There does come a point where if you're in the follow up article discussing what's new in 2 new variants of the 8th generation of a niche product for that vendor it stops being reasonable from them explaining what everything means each time and starts being reasonable to either click the links to the earlier introduction or search around for it to get a proper understanding as if you didn't know "TPU" was "Tensor Processing Unit" then there is a lot more you want to know before reading this article.

To be fair, does it matter? It seems pretty clear what they are to be used for. Does Nvidia define what CUDA is anymore? It doesn't really matter what the actual acronym is.

Maybe they assumed you would just Google it ;)
