AMD's siamesed cores module architecture has been used for its CPUs since Bulldozer was released over two years ago in October 2011 to disappointing reviews. It's lead to AMD humiliatingly losing the performance war* against Intel with this design, so I've been wondering why they persist in using it to this day? They've tweaked it a bit here and there, but since it's been over two years now, surely they could design a better architecture instead and take a leaf out of Intel's book to make performance competitive again while being careful not to step on their patents? For all the usual and obvious reasons, I'd much rather see a strong AMD competing head to head with Intel every generation, rather than this performance monopoly that Intel enjoys. EDIT: To clarify, what I meant was that AMD lost the performance war when Intel released Conroe way back in 2006, but remained reasonably competitive, with aspirations of matching Intel's performance someday. However, the Bulldozer release cemented just how hopelessly far behind AMD were, completely humiliating them, with the gap only growing wider as time moves on.
