Intel performs equally well under open source OS.
Intel does not always have the best uarch, period. that has gone back and forth based on workloads for years, and YES INTEL CHEATS WITH ITS COMPILER and many software librarys have been built with the Intel code compiler, thus further pollouting the software ecosystem, AMD has a fortran software stack that sucks, becuase they used the intel compiler and it borked the performance of their fortran implementation.

I know margins on silicon itself are pretty decent but with no way of knowing how much it cost to develop PD it's all just speculation. I just can't imagine Plan A was selling the flagship model for 200 dollars when a decade ago they had chips that cost over 1000 dollars like Intel.
AMD makes a profit, but not every profit is large enough for the B.O.D. short sighted thinking in this economy.

(Fun business fact: If you own a business that is facing financial burden, you NEVER EVER EVER EVER take money out of R&D. If you are rich, pay money out of your pocket to avoid the failure of the company. Why do something so crazy? Well if you take money out of R&D and you are trying to sell stuff that comes FROM R&D, then your secret projects will fail and you will be forced to sell crap. This will further cripple your business, and lead to your demise. )
As soon as they touched that money, it was the end of AMD. So really the performance issues with AMD stem from morons who have no clue on how to run a tech company rather than any software based issues.
Phenom got trampled by much the intel optimized software at that time, they had also invested into optimizing for older code paths, that was then, this is now. AMD is designing a chip for 2015 by the looks of things, not 2011.
Becuase the instruction dispatch in most FOSS software does not look for genuine intel, it checks cpuid for flags.

actually, BD's sse/sse2 etc performance is pretty good as well and its integer performance isn't horricifcally bad either.
