With dies this large, how many fully working dies will Intel be able to get from a single wafer? I would bet it wouldn't be that many and even selling them at a couple of grand each would likely make them a loss?
These will be 28 core dies salvaged, they are 700mm^2.
On a 300mm Wafer Intel would get about 50 dies with 95% yields, a 300mm 14nm costs $4.800. Comes to about $95 per die.
Its not so much the cost, AMD's 64 core chips will cost about half that with the IO die, its the amount of wafers used to make those dies, AMD get about 1,200 8 core chiplets out of the same size 7nm wafer, about 150 TR 3990X CPU's, when you have a limited wafer supply, which apparently Intel do, using that many wafers to make your CPU's really hurts your supply. you have to charge a lot of money for the CPU's to make up for lost wafers you could be making many more much smaller mainstream CPU's with.
It makes one wonder if Intel suddenly have a huge supply of them because someone cancelled their massive order of 28 core server chips and need to get rid of them, how could that have possibly happened? who else makes X86 server chips???????
