They are making 78% of margin on those chips - I would think that that leaves a lot of bargaining power to TSMC. They would loose much less than Nvidia.
Nvidia may be working with Samsung, but they don't have any alternative for now.
So my understanding is, that TSMC currently has the monopoly on producing Nvidia chips, and Nvidia obviously has the monopoly on selling those chips.
And somehow, Nvidia is extracting 99% of profits from that situation, while TSMC is getting close to nothing. My understanding of game theory is that it should be way closer to an even split.
Could you elaborate on why the prices are defined by AMD margins ? I'm obviously missing something, but can't see what.
The way that could play out is that Nvidia wouldn't buy directly from them, but somebody else purchases cheaper from TSMC and then Nvidia buys from them.
So TSMC would have to increase prices for everyone, but then for some it would be too expensive and so they would lose those customers.
Nvidia engineers work shoulder to shoulder with TSMC to squeeze everything from the architecture even before the fab is build. TSMC makes custom job for their best customers.
For old established process it's possible to send design and get functioning chips without a huge R&D hassle and loss of performance.
TSMC fab capacity and packaging are the bottlenecks for revenue growth.
