I don't think that understanding how pcbs are made, the architecture of cpus, gpus, ram modules, etc and all of that in order to have a working understanding. If you just want to know what each component does and how they affect performance and all that, there isn't a point in knowing all of these detailed things. If you just want to know it for the sake of knowing it, that is fine, but you are out of the league of the understanding of most people on this website. Most people on tech forums just want to have a working understanding. Understanding the underlying hardware and a deep understanding of how things work would take a lot of time and wouldn't help with making a good computer.
Most people are, but wanting to have a very good understanding and knowledge about this stuff is completely understandable. But most people wouldn't even know where to look for that sort of stuff. That is why I am trying to clarify with OP.
(A good in-depth breakdown of the cataclysmic shift in GPU architecture brought on by parallel shader modules. I suggest reading up on the Fermi Architecture, TeraScale 2, Kepler, and GCN as well to get an exceptionally broad understanding of how GPUs have evolved in the last decade.)
Ahh, should have mentioned this was purely for interest's sake and furthering my own knowledge as opposed to learning how to build a computer. I'm a Compsci/Infosys student but i'm super curious as to the electrical engineering side of things as well.
I've also been listening to a lot of the guys over at PC per and some of the things that Wendell talks about still confuses me, so i'm really just trying to extend my technical knowledge.
