Listen, as this thread's number one proponent of "it could still be 8 nm because all we have is guesswork," let me say two things.
First of all, the node doesn't matter; the performance matters. Just recently we got reports of the performance basically being within or even exceeding expectations. So who cares about what node is making that happen?
Second of all, kopite may be the one reliable Nvidia leaker, but he has a less than stellar record of accuracy with T239 information. After originally introducing the model number and saying Nintendo would use it, he got all of the following wrong: codename (Drake, not Dane), core count (1536, not 1024), and architecture (it's Ampere, but he claimed it and Orin were based on Ada, called it "AD10F," made confusing statements about T234 or T239 mixing in "one GPC of Ada" which doesn't even make sense as a concept). SEC8N was also part of those claims, so I wouldn't put money on that part either.
I think this WUST thing is a tired shtick. And I wasn't even part of that thread, and have made the majority of this thread's "don't raise expectations without factual information" posts.
