Well why can't we find any actual chips matching that specific performance range, when it's already middle of March 2020 (same year PS5 is supposedly launching)?
That's been my biggest skepticism behind some of these newer spec rumors. They all feel almost reactionary, and continuously creeping upward, while varying wildly almost as consistently.
But to give you an example, you can technically reach 11.5TF with a 40CU chip if you have all 40CUs on clocked @2.25GHz. I mean, if Oberon has already been tested at 2GHz what's to say they have not pushed it further than that...
...is how I try relating the testing data with, say, your claim here. Except the problem is there is no clock setting in any of that data actually reflecting 40CUs @ 2.25GHz. So does that leave another yet-undocumented Oberon revision? And if so what's the setup for that revision differing it from the most recently-known one?
Because your word alone isn't going to get me to discard actual data completely. At the very least, it's speculation I can combine with that data and try finding something in the middle. But the middle doesn't necessarily have to be the obvious middle I suppose.
