Having spent a few years inside of Intel, it's a company paralyzed by meetings and meetings about meetings. People seem to be afraid to make any decisions so they have meetings to talk about the decisions that need to be made and then schedule more meetings to follow up. Working there felt like swimming in molasses. People who come into the company with any experience realize that it's a mess, try to change things in their area, meet resistance and after a while just give up and leave. That's probably why they mostly hire NCGs at this point.
On another point. I'm not sure how much this is true, but I've read that most of AMD's chips are made from the same basic building blocks, and their different CPUs are mostly just a matter of how many these blocks are stitched together along with whatever tuning/other hardware. Such a design is probably very scalable, which simplifies manufacturing and reduces costs. Whereas I heard intel chips have more separate customizations requiring more separate tooling for each of their chipsets, which complicates manufacturing...
Intel is a very odd company, and for all that there are truly brilliant people there, it feels increadingly like IBM of 2003.
