The people on the "AMD slash and burn prices" side of the argument really need to get consistent. So Intel can't tolerate losing any of their margin, but they can tolerate going straight to 0%?
You need to be rational and recognize, that if it actually starts to hurt Intel sales, they will respond, and lower prices, and Intel almost certainly has lower production costs, that make it insane for AMD to approach anything near starting a pricing war.
That isn't what is being said at all.
My post simply states that any additional sale for AMD, regardless of their margin on it, is one less sale for Intel, for which they get a 0% margin.
There's no reference as to who it affects most at all, since its pretty obvious that Intel will still be around and kicking for quite some time yet.
But let's humour you anyway.
(figures used only to demonstrate effects, and attempt to represent current market share...by proportion... and margins).
Intel sells say 90m CPUs with $50 profit per CPU, representing a margin of 40% and an ASP of $125.
AMD sells say 10m CPUs with the same margin but an ASP of $100, so make $40 per CPU.
Intel makes $4.5bn versus $400m for AMD.
AMD drops its margin to 33% and sells at an ASP of $90 instead, making $30 per CPU. They do so with a better CPU at each price point, significantly better, and as a result they sell 20m CPUs versus a drop to 80m for Intel.
AMD end up with $600m profit, a 50% increase, and Intel end with $4bn profit, a drop of 11%, or $500m.
By taking a small reduction in their own margins they not only close the gap in market share, but also significant narrow the gap in profitability.
Whilst we can argue that Intel has deeper pockets, so can sustain their position for longer, the reality is that shareholders won't like it. Sure, they can cut prices and margins themselves, but it wouldn't alter the fundamental issue which is that AMD would have the better product at every price point still.
Yes, I appreciate that these numbers are pulled out of thin air, but they do at least highlight why AMD should look to strike hard whilst the iron is hot.
