On: 8OD – Arduino form-factor Intel 8086

I imagine an old CPU like this would draw a lot more power than anything recent, no? Or is it offset by the fact that it runs a lot slower?

It depends. Newer remakes (such as the 80C86) will use less power, but if you use original parts, then they're going to suck power.
