The Am386DX-40 gets barely warm (as opposed to a 486DLC). AFAIK, it differs from the intel ones by using a static CMOS design.
AMD used an 800 nm process.
Intel started with 1500 nm in 1985, and later moved to 1000 nm.
The 1000 nm should be quite close to 800 nm, especially at the end of its lifetime, when the process was fully matured (the first 486es were also made on 1000 nm, even the DX-50 and DX2-66).
Which is why I think the later 386DX-33 CPUs could probably overclock quite well, and should be able to run at 40 MHz as well.
