It's easy to understand kid.
AMD is not paid per-unit sold. Rather AMD licenses their technology for a flat fee.
It's peanuts kid.
You might be thinking of ARM?
AMD hasn't made a killing (certainly not like Nvidia do) and yeah margins are pretty thin in semi-custom. However that division (Enterprise, Embedded and Semi) pulled in $2
.35 billion in net revenue in 2018, and unless things have changed, the
majority of that is from consoles (they don't give a detailed breakdown). The more important figure is $163 million in operating income for that division. Thin, but at this scale it makes a difference and I'd very much prefer $163million to $0 or worse.
$2
.276 billion and $132million in 2017, $2
.305 billion and $283 million in 2016.
Capacity at that node isn't much of an issue AFAIK thanks to GloFlo so the same opportunity cost is lessened compared to Nvidia.
I maintain that this probably kept AMD breathing over the years (or at least gave them breathing room) until they could get away from the Bulldozer line.
