Man. It's so f**king obvious that nobody can "source" Avalon chips from TSMC that is ridiculous you even asked. Do you have a clue of how a company like TSMC works? They are producing chips for EVERYBODY, including Apple or Nvidia, their security standards are top-notch and applied to every customer by default. Probably they don't even know who "Avalon" is, very likely every customer is just a number for 99.9% of the employees, and there's no friggin' way you contact TSMC and somebody is able to tell you that they are not manufacturing for this or the other customer.

Sorry, I didn't read the other page, I was (and I am) too amazed that you dared to ask such a thing to your "contact", and even more amazed by the fact that you had the guts to post such a ridiculous nonsense in a public forum.

And BTW, you have the proof now that "this person" is at the "an uncle that works at Nintendo" level, because he laughed out loud at your face telling you that somebody told her that TSMC is not producing those chips anymore. Only two options here bro, either she is a clown, or she is clueless, otherwise you just do not say such thing because you would feel ashamed.

AND BTW: next time ask her to "source" you the prototypes for the next iPhone from Foxconn, and when she replies that "somebody told me Foxconn is not manufacturing Apple devices anymore" you tell us, ok?
