Oh, they vary all right. But Intel innovations tend to get picked up by
AMD sooner or later . So a program compiled for a particular Intel
architecture should eventually work on later AMD chips.
Your "AMD" could still, for example, refer to a K6. That's a
*completely* different chip (than an Athlon), based on a design from a
completely different company (NexGen) .
K6s aren't i686 compatible. I believe that Athlons are. So does the
Linux kernel configuration system.

Were those Athlons or K6s?
Interesting diversion, anyway...
 With x86-64, the process is going the other way, as well.
 AMD bought NexGen when the K5 was late and underpowered, to get
access to what became the K6.
