> AMD 2019 Profit (as earnings per share): $0.30 [1] NVIDIA 2019 Profit (as earnings per share): $6.63 [2]
> 4.52%, rounds to 5%, as I said.
You're misunderstanding how to properly compare profitability between two companies.
If Company A has 1 billion shares outstanding and earns $0.10 per share, that's $100m in profit.
If Company B has 10 billion shares outstanding and earns $0.05 per share, that's $500m in profit.
Company A is not 100% larger on profit just because they earned more per share. It depends on how many shares you have outstanding, which is what you failed to account for.
AMD's profit was not close to 5% of Nvidia's in 2019. That is what you directly claimed (as you're saying you went by the last full fiscal year).
AMD had $341m in net income in their last full fiscal year. Nvidia had $2.8 billion in net income for their last full fiscal year. That's 12%, not 5%. And AMD's operating income was 22% of Nvidia for the last fiscal year.
The trailing four quarters and operating income, is the superior way to judge the present condition of the two companies, rather than using the prior fiscal year. Especially given the rapid ongoing improvement in AMD's business. Regardless, even going by the last full fiscal year, your 5% figure is still wrong by a large amount.
Operating income is a key measure of profitability and it's a far better manner of gauging business profitability than net income at this point. That's because the modern net income numbers are partially useless as they will include such things as asset gains/losses during the quarter. If you want to read up more on it, Warren Buffett has pointed out the absurdity of this approach on numerous occasions (if Berkshire's portfolio goes up a lot, they have to report that as net income, even though it wasn't a real profit generation event).
I didn't say anything refuting your revenue figures, because I wasn't refuting them. I'm not sure why you mention that.
