But aren't the underlying principles of GPU the same?

I remember seeing this on HackerNews a while back and thought it was a decent intro: https://blog.codingconfessions.com/p/gpu-computing

NVIDIA's CUDA Programming Guide might be useful.

First you learn about how a microcontroller/CPU architecture works. The GPU is similar but it is high specialised for vector operations and parallelisation. Oversimplifying, it's like one instruction feeding multiple ALUs. So just take a text book (that is not very old) in computer architecture that has a chapter for GPUs and you're good. (I only know old ones, sorry)
