Reference for GTX 970 Internal Architecture Image

I found multiple online posts that show this image of the architecture of GTX 970

The link to the primary post is:

The post does not mention the source of the image though it does say that the image was released by NVIDIA in form of slides. I would like a link to those slides (As I am writing an academic paper that requires me to use that image and I need a reference for this image, preferably a link hosted on NVIDIA’s site to give it authenticity).

Thanks in advance.

That image/those slides were provided only to various news outlets that were reporting an issue with the GTX 970. I don’t think you will find those published by themselves anywhere from a NVIDIA source, and NVIDIA has no plans to make a posting or publish those at this time.
