Come on now. Why would they be so desperate to build new fabs all the time, expand their business into the US (see TSMC Arizona expansion), face all the difficulties and spend hundreds of billions of dollars if they were withholding production? Their chips are in almost every device you use in your daily life, and you're likely not even aware of that.
AMD is reliant on TSMC all the same, and the decision to place Radeon in a lower priority was a decision of their own - margins on EPYC and Threadripper products are insane, and Ryzen makes it up to the lower margins in sheer volume. Said margins aren't attainable on their graphics products, even in the workstation segment.
Desperate? meh begrudgingly is more like it
of course I know TSMC makes chips for _everything_
but I remind you that the new fabs
in the states don't exist because TSMC wants them too they exist per us-gubberment mandate and gubberment-monies without either of those mandates.
tsmc would be far less inclined to build these new fabs so I would hardly call them 'desperate' are new fabs good for them in the long run? yep. in the next year or even 3 Nope.
and then there is the problem of who you are going to get to staff and run the US Fabs because there isn't enough labor force in that sector stateside ... yet
and AMD is going to miss the AI-supertrain to money town (again) and remain forever the underdog because the people in the gpu division are clueless
nobody disputes ryzen(anymore) but not relavent to nvidia/partners playing pin the tail on the price-fixing donkey
Intel is comming up fast but there idiotic choice to kill larrabee years ago is biting them hard
Nvidia basicly has a Run of the entire Gpu/AI market completely unchallanged in the DC for AI which is where all the money is going to be.
you put a giant bag-o-dollars in front a company they are going to make a grab at it and they WILL break every rule and step on every toe to get it
which is why a hawk eye needs to be keept on every move and statement they make as well as a eye on anybody else that stands to profit from the situation
cat being away mice gonna play. childern gonna break shit while the parents are out of town
