5-6% is cow dung, AMD's profit margins currently stand at 38%, as public record, Intel are at about 50%
I just had a quick look at what they are on about, they are using the net profit to make their arguments, yes its moronic... net profit is what you arrive at after paying down exist debts, R&D spend and a whole lot more besides.
What matters in their argument, the argument that they are making is that AMD need to put prices up because they are not making any margins on their products, in that what matters is what the difference is in what it costs them to have it at the stores ready for you to buy and what they ultimately get for that product, anything else that they chose to spend money on there after, like R&D spend, voluntary debt reduction, IP purchasing.... is nothing to do with any of that. if it costs me £100 to get my product to where you can buy it for £140 i have a gross margin of 40%, if i spend £30 on R&D i have a net profit of 10%.
look you cannot run a business with 5% margins and survive for long unless you have a lot of savings, because you have no money to future proof yourself with, its why pre Bulldozer years AMD had $3bn petty cash and now have about $500m and a lot of that is recouped post Zen.
Its a complete and utter conflation of the facts, it could be deliberately or total misunderstanding of what they are talking about and frankly with modern tech journalism i don't know which it is, it could equally be one or the other.
