what is the difference between an adobe pdf and a photoshop pdf??
That's like asking "what is the difference between an orange and fruit".

A Ps PDF is a PDF. The PDF format allows a wide variety of options. One of which is for some programs to embed ancillary data, that is extra data not needed to simply view the PDF in a viewer such as Acrobat Reader. In a Ps PDF, the whole PDF file is embedded into the PDF complete with layers, guides, ... . This allows Ps to reopen the PDF and use the PSD data recreating all of the layers, guides, etc that were in the original file. Illustrator can create a similar type of PDF that embeds its Ai data allowing a reopened PDF to retain the structure it had originally in Ai.
