The design is done once and gets spread over the millions of units that they are selling.
the software is a running cost that should be spread over tens of millions sales.
They are doing at least 10x
You don't just push a few buttons and have everything work. Even if the core architecture is the same, design, testing, and validation need to happen on every single part. It takes time and money.
If you want to say that Nvidia's stock is incredibly overvalued with a market cap of ~$3.39 trillion, yes, I'd say that's 10X to 30X too high. LOL. But the earnings reports are pretty straightforward.
That shows $35 billion in gross revenue, $20 billion in net revenue (give or take depending on GAAP/non-GAAP). So in effect, Nvidia spent $15 billion and earned $35 billion. Compared to last year, it spent $8 billion and earned $18 billion. So it nearly doubled expenses and income in the past year.
Either way? It's more than 2X and less than 3X overall margins. And yes, that includes bonuses and a bunch of other stuff, and you can argue maybe the "real" numbers should show a margin of maybe up to 4X. But 10X? Not a chance. 10X would be if Nvidia spent $3.5 billion to make $35 billion, which it absolutely could not do right now. Just the data centers and main HQ building are going to have costs in the billions I suspect.
