As far as I can tell, 75% is gross margins, and 75% is fairly standard for gross margins. Net profit margins are only 48%, although that is still rather high. I would expect more around 30%, which it looks like their historical net margin has been, so that's a good point. I think it will be hard for competitors in the near-term, unless AMD has something close to ready to go. My understanding is that it takes about 4 years to design a CPU through to manufacturing; GPUs might be quicker since I think they are simpler. I think the current margins are due to higher prices because of demand vs supply. I guess the question is whether demand decreases, and if so, does it decrease first or does a viable competitor arrive first? And even if a viable competitor arrives, does it affect demand? (AMD CPUs have always been cheaper than Intel's, but until recently it did not affect Intel's margins because Intel always had the better process and therefore the performance edge.)
