How fast would those old 16-bit chips go if they were made with modernproduction?

The old original 8086 & 8088 topped out at 10Mhz (originally produced at
4.77Mhz). The 80186 & 80188 were the embedded versions of the 808x, but
otherwise pretty close to identical. Well, it looks like the question
has been answered: between 55 & 66Mhz.

EEProductCenter.com :: Intel-compatible processors upgraded to operate
up to 66 MHz
"The IA186EB and IA188EB are form, fit, and function compatible with the
original Intel 80C186EB, 80C188EB, 80L186EB, and 80L188EB 16-bit
high-integration embedded processors. Additionally, they have been
upgraded to operate at 5.0V or 3.3V. The Innovasic version operates up
to 66 MHz at 5.0V and up to 55 MHz at 3.3V."

I'd be curious to know any further information on the technology used,
since they don't really mention much in the article. Our 4Mb generation
was 5.0/3.3, and our 16Mb generation started that way, but once we went
SDRAM, 5.0 was a thing of the past. Our current technologies have I/Os
that can live in a 3.3 world, but it's quite painful to deal with such
high voltages. What a laugh! I remember the rough days of getting down
to 5.0-only, and the circuit challenges of getting decent performance
with such low voltages.
