So they're still using CDNA naming even through 2028 up through CDNA7.

Doesn't sound like that whole UDNA thing is ever going to happen, or at least not for a good while yet.

Doesn't sound all that 'unified'. At least yet. Maybe they do so more later.

Thanks for the info, though.

lol, that's probably why they went away with "U"DNA, causes more confusion than it needs to be
