Xyz ISA = Instruction Set Architecture
In other words, i586-compatible.

Intel engineers have recently been claiming that full speed, then halt,
is the most power efficient approach on "modern processors".

There's a lot it doesn't provide. I'm inclined to think that if 86duino could sell for less than $80, it would be more for your money than a $60 Galileo.
