HPU of HoloLens

Hi,
I want to know if the HPU is similar with a GPU?
What's the maximal GPU memory size to load an image/volume?

Thanks.

    2048x2048 should be the max. I thought HPU was inaccessible and provided data to the apu/cpu of the spatial data to process for rendering.

    so you mean HoloLens has GPU, HPU and CPU? For GPU memory, what's the maximal size?

    Thanks a lot.
