Has anyone ever estimated how much it actually costs intel to fabricate these high end xeons? I know larger monolithic chips are harder to make but on a $ per core basis the cost of these is extreme. How do you think the innevitable 64bit ARM-A57 server chips will impact pricing, will intel be forced to lower prices or will you see them push prices even higher to extract more money from customers that cannot feasibly migrate away from X86 or require very high performance per thread?
