"SIMT" is not an architecture, it's just a programming model that ultimately boils down to wide SIMD instructions with conditional execution. Add that to a barrel processor that can hide memory latency across a sizeable amount of hardware threads, and you've got the basics of a GPU "core".

SIMT is a programming model, you are right.

But in the literature the term "SIMT architecture" is used to describe architectures optimized for the SIMT programming model.

Just search for "SIMT architecture" in google scholar or any other search engine dedicated to academic research, you will see that it's indeed a term used for this kind of architecture.
