I mean can you find the bit adder figures for, say, TSMC N7 or N5? I poked around google scholar and wikipedia for a few minutes before giving up and hoping that someone up with the times would know exactly where to look.
- mlyle 6y agoNo. Those are subject to NDA, but are broadly similar in fmax and prop time under reasonable voltages. I think it's exciting here that they're dicking around with new technologies in their infancy, and in a few coarse design changes of cells went from 60% of CMOS leading edge to about the same numbers. Of course, total system power, etc, is atrocious, considering that this is cryogenic, etc. You need a lot of logic before this could come ahead in efficiency.
- jjoonathan 6y ago> No. Those are subject to NDA Yeah, that's what I thought and why I settled for a less accurate comparison. > I think it's exciting I think it's exciting, too. The extent of my claims is "no, this does not mean 100GHz LN2 CPUs in a few years." I did not intend these remarks to be meaningful to chip designers, only to CPU consumers who see "GHz" and think "CPU clock speeds." The leverage of having a slightly better fundamental device is extraordinary. We should spare no expense looking for them and leave no stone unturned.
