I don't think it is a GPU, rather it is probably very similar to a DSP/Neural Network chip. Lots of matrix multiplication capabilities and streaming data.

(Of which https://en.wikipedia.org/wiki/Image_processor are a subset of, which someone else in this forum mentions.)

DSPs are similar to GPUs in many respects but they are also similar to CPUs in many respects, but it doesn't make them the same.
