This is painfully hardware illiterate.
First off, the actual person doing this from the article in the Tiawanese Economic Forums was a financial analyst, speculating, when put on the spot based on trying to recall information they saw online (which would be the lapsu$ ransom attack info, which they butchered) as stated in the actual article this information comes from.
Second off, the cortex a78ae is a specialized safety processor that runs all of its calculations twice to double check them. It can not be used for a video game system. Because duh.
We know what the cpu is thanks to Nvidia employees making commits to the initialization calls in a public Linux archive they thought no one paid attention to.
I would state it again, but I'm done providing information to useless media outlets who will just butcher it and somehow turn it into misinformation.
