Hardware-related topics for game development

So, I have a potentially difficult question and I think that r/gamedev is my best hope of finding an answer.

The question is, "If I wanted to understand, to some degree, all technical conversations that could realistically take place inside between developers in a company that designs gaming consoles, what topics would I need to have a functional understanding of?"

I know it sounds extremely weird, so let me explain why I'm interested in this. I'm a translator/interpreter who often works with game developers. There's a company I'm interested in working for, but the job listing, roughly translated, states that I would need to, "understand technical topics, both software and hardware-related, used in game development." I have a CS background and my job forces me to keep myself up to date, so the software part is not an issue. Thankfully, I just need to be able to read libraries and understand APIs instead of, you know, using them.

The problem is that in all those years in university, we barely ever touched hardware. We studied some very basic CPU architecture in order to learn Assembly and I think I heard the word "GPU" once when we were writing shaders, but that's about it. I don't even know the scope of what I don't know. So, is there anyone who has any clue about what kind of discussion may hypothetically go on between developers when building a console? Should I study chips? Buses? Integrated circuits? Lasers?
