Way back when, most of a GPU was for graphics. Google decided to design a completely new chip, which focused on the operations for neural networks (mainly vectorized matmul). This is the TPU.

It's not a GPU, as there is no graphics hardware there anymore. Just memory and very efficient cores, capable of doing massively parallel matmuls on the memory. The instruction set is tiny, basically only capable of doing transformer operations fast.

Today, I'm not sure how much graphics an A100 GPU still can do. But I guess the answer is "too much"?

Less and less with each generation. The A100 has 160 ROPS, a 5090 has 176, the H100 and GB100 have just 24.
