They can, as calculated by switching delays of simple circuits like inverters and NANDs (so simpler than a FO4). Actually it's probably more like 200 than 300,

They can, as calculated by switching delays of simple circuits like inverters and NANDs (so simpler than a FO4). Actually it's probably more like 200 than 300, I haven't seen 3nm models but transistors are still getting faster.
