correct me if I'm wrong, but literally the first 3nm computing devices to land in consumer's greedy paws. 12-atom wide transistors. what a SLAP IN THE FACE
WHERE ARE MY 11-ATOM TRANSISTORS?? HOW CAN YOU SLAP?!!
3nm does not refer to the size. It refers to performance
3nm refers to the smallest possible feature size - the transistor would be bigger than this.
It can correlate with performance, but it is not performance.
there is no 3nm feature on a 3nm transistor, that's wrong too
https://en.wikipedia.org/wiki/3_nm_process the gate pitch is 48nm, metal pitch is 24nm
lol what
3nm is the name for node that is better than 5nm which is better than 7nm, which is better than 10nm, etc. and you can only compare it to the previous node by the same manufacturer
they literally just multiply by 0.7 and round down, so after 3nm it's 2nm, after 2nm it's 14A - no matter what the physical size is
it's the name for size of the planar transistor pitch that would be required to match it, NOT the actual size of ANYTHING in the transistor and hasn't been since finfet transistors were introduced
