You will never see the detailed numbers that you want, BUTFirst point: I would really like to see NVidia's labor/material/fab cost list, with the R&D investment factored in. Everyone complaining here seems to have access to it but I can't seem find it anywhere.
Gross margin = 65% that's the money left over when subtracting the direct cost of production
Operating expenses = $1,960 = ~27% that's the money they spend on paying salaries doing advertising r&d and all the other ongoing costs.
Net income = 2,464 = ~35% that's the money they "put aside" and their "wiggle room" to make products cheaper if they wanted to.
But of course they also need a good net income to keep being a healthy company.
