In CMOS the killer is that they consume power when switching (power ends up being a square of switching frequency). So if you switched. 10x, you'd have to somehow dissipate 100x the power.
Your core might be small, but the industrial-sized refrigerator needed to cool it suddenly isn't.
- baybal2 8y agoI thought recently, given how bad leakage gets at <10nm, why not to go back to RCL or TTL logic? A similar line of thinking lead to source-coupled logic being resurrected for use in high speed PHYs https://en.wikipedia.org/wiki/Current-mode_logic https://en.wikipedia.org/wiki/Current-mode_logic
- neltnerb 8y agoMy question had the assumption of something akin to vacuum transistors that allow high frequencies without the heat generation, but yes, I agree that the current technology won't scale by 10x without a generational shift in underlying approach away from MOSFETs.
