Question Regarding Reference vs Non-reference Cards

[snake731]

I'm still relatively new to all this but I'm kinda confused when it comes to reference vs non reference graphics cards... the main differences between reference and non reference cards are usually pcb layout, vram, coolers, and clock speeds right? So then couldn't you just buy the reference card, if the cooler is pretty good, and then overclock it to (or past) the non-reference's speeds? I don't really understand why non-reference cards with the same vram as the reference cards are so much more expensive. Or do they adjust power or something to hit a clock speed that you normally wouldn't be able to with the reference card?

It is easier to overclock safely on non reference because their coolers are much better (not counting waterblocks) . Also there are other features that make them great.

Reference is AMD'd stock spec that they give to manufacturers,they then take this and beef up the VRM or change the layout to improve cooling or whatever to their design goal.

 

The actual die doesnt change,the performance is still a lottery unless there is binning being done,the performance enhancements come from the design changes,ie more power phases,better chokes and mosfets or,an improved cooler design.
