now (impacting competitiveness/product schedules), and even when they are finally forced to see the light of day, there seem to be extended yield challenges -- negatively impacting the company's profitability and/or its ability to apply its newest technologies to key product segments.
Intel has some serious issues that it needs to work out in its core businesses -- namely, it has to improve its product execution in PC and data center processors and platforms while at the same time substantially improving its execution in chip manufacturing technology.
