Not necessarily, there are other kinds of accelerator designs like dataflow architectures or systolic arrays.

Sure looks like it.

But they are ignoring the basic lesson of "new" CPU designs from Transputer to i432 to Itanium to Transmeta.

A new CPU design is easy, it is the compiler to use it that is the hard hard part.

Looked at another way, CUDA is a huge reason NVidia is so big right now. Their GPUs are broadly similar to AMD. Their software libraries are better.

But good luck to them, perhaps they have some great new idea. We need one.

Yep, and they're probably simulating/emulating their CPU design on GPUs already.
