So nanometers don’t matter anymore? I remember that the part of the selling point of the Radeon VII was that it was the (afaik) the first 7nm GPU. I am aware that CPUs and GPUs are fundamentally different, but I feel like it would be strange for nanometers to matter for GPUs, but not CPUs.
You say it right there...."selling point".
The only reason they bother to tell us the nm number, is to show it is different than the previous thing.
They could just as easily state. 1.8 billion transistors" (the last one only had 1.3B)
But 'billion' is too large a concept to wrap your head around. So "10", then 7, then 4 it is.
Like the new iPhone ads. "with Titanium". WTF does that mean...'with'?
Is the shell made from titanium? Does it use titanium batteries?
Be mysterious....make the consumer think it is something special
The nm race is sort of like the megapixel race in cameras.
At the consumer level, once we went past 5MP or so....more is irrelevant.
I have a pic from an ancient Olympus C-3000. 3 megapixel.
I can count the hairs on the dragonfly's butt, just like I can with my 14mp Fuji.
