Comment on Cloning a 6502 Apple-1 in just 930 logic gatesComments−oneplane6yI wonder how big the difference is between current logic gate performance vs. what we have available when the 6502 was 'new'.−tyingq6yNot a lot really, as far as the 74xx series goes. 10ns gate delay for the original 74xx TTL chips, vs 6ns gate delay for the current CMOS 74HCxx chips. The reduced power consumption is a bigger benefit.−oneplane6yIs that due to both the chemical gate setup as well as node size?

I wonder how big the difference is between current logic gate performance vs. what we have available when the 6502 was 'new'.
Not a lot really, as far as the 74xx series goes. 10ns gate delay for the original 74xx TTL chips, vs 6ns gate delay for the current CMOS 74HCxx chips. The reduced power consumption is a bigger benefit.
Is that due to both the chemical gate setup as well as node size?
