Reply to comment by Yeetus_McSendit in Samsung develops industry’s first 12nm-Class DDR5 DRAM by thebelsnickle1991

Well transistors vs capacitors.

But if you really want your mind blown, the "5 nm process" isn't actually transistors that are 5nm in length. These numbers are more marketing terms and names of distinct generations more than actual physical dimensions.

In fact, the 5nm generation of CPUs actually are closer to transistors that are 35-40 nm in length.

The physical dimensions and the names haven't really been aligned in nearly three decades.

Drives me nuts. So misleading.

is 5 nm the resolution of the process? So the transistors aren't 5 nm, but creating a usable semiconductor structure requires precision on the order of 5 nm

“5nm” is not related in any way to feature size or precision. It’s just a marketing name for the manufacturing process that followed “7nm”.
