At a size on the order of 1um, it's going to be a long, long while before this becomes a commercially viable competitor to bulk cmos. Doesn't matter much for a CPU if your transistor can switch 1000000X faster if you can only have 1/1000th of them on a die. Your speed would ultimately be limited by the physical wire delays anyways.
Not to mention that it's using "exotic" process steps which means capacity is, at minimum, decades away from being meaningful.
Don't get me wrong, the research is cool, but it's not going to make "computers a million times faster".
- georgia_peach 4y agoWhat if it ends up in a USB scenario--fewer wires, but running at a higher speed? 4-8x smaller word size to get +10e6 sounds like a good trade. Just think, Z80s & 6502s coming back into fashion. This time, turbo-charged! Chuck Moore was kind of on that beat already with his GreenArrays chips. It will definitely be a while, but maybe not such a long one.

- Thiez 4y agoKey sizes are generally chosen so that brute force is infeasable even with enormous speed advancements. You cannot increment a counter to 2^256. There isn't enough energy in our solar system. So you cannot brute force 256 bit symmetric key encryption using traditional computers. Not at any speed.
