that is what is happening right now, thats the whole point, Intel has gone low enough and performance of every single Intel CPU (core duo) is higher then AMD for the $. So AMD just did or are they planning on another round a price cuts, thinning margins is not where AMD wants to be at this stage, but they have to do it to keep the marketshare bleeding as low as possible. The company is already cash starved as it is.
There are many factors here not just the one you mentioned.
Just a general overview of how I look at company strength and investment for AMD:
AMD has 5 main areas of diversification in thier structure that bring in money (I know they have other areas just that money wise they are much smaller):
CPU
GPU
Motherboards
Handhelds
notebooks
CPU by far is AMD's bread maker
Handhelds are high profitablity
Motherboards go hand in hand with CPU
GPU are a finishing touch to the whole PC package
Notebooks is a factor of both the GPU, motherboards, and CPU
Handhelds won't be sold, high margins, means always money with no worries.
CPU's and motherboards go hand in hand, if we can sell a CPU, we can give a motherboard at almost no profit not a big deal, this is what Intel has been doing.
GPU definitly not as high margin as CPU's, developement time is very aggressive R&D money is increasing on a per year basis, unlike CPU cycles where it might be 2 years or more in some cases for a totally new architecture.
notebooks, good profitablity, great for selling the complete pakage and keeping margins high.
So now what seems to be the place that could possible be cut, I'm not saying it will be cut, just possibility if AMD stays in the rut they are in right now.
