What are you talking about?The jump from micro-arch to ISA in a comment to a post literally citing AMD rep clarifying that those are 2 different things is mind boggling.
GCN is architecture, ISA. Microarchitecture is its implementation.
Well, you can call PTX an ISA if you want. Nvidia halfway does. It is worth noting though that PTX is a virtual machine with a defined ISA (read: software). How this is mapped into actual GPU hardware is not well known (and Nvidia does not say). There is enough evidence to say the ISA underneath PTX is different between GPU generations. Nvidia drivers contain a compiler that compiles PTX code into binary code.
